Authors: Gaël Pétremand, Jaroslav Bosák

Abstract: Records of Choerades mouchai Hradský, 1985, are reported from Switzerland. These are the first records of the species published since its description and extend its known range to include the Alps. Previously, it was known only from parts of the Carpathian Mountain chain in Slovakia and Romania. A redescription of the male is provided, accompanied by photographs of diagnostic features, including the terminalia, and images of the entire insect. A table listing morphological differences between the males of Ch. mouchai, Ch. femorata and Ch. marginata is presented. The Choerades fauna of Switzerland is discussed, as is the information available about the ecology of Ch. mouchai.

A new osmiine bee with a spectacular geographic disjunction: Hoplitis (Hoplitis) onosmaevae sp. nov. (Hymenoptera, Anthophila, Megachilidae) https://alpineentomology.pensoft.net/article/118039/ Alpine Entomology 8: 65-79

DOI: 10.3897/alpento.8.118039

Authors: Matthieu Aubert, Andreas Müller, Christophe Praz

Abstract: A new osmiine bee species, Hoplitis (Hoplitis) onosmaevae sp. nov. (Megachilidae), is described. So far, this species is exclusively known from the Mercantour National Park in the southwestern French Alps and from mountainous ranges in Turkey and northern Iraq, two areas separated by at least 2000 km. Phylogenetic analyses based on mitochondrial and nuclear genes revealed that H. onosmaevae is closely related to H. adunca (Panzer, 1798), H. benoisti (Alfken, 1935) and H. manicata (Morice, 1901). Hoplitis onosmaevae is presumably narrowly oligolectic and harvests pollen only on flowers of Onosma L. (Boraginaceae). It has a particularly long proboscis, which is probably an adaptation to collect nectar from the long-tubed flowers of this plant genus. The females collect pollen by buzzing the Onosma flowers, a rare behavior in megachilid bees. The species nests in insect burrows in dead wood, similar to H. adunca and H. manicata but unlike other closely related representatives of the subgenus Hoplitis, suggesting a single origin of nesting in dead wood and hollow stems in this lineage. In France, H. onosmaevae inhabits alpine steppe-like habitats close to forests and appears to be extremely local, since only two populations are currently known. The conservation status of this extremely rare bee species in Europe is discussed.

Liste commentée des Cerophytidae, Elateridae, Eucnemidae et Throscidae du bassin genevois (Coleoptera) https://alpineentomology.pensoft.net/article/116799/ Alpine Entomology 8: 51-64

DOI: 10.3897/alpento.8.116799

Authors: Mickaël Blanc, Stève Breitenmoser, Céline Rochet

Abstract: Une liste des Cerophytidae, Elateridae, Eucnemidae et Throscidae du bassin genevois est présentée avec quelques commentaires et annotations. Le présent travail est basé sur des prospections de terrain ciblées, sur une analyse critique de la littérature et des recherches dans les collections muséales et privées. Une espèce de Cerophytidae, 102 espèces d’Elateridae, 14 espèces d’Eucnemidae et 9 espèces de Throscidae sont recensées dans le bassin genevois. 13 espèces insuffisamment documentées (Elateridae) sont à considérer comme douteuses et sont donc répertoriées séparément. Enfin, 9 espèces (8 Elateridae et 1 Throscidae) potentiellement présentes dans le bassin genevois mais pour l’heure non recensées, sont également mentionnées et discutées. Les résultats montrent que du point de vue patrimonial, 44 espèces saproxyliques sont de grande valeur, car rares et/ou exigeantes envers leur habitat.

Distribution of the invasive ambrosia beetle Anisandrus maiche (Coleoptera, Scolytinae) in Switzerland and first record in Europe of its ambrosia fungus Ambrosiella cleistominuta https://alpineentomology.pensoft.net/article/117537/ Alpine Entomology 8: 35-49

DOI: 10.3897/alpento.8.117537

Authors: José P. Ribeiro-Correia, Simone Prospero, Ludwig Beenken, Peter H. W. Biedermann, Simon Blaser, Manuela Branco, Yannick Chittaro, David Frey, Doris Hölling, Sezer Olivia Kaya, Miloš Knížek, Jana Mittelstrass, Beat Ruffner, Andreas Sanchez, Eckehard G. Brockerhoff

Abstract: Ambrosia beetles are highly successful as invaders because they are often transported internationally with wood packaging and other wood products and because their inbreeding mating systems facilitates establishment of invading populations. In 2022, two independent insect surveys in canton Ticino (southern Switzerland) revealed the widespread occurrence of the invasive ambrosia beetle Anisandrus maiche (Kurentzov, 1941) from southern to central-upper Ticino. This species is native to east Asia and has previously been found as a non-native invasive species in the United States, Canada, western Russia, Ukraine and, in 2021, in northern Italy. Here, we present the results of several trapping studies using different trap types (bottle traps, funnel traps and Polytrap intercept traps) and attractants and a map of the distribution of the species. In total, 715 specimens of A. maiche, all female, were trapped, and the identity of selected individuals was confirmed by morphological and molecular identification based on three mitochondrial and nuclear markers (COI, 28S and CAD). Trap samples from early April to early September 2022 in intervals of two to four weeks showed that flights of A. maiche occurred mainly from June to mid-August. Isolation of fungal associates of A. maiche from beetles trapped alive revealed the presence of four fungal species, including the ambrosia fungus Ambrosiella cleistominuta, the known mutualist of A. maiche. The identity of A. cleistominuta was confirmed by comparing DNA sequences of its nuclear, internal transcribed spacer (ITS) gene with reference sequences in NCBI and BOLDSYSTEMS. This represents the first record of A. cleistominuta in Europe. Of the other fungal associates isolated from A. maiche in Ticino, Fusarium lateritium is of note as there is a possibility that A. maiche could act as a vector of this plant pathogen. We highlight several research needs that should be addressed to gain insight into the potential impact of these non-native species and to overcome problems with heteroplasmy in COI sequences in studies of invasion and population genetics of ambrosia beetles.

First detection of ‘Candidatus Phytoplasma ulmi’ in Switzerland and in Orientus ishidae Matsumura, 1902 https://alpineentomology.pensoft.net/article/115588/ Alpine Entomology 8: 29-34

DOI: 10.3897/alpento.8.115588

Authors: Alan Oggier, Christophe Debonneville, Marco Conedera, Olivier Schumpp, Attilio Rizzoli

Abstract: ‘Candidatus Phytoplasma ulmi’ (Ca. P. ulmi) belongs to the ribosomal subgroup 16SrV-A and is associated with dieback, shoot proliferation and yellows disease on various Ulmus spp. Other plant species, such as Carpinus betulus and Prunus spp. have also been reported infected by the same pathogen. In 2021, in the frame of research activities focused on grapevine’s Flavescence dorée (FD), one specimen of Orientus ishidae - an East Palearctic leafhopper that was identified as an alternative vector of FD phytoplasmas - was found harboring Ca. P. ulmi in southern Switzerland. No phytoplasmas were detected in plant samples taken in the same location. Orientus ishidae has already been reported to be able to acquire diverse phytoplasmas associated with other plant diseases, such as Peach X-disease. This is the first report of Ca. P. ulmi in Switzerland, as well as in O. ishidae. Ca. P. ulmi may potentially be present in the wild compartment of the Swiss Pre-alpine and Alpine range, but no dedicated survey has so far been conducted. In the case of O. ishidae, this finding highlights the broad affinity of such a species for the acquisition of several phytoplasmas. This calls for a further investigation regarding its potential role as a vector on various pathosystems of agronomic importance.

Ants of Kamchatka: checklist, DNA-barcoding and key (Hymenoptera, Formicidae) https://alpineentomology.pensoft.net/article/114185/ Alpine Entomology 8: 19-28

DOI: 10.3897/alpento.8.114185

Authors: Sämi Schär

Abstract: Kamchatka is a remote volcanic peninsula in the sub-arctic Far East of Russia. Its myrmecofauna has been scientifically addressed several times. However, previous species lists are contradictory in part and a modern study seems to be lacking. Based on literature review, I conclude that 12 species and 4 genera (Camponotus, Formica, Leptothorax and Myrmica) of ants may be native to Kamchatka. Of those, 9 were found in the field, 3 having a Holarctic, 3 a trans-Palearctic and 3 an East Palearctic distribution. Most species diversity was found at mid-elevations, in pine shrubs and mixed forests, while deciduous forests and open habitats at lower altitudes were surprisingly species poor. DNA-barcoding was performed for 57 specimens/9 species. Genetic diversity (COI) was low for 8/9 species, with the exception of Leptothorax acervorum, for which all samples were of a different haplotype and 2 haplogroups were identified. For the encountered Holarctic and trans-Palearctic species, closely related haplotypes (<0.7% raw distance) occur in Europe and/or North America. Some Formica ants were morphologically atypical, with workers partially resembling those of F. fusca, while gynes identified as F. lemani. Morphometric analysis and DNA-barcoding suggested that all these specimens belong to a single species, F. lemani. Standard images for all specimens and an illustrated key to the worker caste are provided.

The Psyllinae (Hemiptera, Psyllidae) from Gunung Kinabalu (Malaysia, Sabah) https://alpineentomology.pensoft.net/article/113873/ Alpine Entomology 8: 1-17

DOI: 10.3897/alpento.8.113873

Authors: Daniel Burckhardt

Abstract: Five species of Psyllinae are recognised from Gunung Kinabalu, all previously unknown, and are formally described and named: Cacopsylla graciliforceps sp. nov., C. kinabaluensis sp. nov., C. myrsines sp. nov., C. photiniae sp. nov. and Psylla cirrita sp. nov. Another species similar to P. cirrita remains undescribed due to lack of sufficient material. Two Philippine species closely related to C. kinabaluensis are transferred to Cacopsylla as Cacopsylla aranetae (Miyatake, 1972), comb. nov. and Cacopsylla bakeri (Crawford, 1919), comb. nov. (both from Psylla). Three of the Cacopsylla species probably represent Palaearctic faunal elements (Cacopsylla graciliforceps, C. myrsines and C. photiniae). Host information is available only for Cacopsylla myrsines and C. photiniae, viz. Myrsine dasyphylla (Primulaceae) and Photinia davidiana (Rosaceae), respectively. Myrsine has not been previously reported as host genus of Psylloidea. The five new species bring the number of known Psylloidea species from Gunung Kinabalu to 22. The biogeographic relationships found in the flora, i.e. Oriental elements predominate at lower altitudes, and Himalayan and Australian elements are dominant at altitudes above 2500 m, are reflected in the psyllid fauna (Oriental 4 spp.; Australian 13 spp., Himalayan 3 spp.; unknown 2 spp.). Of the 22 species known from Gunung Kinabalu, 18 are only known from there. This high number is probably only partly due to endemism and is partly due to insufficient knowledge of the psyllid fauna of Borneo and of the tropics in general.

Annotated checklist of the Swiss bees (Hymenoptera, Apoidea, Anthophila): hotspots of diversity in the xeric inner Alpine valleys https://alpineentomology.pensoft.net/article/112514/ Alpine Entomology 7: 219-267

DOI: 10.3897/alpento.7.112514

Authors: Christophe Praz, Andreas Müller, Dimitri Bénon, Mike Herrmann, Rainer Neumeyer

Abstract: We present a checklist of the Swiss bees and provide information on the distribution of every bee species in all 26 Swiss cantons. 632 species are reported, including the European honeybee Apis mellifera Linnaeus, 1758 and the exotic species Megachile sculpturalis Smith, 1853. Species richness in each canton was correlated with the canton area, with the four largest cantons hosting the highest number of species. Bee diversity hotspots were located in some Alpine inner valleys characterized by a dry and warm climate due to the rain shadow effects of surrounding mountains. These hotspots are mostly located in the steppe-like habitats of the Valais and Graubünden cantons. They host diverse wild bee communities which include a unique assemblage of submediterranean faunal elements and subalpine species. In addition, these habitats host rare species with strongly disjunct distributions in Europe, further stressing the conservation priority of these habitats for wild bee conservation. Intensive faunistic surveys performed in the last 20 years have revealed that about 20 bee species, either previously unknown for Switzerland or which had disappeared from the country for several decades, have colonised areas close to the borders of France and Italy. Most of these new or reappeared species were observed in the warmest area of the country and presumably colonized or recolonized the country from neighbouring regions following global warming. Lastly, DNA barcodes are presented for 394 specimens, including for many species so far not represented in the BOLD database. The taxonomic status of numerous unclear taxa is briefly discussed based on combined genetic and morphological analyses.

Planning insect surveys in alpine ecosystems https://alpineentomology.pensoft.net/article/110958/ Alpine Entomology 7: 201-204

DOI: 10.3897/alpento.7.110958

Authors: Jérôme Pellet

Abstract: Most biological survey programs rely on multi-species inventories (e.g. birds, amphibians, butterflies, dragonflies). These programs usually rely on multiple visits during pre-defined time windows. The implicit goal of this popular approach is to maximize the observed species richness. Here, we present a novel method to optimize the timing of survey windows using a framework maximizing the detectable species pool. We present a proof of concept using 20 years of entomological records in Switzerland using butterflies, dragonflies, and grasshoppers. The general framework presented can potentially be applied to a wide range of biological survey schemes. It offers a new practical tool for adaptive entomological monitoring under climate change.

Taxonomic study of the alpine carabid beetle Nebria (Falcinebria) taketoi Habu, 1962 (Coleoptera, Carabidae) https://alpineentomology.pensoft.net/article/109855/ Alpine Entomology 7: 185-194

DOI: 10.3897/alpento.7.109855

Authors: Kôji Sasakawa

Abstract: The carabid beetle Nebria taketoi Habu, 1962 is endemic to the high-altitude mountains of Honshu, Japan; due to its rarity, it is one of the least taxonomically studied species among Japanese Nebria. This study taxonomically revised N. taketoi based on morphological comparisons, mainly of the endophallus in males, and geometric morphometrics of the pronotum, a taxonomically useful external character. Specimens previously identified as N. taketoi were found to belong to at least two species: N. taketoi, with a currently confirmed distribution in the northern Hida Mountains (type locality: Mikurigaike, Mount Tateyama), and N. kobushicola sp. nov. from the Okuchichibu and Yatsugatake mountains (type locality: Mount Kobushigatake). Species identities in populations from other localities could not be determined, as male specimens for endophallus examinations were unavailable. However, some populations may consist of species distinct from N. taketoi and N. kobushicola, based on their distribution and morphometric features. Based on comparative morphology of the endophallus, N. kobushicola shares features more similar to N. niohozana Bates, 1883 and N. dichotoma Sasakawa, 2020 than to N. taketoi.

Annotated checklist of the Hydrophiloidea of Switzerland (Coleoptera) https://alpineentomology.pensoft.net/article/111147/ Alpine Entomology 7: 167-184

DOI: 10.3897/alpento.7.111147

Authors: Vivien Cosandey, Yannick Chittaro, Andreas Sanchez

Abstract: Access to large, high-quality databases is one of the major needs in biodiversity studies. Faunistical data are essential but are often scarce and have to be compiled from various sources. On the basis of more than 30,000 occurrences obtained from specimens held in museum and private collections, as well as from literature data, we present the first updated checklist of the Swiss species of Hydrophiloidea (Georissidae, Helophoridae, Hydrochidae, Hydrophilidae, and Spercheidae) since 1900. In total, 105 species are retained as part of the Swiss fauna, while 16 species, which were recorded from Switzerland in the past, are excluded from this list, either due to insufficient documentation or because their records were based on misidentified material. Cercyon alpinus, Cercyon castaneipennis, Cercyon tatricus, Helophorus montenegrinus, Megasternum immaculatum, Pachysternum capense, and Paracymus scutellaris are recorded for the first time in Switzerland. This work is a further step towards the comprehension of the whole Swiss beetle fauna.

Micro-endemism pattern and Wolbachia infection of Quedius obliqueseriatus (Coleoptera, Staphylinidae), a montane rove beetle endemic of the North-Western Caucasus https://alpineentomology.pensoft.net/article/111214/ Alpine Entomology 7: 153-166

DOI: 10.3897/alpento.7.111214

Authors: Angesom Gebremeskel, Maria Salnitska, Valeria Krivosheeva, Alexey Solodovnikov

Abstract: We conducted an integrative taxonomic study of a forest floor dwelling montane rove beetle Quedius obliqueseriatus Eppelsheim, 1889. It is one of many endemic species of the North-Western Caucasus, a region considered a global biodiversity hotspot. Examination of the morphological characters in 93 specimens of Q. obliqueseriatus and phylogenetic assessment of the COI barcode for 28 of them, revealed that this species in fact consists of two distinct (p-distance of 4.0%) allopatric lineages, western and eastern. They subtly differ in the structure of the aedeagus, which was not noticed in the previous revision of this species. Nuclear DNA markers (H3, ITS1, ITS2, Wg and 28S) sampled in both lineages, did not show any divergence. Variation of the non-genitalic morphological characters, such as body size or coloration, is continuous across both lineages. Discovery of microendemic lineages within an endemic rove beetle species highlights how little is understood about the patterns and drivers of endemism in arthropods of the North-Western Caucasus. We refrained from the description of a new species due to shortage of data from the area where newly discovered western and eastern lineages meet. As Q. obliqueseriatus was found to be largely infected with Wolbachia, we gave a review of this infection among insects and other arthropods and its impact on speciation. Finally, we described our method of removal of the Wolbachia COI amplicon by endonuclease restriction enzyme in order to get the desired beetle amplicon from infected specimens.

Abstract: Cloeon vanharteni Gattolliat & Sartori, 2008 was newly discovered in the framework of our study of Ephemeroptera in the Draa basin, located in the southern region of the High Atlas in Morocco. This discovery is rather unexpected as the species was never reported outside the Arabian Peninsula and Levant; it is thus the first record for the Maghreb. The identification was based on morphological evidence and confirmed by the mitochondrial COI barcode.

Are yellow dung flies domesticated cow dung specialists? https://alpineentomology.pensoft.net/article/107649/ Alpine Entomology 7: 135-141

DOI: 10.3897/alpento.7.107649

Authors: Wolf U. Blanckenhorn, Dieter Burkhard

Abstract: The theory of niche differentiation implies some extent of specialization of species with regard to key resources, notably food. Coprophagous (dung-eating) insect larvae play a critical role in the decomposition of livestock dung in modern and traditional agricultural grasslands. The yellow dung fly (Scathophaga stercoraria L.; Diptera: Scathophagidae) is one of the largest, most common and abundant dung decomposers on pastures in cold-temperate regions across the entire northern hemisphere. As this fly is often associated with domesticated cattle or dairy cows, which are commonly kept for human nutrition worldwide (beef, milk, cheese, etc.), it is sometimes suspected to be a cow dung specialist. However, yellow dung flies are regularly active on and around other dung types, and must have reproduced on dung of wild vertebrates before the domestication of cattle. We therefore experimentally studied the performance of yellow dung fly larvae on dung of various large domestic vs. wild mammals (cow, horse, wild boar, red deer) in the laboratory in Switzerland. Larval performance in terms of juvenile survival, egg-to-adult development time, growth rate, and final adult body size, the major life history indicators of individual reproductive success, did not vary greatly among the various dung types tested. Thus, yellow dung flies can successfully reproduce on multiple types of mammal (vertebrate) dung, wild and domestic, and are therefore dung generalists rather than specialists. We conclude that yellow dung flies are common in European low- and highlands because they could plastically shift to dung of common herbivorous livestock after their domestication without losing the ability to reproduce on dung of common wild mammals.

A review of the Chrysolina species – subgenus Stichoptera Motschulsky, 1860 – in Switzerland, with notes on distribution, conservation and preimaginal stages (Coleoptera, Chrysomelidae) https://alpineentomology.pensoft.net/article/105937/ Alpine Entomology 7: 69-82

DOI: 10.3897/alpento.7.105937

Authors: Christoph Germann, Michael Geiser, Matthias Borer

Abstract: The species of the subgenus Stichoptera occurring in Switzerland are revised, based on a combination of literature data, old museum specimens and recent material. Four species, one with two subspecies, Chrysolina kuesteri (Helliesen, 1912), Ch. latecincta latecincta (Demaison, 1896), Ch. latecincta norica (Holdhaus, 1914), Ch. rossia (Illiger, 1802) and Ch. sanguinolenta (Linnaeus, 1758) are confirmed to occur in Switzerland, while Ch. gypsophilae (Küster, 1845) has to be excluded from the Swiss fauna due to insufficient evidence. Errors and unclarities in the older literature are discussed. Ch. kuesteri was found abundantly in central Valais, allowing some notes on its larval biology. Larvae of the alpine Ch. latecincta are also illustrated, along with notes on its habitat and some past and present distribution records. Illustrations for all Swiss members of the subgenus, as well as distribution maps with all confirmed records, are provided.

New species of Labiobaetis Novikova & Kluge from New Guinea (Ephemeroptera, Baetidae): a never-ending story of diversity https://alpineentomology.pensoft.net/article/106089/ Alpine Entomology 7: 83-134

DOI: 10.3897/alpento.7.106089

Authors: Thomas Kaltenbach, Laurent Vuataz, Jean-Luc Gattolliat

Abstract: Investigations of material collected partly in 1999 and mainly between 2006 and 2016 in New Guinea, mostly along the high, central mountain chain of the island, further increased our knowledge of the diversity of the genus Labiobaetis Novikova & Kluge on this island. Previously, 37 species were reported from New Guinea. We have identified six new species using a combination of morphology and genetic analysis (COI). They are described and illustrated based on their larvae. Five of the six new species belong to the group petersorum, which is endemic to the island. Additionally, Labiobaetis xeniolus Lugo-Ortiz & McCafferty is also assigned to this group. The morphological characterisation of the group petersorum is enhanced, and a key to all species of this group is provided. Complementary descriptions and remarks to the morphology of known species of the group petersorum are provided. Additionally, a genetic analysis (COI) including most species and several additional Molecular Operational Taxonomic Units (MOTUs) of the group petersorum is discussed. One of the new species belongs to the group vitilis. The morphological characterization of this group is slightly enhanced, and the obtained COI sequence was added to the genetic analysis of the group petersorum. The total number of Labiobaetis species worldwide is augmented to 162.

Prey handling and feeding habits of the snail predator Licinus depressus (Coleoptera, Carabidae) https://alpineentomology.pensoft.net/article/103164/ Alpine Entomology 7: 63-68

DOI: 10.3897/alpento.7.103164

Authors: Bruno Baur, José D. Gilgado, Armin Coray

Abstract: Carabid beetles of the tribe Licinini use their asymmetric mandibles to open the shells of land snails. Prey handling of large snails has been described in a few Licinini species. We observed for the first time how a male of Licinus depressus (Paykull, 1790) opens the shells of small prey snails (Chondrina arcadica (Reinhardt, 1881)) and eats their soft bodies. The beetle holds the conical snail shell with its forelegs and breaks the wall of the right-hand coiled shell. In doing so, the beetle rotates the shell counter-clockwise opening it stepwise along the dorsal part of the whorls towards the apex. After some bites, the beetle interrupts the opening process and begins to feed on the snail’s soft tissue. Then the beetle continues to break up the shell, shortly after which there is another feeding phase. The alternating sequence of shell breaking and feeding ends after 2 to 2.5 whorls when the beetle can no longer hold the prey’s remaining intact shell. We compare this previously unknown way of prey handling with the reported predatory behaviour in large snails by other Licinini species. Our observations confirm the high plasticity of predatory behaviour in Licinini beetles.

Laufkäfer und ihre Habitatpräferenzen entlang eines Höhentransekts von 2100 bis 2500 m ü. M. oberhalb der Alp Flix in den Schweizer Alpen (Coleoptera, Carabidae) https://alpineentomology.pensoft.net/article/102534/ Alpine Entomology 7: 57-62

DOI: 10.3897/alpento.7.102534

Authors: Marie Lüdeke, Christoph Germann, Matthias Jentzsch

Abstract: Während einer Saison im Jahr 2020 wurden in den östlichen Zentralalpen der Schweiz im Gebiet Sur, Alp Flix, bodenlebende Makroarthropoden mittels Barberfallen erfasst. Hauptziel war es, entlang eines ausgewählten Höhentransekts von 2100 bis 2500 m ü. M. die vorhandene Biodiversität zu erfassen. Entlang des Bergbaches Ava dallas Tigias wurden von Juni – November 2020 an sieben Standorten je drei Barberfallen aufgestellt und durchgehend betrieben. Vorliegend werden die Carabidae vorgestellt. Durch Berechnungen von Ähnlichkeitindices wurden deren Habitate innerhalb des untersuchten Höhentransekts abgegrenzt. Es konnten 393 Laufkäferindividuen aus 21 Arten erfasst und bestimmt werden. Sieben Arten wurden erstmals für die Alp Flix nachgewiesen. Davon sind die seltene Amara nigricornis und Leistus montanus rhaeticus besonders hervorzuheben. Aus den Berechnungen konnten drei Habitate der Laufkäfer im Transekt unterschieden werden: subalpines Grünerlengebüsch mit halbschattiger und mäßig feucht-frischer Ausprägung; alpines Habitat mit starker Krautschicht und frischer bis trockener Ausprägung und ein kurzrasiger hochalpiner Lebensraum mit xerothermer Ausprägung.

Three alien bark and ambrosia beetles (Coleoptera, Curculionidae, Scolytinae) new to Switzerland https://alpineentomology.pensoft.net/article/103269/ Alpine Entomology 7: 45-55

DOI: 10.3897/alpento.7.103269

Authors: Andreas Sanchez, Yannick Chittaro, David Frey, Bärbel Koch, Doris Hölling, Eckehard G. Brockerhoff, Beat Ruffner, Miloš Knížek

Abstract: Identifying alien species is important to ensure the early detection of biological invasions and survey shifts in species distributions in the context of global change. Here, we report on three alien bark and ambrosia beetles newly detected in Switzerland: Cyclorhipidion distinguendum (Eggers, 1930), C. pelliculosum (Eichhoff, 1878), and Hypothenemus eruditus (Westwood, 1834). These species were recorded for the first time during a comprehensive survey of saproxylic beetles accross major forest types and along an altitudinal gradient during the entire growing season in the southern Alps, in the canton of Ticino. Their local abundance and number of occurrences accross different lowland forest habitats, including alluvial forests of national importance, indicates that all three species are already naturalized. Given their polyphagy, it is likely that all three species will become more extensively distributed across Switzerland, with a yet unknown environmental impact.

The female of Megacraspedus peslieri Huemer & Karsholt, 2018 (Lepidoptera, Gelechiidae), a new case of brachyptery in alpine Lepidoptera https://alpineentomology.pensoft.net/article/103981/ Alpine Entomology 7: 37-44

DOI: 10.3897/alpento.7.103981

Authors: Peter Huemer

Abstract: Megacraspedus peslieri was described from the Pyrenees in 2018 and subsequently also discovered at a few localities in the northern Cottian Alps (Italy). The hitherto unknown female was collected in these localities after a targeted search. As with some other representatives of the genus, the female is flightless and shows a strikingly strong reduction of the wings (brachyptery). Whereas the forewings are significantly shortened and narrowed, the hindwings are strongly reduced. Both the external morphology and the genitalia of the female are described and illustrated in detail, together with previously unpublished photographs of live adults of both sexes. The identification of specimens from the Alps as well as of the male and female were determined by means of a DNA barcode comparison with the holotype.

The hidden diet – examination of crop content reveals distinct patterns of pollen host use by Central European bees of the genus Hylaeus (Hymenoptera, Colletidae) https://alpineentomology.pensoft.net/article/102639/ Alpine Entomology 7: 21-35

DOI: 10.3897/alpento.7.102639

Authors: Andreas Müller

Abstract: Masked or yellow-faced bees of the genus Hylaeus (Colletidae) differ in their mode of pollen transportation from most other bees in that they ingest the pollen directly on the flowers and carry it back to the nest inside the crop located in the anterior half of the metasoma. Due to this hidden mode of pollen transportation, the examination of pollen collected by Hylaeus females requires the dissection of the metasoma. Although this method has never been applied in Europe, the great majority of the Central European Hylaeus species were supposed to be pollen generalists based on observations of flower visits. The microscopical analysis of pollen removed from 30 crops each of 36 Central European Hylaeus species revealed that the proportion of species exhibiting an exclusive or strong preference for pollen from a single plant taxon is much higher than hitherto assumed and that the current assumption of the genus Hylaeus to largely consist of pollen generalists is wrong. Nineteen of the 36 species examined are strictly or largely dependent on a single plant taxon for collecting pollen, such as Apiaceae (n = 11 species), Rosaceae (n = 3), Reseda (Resedaceae) (n = 2), Allium (Amaryllidaceae) (n = 1), Asteraceae (n = 1) and Melilotus (Fabaceae) (n = 1). The 36 Hylaeus species examined collected pollen from the flowers of 31 plant families, of which the Apiaceae and Rosaceae (particularly Potentilla and Rubus) were by far the most important contributing almost 60% to the pollen host spectrum of the entire genus. The comparison between pollen host spectrum and flower visiting records showed that the pollen generalists use the flowers of the Asteraceae as nectar rather than pollen sources, corroborating earlier findings that the digestion of Asteraceae pollen requires physiological adaptations to cope with its unfavourable or protective properties. In summary, the patterns of pollen host use by bees of the genus Hylaeus do not substantially differ from those of other Palaearctic bee taxa despite the masked bees’ unusual habit to ingest the pollen directly on the flowers and to transport it inside their body back to the nest.

Inventory and pattern of distribution of mayflies (Insecta, Ephemeroptera) in the Draa river basin, southern Morocco https://alpineentomology.pensoft.net/article/96436/ Alpine Entomology 7: 13-20

DOI: 10.3897/alpento.7.96436

Authors: Mokhtar Benlasri, Nils Kaczmarek, Majida El Alami, Mohamed Ghamizi, Elisabeth Berger

Abstract: The Draa river basin is located south of the High Atlas Mountain rangee in Morocco. The Ephemeroptera (mayflies) fauna of its three sub-basins: the High, Middle, and Lower Draa are poorly known. This study contributes to the knowledge of Ephemeroptera and its distribution in relation to environmental parameters in this area. The larvae of Ephemeropteran species were collected during six field campaigns in 17 sites using a Surber sampler. A total of thirteen species belonging to ten genera and five families were identified. among which seven taxa were recorded for the first time in the southern Atlas area: Baetis maurus, Baetis rhodani, Cheleocloeon dimorphicum, Cloeon simile, Procloeon stagnicola, Labiobaetis neglectus and Oligoneuriopsis skhounate. The limits of distribution of most species can be explained by the increase in water temperature and electrical conductivity especially at lower altitudes.

On the occurrence of relict populations of Pytho abieticola J. R. Sahlberg, 1875 in Switzerland (Coleoptera, Pythidae) https://alpineentomology.pensoft.net/article/98799/ Alpine Entomology 7: 1-11

DOI: 10.3897/alpento.7.98799

Authors: Yannick Chittaro, Andreas Sanchez, Alexander Szallies, Martin M. Gossner, Thibault Lachat

Abstract: Several adults and larvae of Pytho abieticola were discovered in 2021 and 2022 at three different localities in two regions of Switzerland, the Jura mountains and the Swiss National Park in the Eastern Alps. This very rare saproxylic beetle has not been detected in Switzerland so far. Considered a relict of primeval forests, it is in strong decline or has already disappeared from large areas of Central Europe. The isolated Swiss populations are the westernmost in its distributional range. Information on the ecology and distribution of P. abieticola in Switzerland and Europe is provided and criteria to distinguish P. abieticola from the congeneric and syntopic P. depressus are defined.

In Memoriam: Dr. Jacques Derron – agronome et entomologiste (1945–2022) https://alpineentomology.pensoft.net/article/98192/ Alpine Entomology 6: 153-154

DOI: 10.3897/alpento.6.98192

Authors: Stève Breitenmoser

Abstract: C’est un vendredi, le 29 juillet 2022, que Jacques nous a quitté subitement dans sa 77ème année.Jacques Derron, né le 16 septembre 1945 au Vully, a effectué la majorité de sa carrière à Agroscope, sur le site de Changins, dans le service d’entomologie dont il prit la tête jusqu’à sa retraite en 2008.Issu d’une famille d’agriculteurs, Jacques grandit dans le Vully au bord du Lac de Morat où tout petit il s’émerveille déjà devant les batraciens et autres insectes qu’il observe dans sa région. Il accomplit sa scolarité au Vully, à Fribourg et à Neuchâtel où il obtient la maturité scientifique.Il choisit ensuite d’étudier l’agronomie à l’EPFZ où il est très vite attiré par l’entomologie et séduit par la production intégrée. C’est ainsi qu’il consacre son travail de diplôme à la lutte biologique contre la Mouche de la cerise. Il part ensuite, avec son épouse Monique, également ingénieur agronome, pour l’île de São Tomé (Golfe de Guinée). Pendant trois ans, il y effectue des recherches sur l‘entomofaune dans les plantations de cacao et y découvre, entre autres, de nouvelles espèces dont toute une série de coccinelles, parmi lesquelles Nephus derroni et Thea moniqueae. Ces recherches aboutissent à sa thèse de doctorat défendue en 1977: «Approche écologique de l’entomofaune des cacaoyères de São Tomé», sous la direction du Prof. Dr. V. Delucchi, Institut d’Entomologie EPFZ.La même année, Jacques intègre le Service phytosanitaire du canton de Genève où il se consacre notamment à la jaunisse nanisante de l’orge et ses vecteurs, à savoir les pucerons. A cette époque, il s’intéresse déjà beaucoup à la thématique des seuils d’intervention contre les ravageurs des cultures. Ceci afin de pouvoir offrir aux agriculteurs un outil décisionnel permettant de savoir si une intervention phytosanitaire dans les cultures est justifiable et rentable.Après cette période genevoise, Jacques postule à Agroscope, appelé encore Station fédérale de recherches agronomiques de Changins. Il y est engagé en janvier 1980 dans le Service d’entomologie. Il travaille alors sur de nombreux thèmes, notamment les questions épidémiologiques liées aux vecteurs de virus dans les pommes de terre et les céréales, la recherche de solution aux dégâts d’insectes du colza et les premiers cas de résistances aux insecticides, l’élaboration de seuils d’intervention et la participation active à la lutte biologique à l’aide des Trichogrammes contre la pyrale du maïs. Cette dernière, s’avère plus que jamais d’actualité avec la recherche d’alternatives durables dans la gestion des bioagresseurs des plantes. De ces travaux découlent de nombreux échanges avec des collègues au niveau national, notamment avec les interlocuteurs cantonaux, l’interprofession, les firmes, les agriculteurs, tout comme à l’international avec notamment le projet Euraphid. Pendant plusieurs années il donne, avec des collègues de divers domaines comme la phytopathologie, des cours sur la production intégrée aux étudiants d’agronomie à l’EPFZ. Il est un des membres fondateurs de la Société suisse de Phytiatrie qui se charge de l’étude des facteurs contribuant à la conservation et à l‘amélioration de la santé des plantes.Parallèlement à cette thématique «d’insectes ravageurs des cultures», Jacques avait bien compris que pour trouver des solutions phytosanitaires, il fallait comprendre le système dans son ensemble, c’est-à-dire l’étude synécologique dans l’espace agroenvironnemental. Il a donc étudié les échanges entre espèces, notamment les relations entre auxiliaires et ravageurs, ainsi que la biodiversité dans la zone agricole. Il prit part aux projets de mise en place et d’évaluation des premières surfaces de promotion de la biodiversité (appelée jadis surfaces de compensation écologique) avec ses collègues de Reckenholz et de nombreux partenaires dont l’OFAG, Agridea (SRVA), le Fibl, le WSL, la Station ornithologique suisse, les Universités de Bâle et Berne. Cela l’a conduit à étudier la faune carabique des surfaces cultivées ainsi que des milieux semi-naturels. Il participa d’ailleurs au récent travail de terrain pour la réactualisation de la Liste rouge des carabes sous l’égide d’Info Fauna/CSCF. Arrivé à la retraite, il se passionne pour les champignons, encore un monde … sans fin, qu’il va étudier sans relâche. Mais comme tous les chemins mènent à l’entomologie, Jacques faisait de belles découvertes de coléoptères mycétophages ou fongicoles trouvés dans des champignons qu’il me faisait partager. Pour l’anecdote, je me souviens, il y a peu, qu’il m’avait envoyé le plus petit coléoptère existant en Europe, à savoir Baranowskiella ehnstromi, trouvé dans un champignon lignicole sur saule.Jacques a publié de nombreux articles scientifiques sur la thématique de la protection des plantes et de l’entomologie. Il a aussi formé de nombreux apprentis laborantins et suivis des travaux de diplômes et thèses de doctorat. Il était membre de la Société suisse de Phytiatrie, de la Société suisse d’entomologie, des Sociétés de mycologie de Fribourg et de La Côte. Au moment de son décès, il était impliqué dans le projet «Inventaire des Champignons de la Grande Cariçaie».Jacques était un grand scientifique, toujours intéressé à comprendre le monde qui nous entoure. Il était également un amoureux des voyages, tout particulièrement des îles volcaniques (en souvenir de São Tomé), qu’il visitait avec son épouse et leurs deux filles. Il appréciait aussi grandement la lecture, notamment les traités historiques et géopolitiques, ainsi que la musique classique. Pour moi, Jacques était avant tout un homme généreux avec qui il faisait bon discuter et partager de bons moments d’amitié. Jacques, mon ami, tu vas nous manquer.

Eryngiofaga perrara sp. nov. (Hemiptera, Psylloidea) from Mount Pilatus (Obwalden), a new species of a genus previously unknown from Switzerland or the Alps https://alpineentomology.pensoft.net/article/97595/ Alpine Entomology 6: 147-151

DOI: 10.3897/alpento.6.97595

Authors: Daniel Burckhardt

Abstract: Eryngiofaga perrara sp. nov. is described, diagnosed and illustrated from two adult specimens found on Mount Pilatus (Switzerland, Obwalden). The new species is morphologically most similar to E. matura (Loginova, 1972), a species from Mongolia, from which it differs in the light genal processes and in details of the terminalia. Eryngiofaga consists of 13 previously described species of which five occur in Central and Western Europe. Up to now, the genus was not known from Switzerland or the Alps. The host plant of E. perrara remains unknown, but Bupleurum ranunculoides L. (Apiaceae) is a likely candidate.

Annotated checklist of the Coccinellidae (Coleoptera, Coccinelloidea) of Switzerland https://alpineentomology.pensoft.net/article/89476/ Alpine Entomology 6: 111-127

DOI: 10.3897/alpento.6.89476

Authors: Andreas Sanchez, Yannick Chittaro

Abstract: An updated checklist of the Swiss species belonging to the family Coccinellidae is presented and briefly discussed. This checklist includes 81 species (82 taxa including the subspecies) and is based on 33'976 occurrences obtained from the identification of specimens held in museum and private collections, as well as from records taken from the literature. Exochomus oblongus Weidenbach, 1859, Hyperaspis peezi Fürsch, 1976, Hyperaspis pseudopustulata Mulsant, 1853, Nephus bisignatus (Fürsch, 1984), Rhyzobius forestieri (Mulsant, 1853), Scymniscus anomus (Mulsant & Rey, 1852) and Scymnus doriae Capra, 1924 are recorded for the first time in Switzerland. In parallel, Chilocorus similis (P. Rossi, 1790), Bulaea lichatschovii (Hummel, 1827), Ceratomegilla rufocincta rufocincta (Mulsant, 1850), Coccinella undecimpunctata undecimpunctata Linnaeus, 1758, Chnootriba elaterii (P. Rossi, 1794), Henosepilachna vigintioctopunctata (Fabricius, 1775), Hyperaspis quadrimaculata (Redtenbacher, 1843), Scymnus marginalis (P. Rossi, 1794) and Novius cardinalis (Mulsant, 1850) were recorded from Switzerland in the past but are excluded from this list, either due to insufficient documentation or because they represent isolated cases of introductions of non-indigenous species that never became established in Switzerland.

DOI: 10.3897/alpento.6.86806

Authors: Serguei V. Triapitsyn, Armin Coray, Paul F. Rugman-Jones

Abstract: A fairyfly (Hymenoptera, Mymaridae) Cleruchus breviclava Triapitsyn & Coray, sp. nov. is described and illustrated. The new species is an egg parasitoid of the invasive Cis chinensis Lawrence (Coleoptera, Ciidae) in Antrodia xantha fungus (Polyporales, Fomitopsidaceae) in Basel, Switzerland; it is also known from low mountains in Germany and Switzerland. Supporting data on the “barcoding” region of the mitochondrial cytochrome c oxidase subunit I gene, as well as separate regions of nuclear ribosomal RNA, the D2 region of 28S and the internal transcribed spacer 2, provide strong evidence of conspecificity of the morphologically variable macropterous and strongly brachypterous individuals of C. breviclava. Macropterous females of the new species are most similar to those of C. detritus Bakkendorf, also known from Switzerland. New records are provided for some other species of Cleruchus Enock in Europe. A key to both sexes of the described European species of the genus is given.

Sudden collapse of xylophilous bee populations in the mountains of northern Utah (USA): An historical illustration https://alpineentomology.pensoft.net/article/93676/ Alpine Entomology 6: 77-82

DOI: 10.3897/alpento.6.93676

Authors: Vincent J. Tepedino, Frank D. Parker

Abstract: A scarcity of studies of the dynamics of wild bee populations hampers conservation efforts by bee ecologists and conservationists. Present limited information suggests that bee populations are highly unpredictable from year-to-year. Here we present an historical data set from nine sites replicated in 1984 and 1985 that demonstrates extreme between-year variability in numbers for 19 xylophilous bee species. Sixteen of those species produced far fewer nests in 1985, and 13 species in 1985 produced less than a third the number of nests produced in 1984. We argue that the 1985 collapse was not due to semivoltinism, i.e., the absence of morphs that require two years to mature, or to excessive sampling in 1984, but to a record cold period from January to March 1985 which likely killed most diapausing bees. Such events illustrate the dynamism of wild bee populations and thereby the large number of years needed to establish statistically significant population trends. We suggest that the current emphasis by bee conservationists to promote widespread surveillance monitoring programs is misguided and that funds are more effectively spent on hypothesis-driven targeted monitoring and on actions to actually reclaim degraded wild bee habitat.

Der Fremdling im Therapiegarten – Cis chinensis (Coleoptera, Ciidae) und sein Umfeld https://alpineentomology.pensoft.net/article/86494/ Alpine Entomology 6: 83-95

DOI: 10.3897/alpento.6.86494

Authors: Armin Coray, David A. Marques, Petr Vlček

Abstract: Samples of the tree fungus Antrodia xantha were collected on Pinus strobus in the therapy garden of the UPK campus (University Psychiatric Clinics) in Basel in summer 2021. The samples contained an alien Ciidae species new to Switzerland: Cis chinensis Lawrence, 1991, a species otherwise mainly known as a storage pest of commercially dried fungi. The adults and larvae of the Basel population are described and illustrated. When comparing the size of the adults of the two sample series collected two weeks apart, statistically significant differences were found. It appears that the above-average temperatures in June 2021 favoured the size of the second group. A number of (4–)5 larval stages are postulated for larval development. As an endoparasitoid of the eggs of C. chinensis, an unknown Mymaridae of the genus Cleruchus was found. Noteworthy was an unusually heavy infestation of Ciidae by phoretic mites (Histiostomatidae). During follow-up surveys in early 2022, additional individuals of C. chinensis were also found on the fruitbodies of other fungi growing in the immediate vicinity of the site where the population of the species was initially observed on A. xantha. A list of all Ciidae detected on the UPK campus is provided, and the spectrum of host-fungi of C. chinensis is discussed.

Description of the female of Platycheirus altomontis Merlin & Nielsen in Nielsen, 2004 (Diptera, Syrphidae) with notes on the occurrence and hilltopping behaviour of rare French montane and Alpine Syrphidae https://alpineentomology.pensoft.net/article/81676/ Alpine Entomology 6: 65-76

DOI: 10.3897/alpento.6.81676

Authors: Frank Van de Meutter

Abstract: A focused search in very high (2500–3200 m asl) Alpine mountain tops in France resulted in the discovery of the very rare Alpine-endemic syrphid Platycheirus altomontis Merlin & Nielsen in Nielsen, 2004, including its hitherto unknown female. A description of the female is given and further complemented with behavioural observations of this species with special reference to hilltopping. Additional records and behavioural observations are provided for rare and new species for the French fauna from the montane and Alpine habitat with focus on species of high altitude (>2750 m) and hilltopping behaviour. The species Rohdendorfia alpina Sack 1938 is new to France and was observed in large numbers at scree slopes above 2750 m and males were found sitting at hilltops up to 3200 m. Hilltopping behaviour of Syrphidae was observed over the whole altitudinal range visited, and multiple species engaged in this behaviour even at above 3000 m. Hilltopping appears to be more common in some genera (e.g. Parasyrphus and Pipizella) than in others and may be linked to specific phenotypes in some species. The latter was observed for the species Cheilosia melanura (Becker, 1894) of which at high hilltops much smaller males were found than at lower altitudes.

In these lotic beetles, we find cryptic diversity that highlights the need for geographically denser sampling combined with the use of an intergrative taxonomic approach to unravel the true diversity and biogeography of these beetles. We describe three new species: P. intania sp. nov. from the northern Bird’s Head Peninsula, P. kirana sp. nov. from the southern Bird’s Head as well as P. febrina sp. nov. which is more widespread on the Bird’s Head. Philaccolilus ameliae weylandensis is elevated to species rank, as Philaccolilus weylandensis stat. nov.

Periscelis (Myodris) haennii sp. nov., a new species of Periscelididae (Diptera) from Ticino, Switzerland, with a new key to European species of the subgenus https://alpineentomology.pensoft.net/article/85391/ Alpine Entomology 6: 39-49

DOI: 10.3897/alpento.6.85391

Authors: Lucia Pollini Paltrinieri, Jindřich Roháček

Abstract: A new Periscelididae species, Periscelis (Myodris) haennii sp. nov., is described from Losone near Locarno, Canton Ticino (Southern Switzerland). It has been found during a biodiversity survey using attractant traps in a Querco-Castagnetum forest. This new species is closely related and very similar to P. (M.) annulata (Fallén, 1813) occurring syntopically in the same traps. Interestingly, also P. (M.) piricercus Carles-Tolrá & Verdugo Páez, 2009 co-occurred with these species; consequently, all European species of the subgenus Myodris Lioy, 1864 were found in this locality. A new illustrated key to males of these species is presented. The DNA sequences of the barcoding region of COI for all these species are given.

 Zoophthora giardii Bałazy and Conidiobolus gustafssonii Bałazy (Fungi, Entomophthorales), two entomopathogens new for Switzerland https://alpineentomology.pensoft.net/article/83182/ Alpine Entomology 6: 19-23

DOI: 10.3897/alpento.6.83182

Authors: Siegfried Keller

Abstract: Meconema meridionale Costa (Orthoptera, Tettigoniidae) infected with Zoophthora giardii Bałazy (Entomophthorales, Entomophthoraceae) were collected at five localities in the northern half of Switzerland. At one of these sites, the fungus caused epizootics in two subsequent years. Symptoms and morphological data coincide with those given by Bałazy who found the fungus on Meconema thalassinum De Geer. Conidiobolus gustafssonii Bałazy (Entomophthorales, Ancylistaceae) was found on a single Ectobius vittiventris Costa (Blattodea, Ectobiidae). Symptoms and dimensions of the primary conidia correspond with the original description given by Bałazy who found the fungus on Ectobius lapponicus L. The two fungi are new for Switzerland and Meconema meridionale and E. vittiventris represent new hosts for these pathogens.

Modeling the distribution of coprophagous beetle species in the Western Swiss Alps https://alpineentomology.pensoft.net/article/83730/ Alpine Entomology 6: 25-38

DOI: 10.3897/alpento.6.83730

Authors: Vivien Cosandey, Olivier Broennimann, Antoine Guisan

Abstract: Coprophagous beetles are essential for fecal matter removal and are thus considered key ecosystem services providers. Yet, our knowledge of these beetles’ distribution and ecology remains very limited. Here, we used Species Distribution Models (SDM) to investigate the species-environment relationships (i.e. their niche) and predict the geographic distribution of coprophagous beetles in the Western Swiss Alps. We used our own sampled data and existing national data from the Swiss faunal database to calibrate, for each species, a regional and a national SDM respectively. In both models, the best predictors were temperature and rock cover proportion, while a soil characteristic (∂13C) indicating its organic content and texture was important in the regional models and precipitations in the Swiss models. The model performed better for species specialized on low or high altitudes than for generalist species occurring in a large altitudinal range. The model performances were neither influenced by the size, nor by the nesting behavior (laying eggs inside or below the excrements) of the species. We also showed that species richness decreased with altitude. This study opens new perspective for a better knowledge of coprophagous beetle’s ecology and a useful tool for their conservation in mountain regions.

Two new high Andean species of Liodessus diving beetles from Venezuela (Coleoptera, Dytiscidae, Bidessini) https://alpineentomology.pensoft.net/article/79598/ Alpine Entomology 6: 7-12

DOI: 10.3897/alpento.6.79598

Authors: Michael Balke, David T. Bilton, Mauricio García, Ángel L. Viloria, Adrián Villastrigo, Lars Hendrich

Abstract: Two new species of the diving beetle genus Liodessus Guignot, 1939 are described from high mountain regions in Venezuela: Liodessus meridensis sp. nov. from Laguna de Mucabají, Mérida and L. venezuelensis sp. nov. from Laguna de Mucabají and below Pico Bolívar, Mérida. We delineate the species using morphological characters such as male genital structure and beetle size, shape and color. Mitochondrial cox1 sequence data provided an additional character source. Both new species occur at altitudes above 3,500 m and were collected in shallow water at the edge of high-altitude ponds.

Lack of genetic structure suggests high connectivity of Parnassius phoebus between nearby valleys in the Alps https://alpineentomology.pensoft.net/article/80405/ Alpine Entomology 6: 1-6

DOI: 10.3897/alpento.6.80405

Authors: Andreas Jaun, Hans-Peter Wymann, Kay Lucek

Abstract: The spatial scale of intraspecific genetic connectivity and population structure are important aspects of conservation genetics. However, for many species these properties are unknown. Here we used genomic data to assess the genetic structure of the small Apollo butterfly (Parnassius phoebus Fabricius, 1793; Lepidoptera: Papilionidae) across three nearby valleys in the Central Swiss Alps. One of the valleys is currently used for hydropower production with future plans to raise the existing dam wall further. We found no significant genetic structure, suggesting a currently high connectivity of this species in our studied region.

Five years of Alpine Entomology, the international journal on mountain insects https://alpineentomology.pensoft.net/article/78033/ Alpine Entomology 5: 123-124

DOI: 10.3897/alpento.5.78033

Authors: Thibault Lachat, Oliver Y. Martin

Abstract: Similar to many other species groups, insects are affected by the biodiversity crisis caused by land use and climate changes, over or under use of resources, pollution, and invasive alien species (IPBES 2019). After the famous Krefeld study, which highlighted a loss of 75% of the insect biomass over the last 27 years in protected areas in Germany (Hallmann et al. 2017), further scientific articles and reviews have been published on this topic (e.g., Seibold et al. 2019; Wagner 2020). Nowadays, it is obvious, that the diversity and biomass of insects are strongly threatened globally. Nevertheless, not all insect populations are decreasing. Some thermophilous species can benefit from climate change and hence expand their population size and their distribution (e.g., Roth et al. 2021). There are also examples of increasing insect populations due to successful conservation measures (e.g., Walter et al. 2017). A comprehensive recent study published in a Swiss Academic Report (Widmer et al. 2021) concluded that conservation measures are urgently needed to avoid dramatic losses of insects and the valuable ecosystem services they provide. This is necessary for all activity sectors such as agriculture, forestry, and energy production. Among other measures, this report recommends an intensification of species monitoring and research activities in entomology, and an improvement in knowledge transfer. Our journal, Alpine Entomology, fulfills this goal extremely well. As an open-access journal, we aim at publishing inter alia research and review articles, short communications and checklists on arthropods not only from the Alps but also from other mountainous regions. In doing so, we contribute to the dissemination of knowledge on insects to a broad audience. For example, more than twenty articles published in Alpine Entomology since 2017 have acquired more than 2’000 unique views. To improve the international impact and scientific quality of Alpine Entomology, we can now count on our recently formed editorial board. The board members will act as ambassadors for our journal outside of Switzerland, as well as support us in our strategic decisions. Our Editorial board is currently composed of the following people: Prof. Dr. Thibault Lachat, Editor in chief, Bern University of Applied Sciences Dr. Oliver Martin, President of the Swiss Entomological Society, ETH Zurich Dr. Yves Basset, Smithsonian Tropical Research Institute, Panama Prof. Dr. Inon Scharf, Tel Aviv University PD Dr. Seraina Klopfstein, Natural History Museum, Basel Prof. Dr. Lyubomir Penev, Managing Director and Founder of Pensoft Publishers We are open to extending this board by inviting a few additional members, and especially hope to recruit international researchers working in regions not currently represented. A few weeks ago, we launched our first topical collection, a step that should also help to increase the attractivity of our journal. This collection is focused on arthropods associated with aquatic ecosystems in mountainous regions. Aquatic ecosystems and especially running waters represent some of the most impacted environments on the planet. Furthermore, aquatic invertebrates are key indicators of global or local changes, and many aquatic ecosystems are closely linked to mountains as they originate in them. With this open collection, Alpine Entomology now provides authors with an opportunity to submit manuscripts based on already available data with clear evidence for changes/trends in aquatic arthropods (even where sampling designs were not initially conceived for this goal). Such studies would be highly relevant to improving our understanding of developments concerning arthropod populations and knowledge of aquatic species. With this initiative, we aim to provide a platform for scientists to publish research articles or short notes on trends and/or changes in biogeography, species community or distribution, as well as behavior, or morphology of aquatic arthropods from mountainous regions. The editors of this collection (Jean-Luc Gattolliat and Dávid Murányi) will be inviting authors to submit their manuscript and will offer a fee waiver for invited contributions. The topical collection is also open to relevant additional contributions (for details see https://alpineentomology.pensoft.net/special_issues). Over the next months, we plan to launch further topical collections and therefore hope to offer attractive avenues for researchers to publish their results in our journal. The editorial board will be involved in evaluating suggestions for future topics, as well as recruiting new topics in a targeted fashion. After five years of existence, Alpine Entomology has already surmounted different challenges. Since 2019, our journal has been indexed in Emerging Sources Citation by Clarivate Analytics and since 2020, we are also indexed by Scopus. One of our goals for the next years will be to obtain an impact factor from Clarivate. This would provide a clear signal that our journal is well established and recognized in the scientific community. To reach this goal, we need to recruit and secure a consistent flow of manuscripts aiming at ca. 20–25 published papers per year. Of course, the quality of our published articles must also be guaranteed. Fortunately, for this we can continue to count on the strong support of our expert subject editors and the numerous reviewers. Here, we would like to take the opportunity to thank all those involved for their essential contributions to our journal over the years since its creation.

Protokoll der Jahresversammlung der Schweizerischen Entomologischen Gesellschaft vom 5. März und 21. Juni 2021 via Videokonferenz https://alpineentomology.pensoft.net/article/77433/ Alpine Entomology 5: 119-122

DOI: 10.3897/alpento.5.77433

Authors: Marc Neumann

Abstract: Aufgrund der anhaltenden Corona-Pandemie musste die Jahresversammlung leider auf einen Tag reduziert werden und ohne physische Präsenz stattfinden. Sie wurde daher per Videokonferenz abgehalten. Der Präsident Oliver Martin hatte dafür ein Meeting via Zoom organisiert, das reibungslos ablief. Trotz der erschwerten Umstände konnte ein interessantes Vortragsprogramm für die Jahresversammlung zusammengestellt werden. Den Themenschwerpunkt bildete die experimentelle Forschung mit Hymenopteren, jedoch aus ganz unterschiedlichen Fachgebieten. Das Programm startete mit dem Hauptvortrag von Yuko Ulrich, Professorin an der ETH Zürich, zum Thema Sozialverhalten und Krankheitsdynamik bei Ameisen. Darin gab sie einen Einblick, wie im Labor soziale Interaktionen und die Mechanismen der Entstehung von Arbeitsteilung untersucht werden. Als Modellorganismus diente die räuberische Ameisenart Ooceraea biroi, die keine Königinnen ausbildet. Stattdessen vermehren sich alle Individuen parthenogenetisch, was den Faktor der genetischen Varianz in Experimenten deutlich reduziert. Mittels Kameras über mehreren Dutzend Ameisenkolonien und Farbcodes auf den Tieren konnte das Verhalten und der Aufenthaltsort (im Nest oder ausserhalb des Nests) jedes Individuums analysiert werden. Dann wurde der Einfluss der Koloniegrösse, sowie der Mischung von Genotypen und Körpergrössen innerhalb einer Ameisengruppe auf das Verhalten der Tiere untersucht. Abschliessend berichtete Frau Ulrich über die neueste Forschung mit experimentell infizierten Ameisen. Von Pilzsporen befallene Tiere werden intensiver von Artgenossen betreut, wodurch ihre Überlebensrate stark steigt. In zukünftigen Studien sollen die genannten Untersuchungen über mehrere Generationen von Ameisen hinweg ausgedehnt werden. Folgende fünf Vorträge wurden gehalten: ● Social behaviour and disease dynamics in clonal ant colonies. Yuko Ulrich, ETH Zürich ● Defensive symbionts protect aphids from parasitoid wasps depending on stable genotype-by-genotype interactions. Elena Gimmi, Eawag / ETH Zürich ● Megachile sculpturalis Smith, 1853 (Hymenoptera: Megachilidae), an Asian wild bee populates Europe. Julia Lanner, Universität für Bodenkultur Wien / Universität Bern ● Homemade or take away: Where do the cuticular hydrocarbons of parasitoid wasps come from? Corinne Hertäg, ETH Zürich ● Entwicklungsbiologische Ursachen sexueller Merkmale bei Mistkäfern: Wie macht man lange Beine? Patrick Rohner, Indiana University Der ETH Zürich sei für das Zurverfügungstellen des Videokonferenzraums herzlich gedankt.

On some Ctenarytaina species (Hemiptera, Psylloidea) from Gunung Kinabalu (Malaysia, Sabah) https://alpineentomology.pensoft.net/article/77751/ Alpine Entomology 5: 107-113

DOI: 10.3897/alpento.5.77751

Authors: Daniel Burckhardt

Abstract: Gunung Kinabalu is famous for its exceptionally diverse fauna and flora, rich in endemism. An example is the psyllid genus Ctenarytaina that is represented by four, apparently endemic species. Here two new Ctenarytaina species, C. lienhardi sp. nov. and C. smetanai sp. nov., are described from Gunung Kinabalu. The new taxa are diagnosed, illustrated and their relationships to other species in the genus are discussed. Ctenarytaina daleae Burckhardt is redescribed. The species develops on Leptospermum species (Myrtaceae) and not Syzygium as previously suggested.

Relict populations of Lyonetia ledi Wocke, 1859 (Lepidoptera, Lyonetiidae) from the Alps indicate postglacial host-plant shift to the famous Alpenrose (Rhododendron ferrugineum L.) https://alpineentomology.pensoft.net/article/76930/ Alpine Entomology 5: 101-106

DOI: 10.3897/alpento.5.76930

Authors: Peter Huemer, Jürg Schmid

Abstract: Lyonetia ledi Wocke, 1859 (Lyonetiidae), was hitherto considered as a boreal species with a circumpolar distribution pattern and relict populations in isolated peat bogs north-east of the Alps (Austria, Czech Republic, Germany). In Europe it is known as a leaf-miner on Rhododendron tomentosum Stokes ex Harmaja (Ericaceae) as the primary host-plant and also Myrica gale L. (Myricaceae). The first record of L. ledi from the Swiss Alps on Rhododendron ferrugineum L., the famous Alpenrose, indicates an ancient host-plant switch during postglacial periods when R. tomentosum and R. ferrugineum shared habitat in the prealps. Conspecificity with northern populations is supported by the adult morphology and supplementing DNA barcodes (mtDNA COI gene). L. ledi is the first obligatory leaf-mining species on R. ferrugineum. Details of the life-history and habitat are described and figured. The record finally substantiates the probability of an autochthonous population in Carinthia (Austria), from where the species was recently published as new to the Alps.

Female accessory gland fluid promotes sperm survival in yellow dung flies https://alpineentomology.pensoft.net/article/68501/ Alpine Entomology 5: 95-100

DOI: 10.3897/alpento.5.68501

Authors: Karin Thüler, Wolf U. Blanckenhorn, Paul I. Ward, Stefan Lüpold, Luc F. Bussière

Abstract: Female and male reproductive traits co-evolve through pre- and post-copulatory sexual selection and sexual conflict. Although males typically transfer many sperm during copulation, only a small proportion reach the fertilization site because females often actively or passively reduce sperm number in their reproductive tract. Males may transfer accessory substances to protect their ejaculates against female selective processes, which benefits males but can harm females. In turn, females may use accessory gland fluids to control paternity or sperm storage. Female yellow dung flies (Scathophaga stercoraria) have paired accessory glands that produce fluids involved in fertilization and egg laying. One proposed function for these fluids is spermicide. Alternatively, female accessory gland fluid may help keep sperm alive to avoid fertilization failure or encourage sperm competition. Using yellow dung flies, we investigated the interaction of female accessory gland fluid with sperm in vitro. Significantly more sperm remained alive when exposed to accessory gland fluid compared to buffer only (63% vs. 44%). We conclude that female accessory gland fluid in yellow dung flies can help nourish rather than kill male sperm, although selective nourishment of sperm is as consistent with cryptic female choice as is selective spermicide.

DOI: 10.3897/alpento.5.70640

Authors: Daniel Burckhardt, Dalva L. Queiroz

Abstract: Mitrapsylla rupestris sp. nov., associated with Poiretia bahiana C. Mueller (Fabaceae, Faboideae, Dalbergieae), is described, diagnosed and illustrated. The new species is morphologically similar to M. aeschynomenis, M. aurantia, M. cubana and M. didyma from which it differs in details of the terminalia and the host plant. Poiretia constitutes a previously unknown psyllid host. As its host, Mitrapsylla rupestris sp. nov. is probably endemic to rock habitats of the Espinhaço Range in eastern Brazil. These rock habitats display a high species diversity but are seriously threatened by human activities. More research on these habitats is urgently needed to design efficient conservation strategies.

An updated checklist of the Cantharidae and Lycidae of Switzerland (Coleoptera, Elateroidea) https://alpineentomology.pensoft.net/article/67808/ Alpine Entomology 5: 77-94

DOI: 10.3897/alpento.5.67808

Authors: Yannick Chittaro, Andreas Sanchez, Michael Geiser

Abstract: An updated checklist of the Swiss species belonging to the families Cantharidae and Lycidae, is presented and briefly discussed. This checklist includes 106 species and is based on over 26’000 occurrences obtained from the identification of specimens held in museum and private collections, as well as from records taken from the literature. Cantharis liburnica Depoli, 1912, C. paradoxa Hicker, 1960, Malthinus rubricollis Baudi di Selve, 1859 and Malthodes umbrosus Kiesenwetter, 1871 are recorded from Switzerland for the first time. Two species previously recorded from Switzerland (Malthodes montanus Kiesenwetter, 1863, M. boicus Kiesenwetter, 1863) are excluded from this list, as those records were based on misidentified material.

Energetic underpinnings of yellow dung fly mating success in the field https://alpineentomology.pensoft.net/article/68153/ Alpine Entomology 5: 61-67

DOI: 10.3897/alpento.5.68153

Authors: Wolf U. Blanckenhorn

Abstract: Foraging provides the basis for animal reproduction, but requires energy and time to be sustained, entailing a trade-off. Whereas females should maximize their time foraging for resources, males should minimize their foraging time by optimizing time budgets to maximize their access to mating partners. Mark-resight field studies are difficult and hence uncommon for small insects. Yellow dung flies (Scathophaga stercoraria L.) abound on pastures in cold-temperate regions across the northern hemisphere. Adult flies lick nectar from flowers for energy, but require small insect prey to produce eggs and sperm. Males wait for females around fresh cow dung, but at one point also need to replenish their energy and/or sperm reserves in the surrounding vegetation. Their foraging time budgets should depend on their body size, nutritional energy reserves, availability of sperm, competitor and female density. Marked male dung flies whose nutritional status was experimentally manipulated – water only (null control); water + sugar (energy replenishment); or water, sugar + Drosophila prey (energy and sperm replenishment) – were repeatedly observed on an experimental pasture for an entire day. Both nutrient types were expected to increase the mating success of especially large males. The total number of resighted males seen copulating was lowest for water-treated flies. Mating success was positively related to body size. The distance travelled between dung pats was greater for males fed sugar or prey and also increased with body size, while pat residence times decreased with size. No differences were found between the sugar- and prey-fed groups. Crucially however, there was no evidence in the field for a time budget or mating advantage of small males when nutrients were limited.

Rediscovery of Stactobia eatoniella McLachlan, 1880 (Trichoptera, Hydroptilidae) in Switzerland after more than seventy years https://alpineentomology.pensoft.net/article/67985/ Alpine Entomology 5: 55-60

DOI: 10.3897/alpento.5.67985

Authors: Laurent Vuataz, Pascal Stucki, Lucie Fauquet, Régine Bernard

Abstract: A specimen of Stactobia eatoniella, a hygropetric species of micro-caddisfly considered extinct in Switzerland, was discovered in the Morge in Valais in March 2020 during routine monitoring. This last instar larva in perfect condition is the first to be observed in Switzerland since 1944. Further research in the study area is needed to confirm the presence of a possible well-established population. This encouraging discovery should not hide the fact that two thirds of the micro-caddisfly species are on the Red List of threatened species of Switzerland, and that hygropetric habitats are both under-studied and highly endangered in Switzerland and worldwide.

Unraveling a complex problem: Dichrorampha velata sp. nov., a new species from the Alps hitherto confounded with D. alpestrana ([Zeller], 1843) sp. rev. = D. montanana (Duponchel, 1843) syn. nov. (Lepidoptera, Tortricidae) https://alpineentomology.pensoft.net/article/67498/ Alpine Entomology 5: 37-53

DOI: 10.3897/alpento.5.67498

Authors: Jürg Schmid, Peter Huemer

Abstract: Analysis of wing pattern, genital morphology and results of DNA barcoding indicates that the name Dichrorampha montanana sensu auct. actually comprises two species. D. alpestrana ([Zeller], 1843) sp. rev. is considered as senior synonym of D. montanana (Duponchel, 1843) syn. nov., and a lectotype is designated for the latter name to fix the identity. After thorough search for possible synonyms, Dichrorampha velata sp. nov. is described and differentiated morphologically and with DNA barcodes from D. alpestrana and adults and genitalia of both species are figured. Dichrorampha velata sp. nov. is restricted to the European Alps and adjacent regions whereas D. alpestrana is more widespread with likely arctic-alpine disjunction and records from the Alps and the northern part of Great Britain.

A fungal parasite selects against body size but not fluctuating asymmetry in Swiss subalpine yellow dung flies https://alpineentomology.pensoft.net/article/65653/ Alpine Entomology 5: 27-35

DOI: 10.3897/alpento.5.65653

Authors: Wolf U. Blanckenhorn

Abstract: Evidence for selective disadvantages of large body size remains scarce in general. Previous studies of the yellow dung fly Scathophaga stercoraria have demonstrated strong positive sexual and fecundity selection on male and female size. Nevertheless, the body size of flies from a Swiss study population has declined by ~10% 1993–2009. Given substantial heritability of body size, this negative evolutionary response of an evidently positively selected trait suggests important selective factors being missed. An episodic epidemic outbreak of the fungus Entomophthora scatophagae permitted assessment of natural selection exerted by this fatal parasite. Fungal infection varied over the season from ~50% in the cooler and more humid spring and autumn to almost 0% in summer. The probability of dying from fungal infection increased with adult fly body size. Females never laid any eggs after infection, so there was no fungus effect on female fecundity beyond its impact on mortality. Large males showed their typical mating advantage in the field, but this positive sexual selection was nullified by fungal infection. Mean fluctuating asymmetry of paired appendages (legs, wings) did not affect the viability, fecundity or mating success of yellow dung flies in the field. This study documents rare parasite-mediated disadvantages of large-sized flies in the field. Reduced ability to combat parasites such as Entomophthora may be an immunity cost of large body size in dung flies, although the hypothesized trade-off between fluctuating asymmetry, a presumed indicator of developmental instability and environmental stress, and immunocompetence was not found here.

First observation of an ant colony of Formica fuscocinerea Forel, 1874 invaded by the social parasite F. truncorum Fabricius, 1804 (Hymenoptera, Formicidae) https://alpineentomology.pensoft.net/article/67037/ Alpine Entomology 5: 23-26

DOI: 10.3897/alpento.5.67037

Authors: Rainer Neumeyer, Jürg Sommerhalder, Stefan Ungricht

Abstract: In the northern Alps of Switzerland we observed a mixed ant colony of Formica truncorum Fabricius, 1804 and F. fuscocinerea Forel, 1874 at the foot of a schoolhouse wall in the built-up centre of the small town of Näfels (canton of Glarus). Based on the fact that the habitat is favorable only for F. fuscocinerea and that F. truncorum is a notorious temporary social parasite, we conclude that in this case a colony of F. fuscocinerea must have been usurped by F. truncorum. This is remarkable, as it is the first reported case where a colony of F. fuscocinerea has been taken over by a social parasite. We consider the observed unusually small workers of F. truncorum to be a starvation form. This is probably due to the suboptimal urban nest site, as this species typically occurs along the edge of forests or in clearings.

Two males, one female: triplet-style mating behaviour in the Darwin wasp Xorides ater (Gravenhorst, 1829) (Hymenoptera, Ichneumonidae, Xoridinae) in the Swiss Alps https://alpineentomology.pensoft.net/article/64803/ Alpine Entomology 5: 15-22

DOI: 10.3897/alpento.5.64803

Authors: Mark R. Shaw, Madalene Giannotta, Andrés F. Herrera-Flórez, Seraina Klopfstein

Abstract: The Darwin wasp Xorides ater is a solitary idiobiont ectoparasitoid of wood-boring beetle larvae. It occurs across the Palaearctic, and in Switzerland seems to be restricted to areas above 980 m altitude. Very little is known about its biology and behaviour. We here report three separate instances of a female X. ater mating simultaneously with two males, observed on the same occasion on a Picea abies woodpile near Lenk, Switzerland. Only two copulae that involved one male and one female were observed at the same time, which might indicate that this mating mode is rather common in X. ater. We illustrate our observations with photo and video material and compare it to mating behaviour known from other species of Darwin wasps.

Hypera temperei Hoffmann, 1958 – first discovery of the western alpine element in the Swiss Alps with biological details, and new morphological insights (Coleoptera, Curculionidae) https://alpineentomology.pensoft.net/article/61597/ Alpine Entomology 5: 5-13

DOI: 10.3897/alpento.5.61597

Authors: Christoph Germann

Abstract: Since its description based on a single female from the Maritime Alps in France, no other localities of this enigmatic alpine species have become public. In a scree slope in the Valais at high montane altitude Hypera temperei Hoffmann, 1958 was discovered for the first time elsewhere, in Switzerland. The species’ biology is unravelled, its habitat is described, and photographs of the male, larvae and pupa are presented. The re-investigation of the species morphology revealed that Hypera temperei is closest to H. postica (Gyllenhal, 1813), and not to H. viciae (Gyllenhal, 1813) as previously supposed. A revision of specimens in collections revealed that H. temperei is distributed even more eastern in the alpine Arc in Grisons at high montane to high alpine altitudes. Hence the species shows a considerably wider distribution in the Alps than supposed before.

Tracking the spread of the northern bark beetle (Ips duplicatus [Sahlb.]) in Europe and first records from Switzerland and Liechtenstein https://alpineentomology.pensoft.net/article/53808/ Alpine Entomology 4: 179-184

DOI: 10.3897/alpento.4.53808

Authors: Beat Wermelinger, Doris Schneider Mathis, Miloš Knížek, Beat Forster

Abstract: The northern bark beetle (Ips duplicatus), in Europe originally restricted to northern countries, expanded its distribution range to eastern Europe in the 20th century and is now causing considerable damage in spruce forests. In the past decades its presence has been confirmed in several Central European countries. By means of pheromone traps and visual inspection of infested logs, in this study we demonstrate that I. duplicatus is also present in the Rhine valley in Switzerland and Liechtenstein. Breeding galleries with beetles and exit holes in an infested spruce log indicate that the trapped beetles had successfully developed in a local stand nearby. An inquiry addressed to European entomologists was carried out to obtain information and references concerning the year of the first record or mention of I. duplicatus in their respective countries. This information substantiated the expansion of its historical range to the southeast in the middle of the last century and clearly showed recent movement westward, with Switzerland and Germany currently the westernmost countries where this species occurs. This recent range expansion is likely attributed to the transport of infested timber. The economic significance of this expanding bark beetle species is discussed in view of its co-occurrence with the notorious pest species I. typographus.

Two new species of Liodessus Guignot, 1939 diving beetles from Northern Peru (Coleoptera, Dytiscidae, Hydroporinae) https://alpineentomology.pensoft.net/article/55139/ Alpine Entomology 4: 173-178

DOI: 10.3897/alpento.4.55139

Authors: Michael Balke, Yoandri S. Megna, Nilver Zenteno, Luis Figueroa, Lars Hendrich

Abstract: The diving beetles Liodessus altoperuensis sp. nov. and Liodessus caxamarca sp. nov. (Dytiscidae, Hydroporinae, Bidessini) are described from the high altitudes of the Puna regions of north western Peru. They occur in shallow and exposed mossy peatland puddles. We delineate the two species using structures such as male genitalia, beetle size, shape and colour pattern. Mitochondrial Cox1 data were also generated, and revealed clusters congruent with morphological evidence. Altogether fourteen Liodessus species are now known from the Andean region.

Unique nesting biology of Osmia ( Melanosmia) uncinata, a Palaearctic osmiine bee specialized on thick-barked conifers (Hymenoptera, Megachilidae) https://alpineentomology.pensoft.net/article/53489/ Alpine Entomology 4: 157-171

DOI: 10.3897/alpento.4.53489

Authors: Andreas Müller, Rainer Prosi, Stewart Taylor, Henning Richter, Mike Herrmann, Urs Weibel

Abstract: Osmia (Melanosmia) uncinata Gerstäcker is a Palaearctic megachilid bee distributed from temperate and northern Europe eastwards to the Russian Far East. The discovery of over 80 nests in Switzerland, southern Germany and Scotland enabled for the first time a closer investigation of its nesting biology and prompted the assessment of the species’ phenology, distribution and habitat. O. uncinata nested in self-excavated burrows inside the bark of both living trunks and dead stumps of Pinus sylvestris. The nests were excavated at a height of 10–220 cm above ground either on the underside of prominences of longitudinal bark ribs or inside beetle borings and extended more or less vertically upwards. They consisted of a single straight to slightly curved burrow with rarely one to three side burrows, had a total length of 1.2–12.0 cm and contained 1–6 brood cells. The brood cells, which faced downwards with the larval provisions being located in the upper cell half, were separated from each other by one-layered walls of chewed leaves (“leaf pulp”). The nests were sealed with a plug of 2–4 closely adjacent walls of leaf pulp. DNA metabarcoding of cell and plug walls revealed that Potentilla and Fragaria (Rosaceae) served as leaf pulp sources. Pre-imaginal mortality amounted to 77%, partly caused by brood parasites such as Sapyga similis (Sapygidae) and Cacoxenus indagator (Drosophilidae) or predators such as snakeflies (Raphidioptera). At low elevations, O. uncinata needs one year for its development and overwinters as imago inside the nest, whereas in the subalpine zone of the Alps it has a two-year cycle passing the first winter as prepupa and the second winter as imago. O. uncinata starts to emerge between the end of March at low elevations and the end of May at higher elevations qualifying as an early flying bee like the other European O. (Melanosmia) species. The distribution of O. uncinata in Central Europe and Scotland largely coincides with the occurrence of P. sylvestris. As in the pine, it extends over a wide altitudinal range from below 100 m up to 1900 m a.s.l. and encompasses dry and wet as well as warm and cold habitats including open pine forests, inner and outer forest edges dominated by pine and isolated pine groups. At a few locations in the subalpine zone of the Alps, O. uncinata occurs in the absence of P. sylvestris; here, the thick bark of Larix decidua serves as a substitute nesting substrate.

First record of Erasmoneura vulnerata Fitch, 1851 (Hemiptera, Cicadellidae, Typhlocybinae) in Switzerland https://alpineentomology.pensoft.net/article/53967/ Alpine Entomology 4: 151-156

DOI: 10.3897/alpento.4.53967

Authors: Attilio Rizzoli, Riccardo Battelli, Marco Conedera, Mauro Jermini

Abstract: The first record of Erasmoneura vulnerata Fitch, 1851 in Switzerland is reported. Specimens were collected in 2019 using yellow sticky traps during a Scaphoideus titanus monitoring campaign in vineyards in Ticino (Southern Switzerland). E. vulnerata is a grapevine pest that has recently been introduced to Europe, whose phytophagy causes detrimental damage to grapevine leaves. Its occurrence in this area has likely been favored by the ongoing suspension of insecticide treatments for the control of the S. titanus population, the vector agent of the “Flavescence dorée” phytoplasma in grapevines.

Rétablissement des communautés de libellules (Odonata) dans les tourbières du Jura neuchâtelois (Suisse) https://alpineentomology.pensoft.net/article/36290/ Alpine Entomology 4: 99-116

DOI: 10.3897/alpento.4.36290

Authors: Arnaud Vallat, Christian Monnerat, Sébastien Tschanz-Godio, Laurent Juillerat

Abstract: Les tourbières des Vallées de la Brévine et des Ponts-de-Martel ont perdu plus de 90% de leur surface au 20e siècle suite à l'exploitation industrielle de la tourbe. Les travaux de revitalisation entrepris entre 1996 et 2018 ont permis d'y augmenter le nombre de plans d'eau de 240 à 341, leur surface passant de 1.3 à 10.1 hectares. Dès 2005, les odonates ont fait l'objet de suivis réguliers dans plusieurs marais. En 2017 et 2018, un suivi exhaustif a permis de recenser 38 espèces. L'ensemble des données récoltées entre 1938 et 2018 concerne ainsi 52 espèces, soit plus des 2/3 de la faune de Suisse. Parmi elles, neuf figurent sur la Liste Rouge nationale. Les espèces inféodées aux hauts-marais profitent des mesures de revitalisation et voient leur nombre augmenter depuis 2005. Leucorrhinia pectoralis s'est ainsi implantée de manière spectaculaire dans 12 hauts-marais sur 15, alors que L. albifrons, l'une des libellules les plus rares de Suisse, se reproduit dans une tourbière ayant fait l'objet d'importantes revitalisations. De même, les découvertes d'Aeshna subarctica et de Ceriagrion tenellum laissent présager leur implantation dans la région d'étude. Fort de ce bilan positif, le canton de Neuchâtel prévoit de poursuivre son programme de revitalisations au moins pour les cinq prochaines années. Parallèlement, seule une gestion coordonnée des différents marais visant à garantir une offre variée en habitats permettra le maintien des espèces les plus exigeantes.

Création de nouvelles prairies dans le réseau écologique « La Frontière » VD et effets sur les orthoptères (Insecta: Orthoptera) https://alpineentomology.pensoft.net/article/46308/ Alpine Entomology 4: 117-128

DOI: 10.3897/alpento..46308

Authors: Stève Breitenmoser, Jean-Yves Humbert, Sylvie Viollier

Abstract: Le réseau écologique Paysage « La Frontière » situé à l’ouest du canton de Vaud est composé de près de 700 surfaces de promotion de la biodiversité (SPB) totalisant plus de 500 ha. Dans ce cadre, plus de 150 ha de nouvelles prairies naturelles, pour la plupart plantées de haies et d’arbres, forment la pièce centrale de l’infrastructure écologique de ce réseau. Elles remplacent des grandes cultures (terres assolées) et ont été mises en place par la méthode de l’enherbement direct (fleurs de foin). Les orthoptères et la mante religieuse (Mantis religiosa) ont été choisis comme bio-indicateurs pour évaluer la richesse spécifique et la vitesse de colonisation de ces nouvelles surfaces. Les relevés orthoptériques ont été effectués, entre 2014 et 2018, sur 33 nouvelles prairies et ont été comparés à 13 prairies naturelles anciennes extensives. En moyenne, le nombre d’espèces par prairie était de 9.3 (dont 1.7 sur la Liste rouge) dans les nouvelles prairies et de 11.5 (2.6) dans les prairies anciennes. Statistiquement, il n’y a aucune différence significative entre les deux types de prairies. Aucune corrélation entre le nombre d’années après la mise en place des nouvelles prairies et le nombre d’espèces recensées par prairie n’a été détectée, indiquant une colonisation rapide des nouvelles prairies. Parmi les espèces d’orthoptères cibles du réseau écologique cantonal, figurant également sur la Liste rouge, six sont présentes dans les prairies anciennes comme dans les nouvelles. Parmi ces dernières, Metrioptera bicolor et Euchorthippus declivus étaient présentes dans près de 60% des prairies. Les résultats montrent l’importance d’une répartition dense de prairies à la fois de bonne qualité (enherbement direct) et exploitée extensivement avec des zones refuges. Ils soulignent également l’importance des prairies anciennes et des aires naturelles protégées comme réservoirs pour la restauration de la biodiversité dans les paysages agricoles.

Integrative revision of the Caryocolum schleichi species group – a striking example of a temporally changing species concept (Lepidoptera, Gelechiidae) https://alpineentomology.pensoft.net/article/50703/ Alpine Entomology 4: 39-63

DOI: 10.3897/alpento.4.50703

Authors: Peter Huemer

Abstract: The taxonomy of the Palaearctic Caryocolum schleichi species group is revised, leading to a largely new species concept. Initially described as four different species (C. schleichi, C. arenariella, C. dianthella, C. improvisella), these taxa were later considered as subspecies. Recently the taxon C. arenariella was re-instated to species level without, however, revision of the remaining three subspecies. Analysis of DNA barcodes of the mtCOI (Cytochrome c Oxidase 1) gene of all four validly described taxa showed an unexpected pattern of genetic diversity. Careful re-examination of morphological traits, particularly male and female genitalia, fully supported this pattern, leading to the re-instatement of C. dianthella sp. rev. and C. improvisella sp. rev. as valid species and the description of three new species, all of them occurring in the Alps: C. messneri sp. nov. (Italy, Slovenia, Bulgaria, Greece), C. lamai sp. nov. (Italy, France) and C. habeleri sp. nov. (France, Switzerland, Germany). All species are described in detail and the adults and genitalia of both sexes are illustrated.

Review of the endemic New Zealand genus Arctesthes Meyrick (Lepidoptera, Geometridae, Larentiinae), with descriptions of two new range-restricted species https://alpineentomology.pensoft.net/article/33944/ Alpine Entomology 3: 121-136

DOI: 10.3897/alpento.3.33944

Authors: Brian H. Patrick, Hamish J.H. Patrick, Robert J.B. Hoare

Abstract: The genus Arctesthes Meyrick (Geometridae: Larentiinae: Xanthorhoini), endemic to the South Island of New Zealand, is revised. Four species are recognised, including two new species, as follows: Arctesthes catapyrrha (Butler, 1877), A. siris (Hudson, 1908), A. titanica sp. nov. and A. avatar sp. nov. All except A. catapyrrha are restricted to subalpine and alpine localities. Adults and genitalia are fully described and illustrated for all species; larvae of A. catapyrrha are also briefly described and illustrated. Only Arctesthes catapyrrha is widespread; A. siris is restricted to a few mountain ranges of Central Otago; A. titanica is only known from two wetland localities in the Von Valley of the Otago Lakes district, and A. avatar is only known from a few wetlands in a restricted area of north-west Nelson. The two new species are considered of very high priority for conservation.

Nesting in bark – the peculiar life history of the rare boreoalpine osmiine bee Osmia (Melanosmia) nigriventris (Hymenoptera, Megachilidae) https://alpineentomology.pensoft.net/article/34409/ Alpine Entomology 3: 105-119

DOI: 10.3897/alpento.3.34409

Authors: Andreas Müller, Rainer Prosi, Christophe Praz, Henning Richter

Abstract: Osmia (Melanosmia) nigriventris (Zetterstedt) is a predominantly boreoalpine megachilid bee species, whose biology is poorly known due to its pronounced rarity all over Central Europe. The discovery of 19 nests in the Grisons and Valais (Switzerland) allowed for the investigation of its nesting biology and prompted the assessment of the species’ host-plant spectrum, phenology and distribution. All nests were in thick bark pieces of Larix decidua, which lay in grassy vegetation on sun-exposed ground of open subalpine forests dominated by larch. The nests contained 1–26 brood cells constructed within one to several burrows tunneled out by the female bees with their specialized mandibles, which are distinctly stronger than those of related O. (Melanosmia) species known to nest in preexisting cavities or loose soil. The linearly arranged brood cells were separated from each other by three-layered partitions consisting of an interlayer of densely packed small bark particles sandwiched between two thin layers of chewed green leaves (“leaf pulp”). DNA metabarcoding of several nest plugs revealed that Potentilla (Rosaceae) and Helianthemum (Cistaceae) served as source of the leaf pulp. Anthrax anthrax (Bombyliidae) and Sapyga similis (Sapygidae) parasitized the brood cells of O. nigriventris as shown by DNA barcoding of prepupae overwintering in the host’s nests. O. nigriventris is mesolectic and harvests pollen almost exclusively on Fabaceae (e.g. Lotus, Hippocrepis), Ericaceae (Rhododendron, Vaccinium) and Cistaceae (Helianthemum). Depending on the altitude, O. nigriventris emerges from the beginning of May to the first decade of June and thus qualifies as an early flying bee active in spring and early summer similar to the other European O. (Melanosmia) species. It likely needs two years for its development in the subalpine zone of the Alps and overwinters as prepupa in the first and probably as imago in the second winter. O. nigriventris has a Holarctic distribution, its disjunct Palaearctic range encompasses the boreal zone from Scandinavia eastwards to the Russian Far East, the Caucausus, the Alps as well as scattered locations at lower altitudes throughout Central Europe, where it is regarded as a glacial relict and has probably suffered strong declines during the last decades.

Distribution of a residual population of the Dytiscid Graphoderus bilineatus (de Geer, 1774) in the Grande Cariçaie nature reserves, Switzerland https://alpineentomology.pensoft.net/article/30417/ Alpine Entomology 3: 83-91

DOI: 10.3897/alpento.3.30417

Authors: Aline Knoblauch, Antoine Gander

Abstract: Currently, the distribution of diving beetles in Switzerland is poorly known making it difficult to determine conservation priorities for species with small and/or declining populations. In order to establish conservation priorities, in 2018, we surveyed diving beetles of the genus Graphoderus in the Grande Cariçaie reserves with special consideration for the Red Listed G. bilineatus. While G. bilineatus and G. cinereus showed high habitat niche overlap, the distribution of G. bilineatus was limited to mainly one of the eight reserves. When comparing our results to available historical data, the habitat of G. bilineatus has likely diminished during the last 40 years. Our study provides the first comprehensive documentation of the distribution of Graphoderus species in the Grande Cariçaie. We further highlight the importance for improving the knowledge of G. bilineatus distribution in Switzerland to develop policy for conservation of this globally threatened species.

Checklist of ichneumonid parasitoid wasps in Switzerland (Hymenoptera, Ichneumonidae): 470 species new for the country and an appraisal of the alpine diversity https://alpineentomology.pensoft.net/article/31613/ Alpine Entomology 3: 51-81

DOI: 10.3897/alpento.3.31613

Authors: Seraina Klopfstein, Matthias Riedel, Martin Schwarz

Abstract: We here present the first comprehensive and validated species list of the parasitoid wasp family Ichneumonidae in Switzerland. The list includes 1,878 species and is based on both an extensive literature research and a review of all reliably identified specimens present in the major Swiss collections. Because of the incomplete taxonomic treatment of this largest hymenopteran family, we adopted a conservative approach, accepting only species that have been published recently and/or were identified by recognized experts. The subfamilies Adelognathinae, Brachycyrtinae, Diacritinae and Lycorininae are reported for the first time for the country, as are 470 of the 1,878 species. The true number of species of ichneumonids in Switzerland is probably much higher, given the incomplete revision of Swiss specimens and the fact that large areas of the country were studied very sparsely or not at all. The subalpine and alpine areas deserve special attention, as they show a higher ratio between the number of species per collected specimen; these areas should be the focus of intensified collecting efforts in the future. The current list may serve as a starting point for more extensive taxonomic and faunistic work on Ichneumonidae in Switzerland.

Fire and windthrow in forests: Winners and losers in Neuropterida and Mecoptera https://alpineentomology.pensoft.net/article/30868/ Alpine Entomology 3: 39-50

DOI: 10.3897/alpento.3.30868

Authors: Peter Duelli, Beat Wermelinger, Marco Moretti, Martin К. Obrist

Abstract: The mid-term impact of forest fires and windthrows on species compositions in the insect orders Neuroptera, Raphidioptera and Mecoptera was assessed in Swiss forests using standardized flight interception traps. For 50 species the abundances in intact control plots were compared to those in moderately or strongly disturbed forest stands. The catches were combined over four forest disturbance projects ranging from windthrows in alpine spruce forests and lowland deciduous forests to winter forest fires in Southern Switzerland and a large summer fire in southwestern Switzerland. As a result 82% of the 50 species benefited from the disturbance and became more abundant in the years after the fire or windthrow. More species (19) had their maximum abundance in intermediately disturbed plots than in heavily disturbed forests (17). Only 11 species mainly Hemerobiidae and Coniopterygidae peaked in the undisturbed forest stands. The species are listed per impact and ranked as winners (more than 66% specimens per treatment collected in disturbed forest plots) losers (more than 66% specimens per treatment in undisturbed forest plots) and indifferent species. An additional 29 species that were too scarce for an assessment are listed in Appendix 1. We conclude that for Neuropterida and Mecoptera catastrophic incidences are natural ecological events which create new habitats and by this foster their occurrence and abundance.

Hidden diversity in European bees: Andrena amieti sp. n., a new Alpine bee species related to Andrena bicolor (Fabricius, 1775) (Hymenoptera, Apoidea, Andrenidae) https://alpineentomology.pensoft.net/article/29675/ Alpine Entomology 3: 11-38

DOI: 10.3897/alpento.3.29675

Authors: Christophe Praz, Andreas Müller, David Genoud

Abstract: We revise the Alpine bee taxa related to Andrena bicolor (Fabricius, 1775), including A. montana Warncke, 1973 and A. allosa Warncke, 1975, the status of which has remained contentious. Phylogenetic analyses of one mitochondrial gene and one nuclear gene, as well as morphological examination reveal the presence of four Alpine species in this complex, one of which is new to science, A. amieti sp. n. This new species is widely distributed in the Alps from southern France throughout Switzerland, northern Italy and southern Germany to Austria; a single record is known from the Apennines. The type locality is located within the Unesco World Heritage site “Swiss Alps Jungfrau-Aletsch”. Two widely divergent mitochondrial lineages are found in sympatry in A. amieti sp. n.; the status of these lineages, which together form a paraphyletic unit from which A. allosa arose, is briefly discussed. We show that A. allosa, A. amieti sp. n. and A. montana are polylectic but that each species exhibits a distinct spectrum of pollen hosts: the univoltine A. allosa shows affinities for pollen of the early-blooming Alpine plant genus Crocus. A. amieti sp. n. is bivoltine and, as in A. bicolor, the summer generation exhibits a distinct preference for Campanulaceae, while the spring generation is widely polylectic. A. montana has a single generation in the summer and forages on a diversity of flowers such as Campanulaceae, Cistaceae and Caryophyllaceae. An identification key is presented for central European members of the subgenus Euandrena Hedicke, 1932. Lastly, the new Alpine species appears to represent the tip of the iceberg of substantial cryptic diversity in southern European Andrena (Euandrena): A. croatica Friese, 1887 is resurrected from synonymy with A. bicolor and treated as a valid species (stat. rev.), A. pileata Warncke, 1875, described as a subspecies of A. allosa, is elevated to species rank (stat. n.), and three additional unclear taxa are briefly described.

Temporal niche partitioning of Swiss black scavenger flies in relation to season and substrate age (Diptera, Sepsidae) https://alpineentomology.pensoft.net/article/28366/ Alpine Entomology 3: 1-10

DOI: 10.3897/alpento.3.28366

Authors: Patrick T. Rohner, Jean-Paul Haenni, Athene Giesen, Juan Pablo Busso, Martin A. Schäfer, Frank Püchel-Wieling, Wolf U. Blanckenhorn

Abstract: Understanding why and how multiple species manage to coexist represents a primary goal of ecological and evolutionary research. This is of particular relevance for communities that depend on resource rich ephemeral habitats that are prone to high intra- and interspecific competition. Black scavenger flies (Diptera: Sepsidae) are common and abundant acalyptrate flies associated with livestock dung decomposition in human-influenced agricultural grasslands worldwide. Several widespread sepsid species with apparently very similar ecological niches coexist in Europe, but despite their ecological role and their use in evolutionary ecological research, our understanding of their ecological niches and spatio-temporal distribution is still rudimentary. To gain a better understanding of their ecology, we here investigate niche partitioning at two temporal scales. First, we monitored the seasonal occurrence, often related to thermal preference, over multiple years and sites in Switzerland that differ in altitude. Secondly, we also investigate fine-scale temporal succession on dairy cow pastures. In accordance with their altitudinal and latitudinal distribution in Europe, some species were common over the entire season with a peak in summer, hence classified as warm-loving, whereas others were primarily present in spring or autumn. Phenological differences thus likely contribute to species coexistence throughout the season. However, the community also showed pronounced species turnover related to cow pat age. Some species colonize particularly fresh dung and are gradually replaced by others. Furthermore, the correlation between co-occurrence and phylogenetic distance of species revealed significant under-dispersion, indicating that more closely related species are frequently recovered at the same location. As a whole, our data suggests temporal niche differentiation of closely related species that likely facilitates the rather high species diversity on Swiss cattle pastures. The underlying mechanisms allowing close relatives to co-occur however require further scrutiny.
