Abstract: Oxytripia orbiculosa (Esper, 1800) is a noctuid with a trans-Palaearctic distribution whose presence in the Iberian Peninsula had sometimes been considered uncertain more than four decades after the initial recording of a single specimen in 1981. The discovery of a population in the Central Pyrenees, in the province of Huesca (Spain) through sampling conducted in 2023 and 2025, confirms a close ecological link with the orophilous endemism Xiphion latifolium Mill., which acts as the host plant of O. orbiculosa in high mountain meadows between 1400 and 1700 m altitude. Data on the biology of the species and its attraction to various types of artificial light are provided. Externally, the Iberian specimens differ from most populations of the rest of Europe in their somewhat larger average size and in their colour, which is notably darker, with less apparent whitish spots, markings and crosslines. However, we have not found any substantial differences in genital morphology or CO1 barcode. Interpopulation variability inferred from a molecular study using CO1 barcoding of the Eastern European populations, as well as isolation, reinforces the taxonomic identity of the Iberian population at the subspecific level. Therefore, we propose the name Oxytripia orbiculosa isolata Guerrero, Yela, Grundy, Rubio & Ortiz, 2026, ssp. nov.

Abstract: The Ponto-Caspian amphipod Chaetogammarus trichiatus was recorded for the first time in Lake Geneva. The identification of the collected specimens was established through morphological examination and independently confirmed by DNA barcoding based on the mitochondrial COI gene. The present observation in Lake Geneva is noteworthy, as C. trichiatus has only rarely been reported from lake ecosystems, most records originating from large rivers. In addition to addressing sampling aspects, we describe the habitat of C. trichiatus in Lake Geneva, detail the morphological identification criteria used to distinguish the species, and discuss the probable implications of this newly recorded species for the interpretation of previous findings in the lake.

Abstract: Lissomus arawak sp. nov. is described from montane mesic forest sites in Monseñor Nouel, Pedernales and Puerto Plata provinces of the Dominican Republic. This is the third species of the genus reported from the Greater Antilles and Hispaniola. It is distinguished by its highly convex and ovoid form, shining black integument, and appearing glabrous dorsally due to very short pubescence. Structurally it is more similar to Lissomus gagatinus Bonvouloir, 1859 and Lissomus impressifrons Bonvouloir, 1859 from Central America and South America indicating a probable second lineage of these beetles in the Greater Antilles.

Abstract: Two new species of the diving beetle genus Liodessus Guignot, 1939 are described from Costa Rica: Liodessus quetzalicus sp. nov. (central valley as well as the high-mountain Páramo region, 1,380–2,800 m) and L. cerrodelamuerte sp. nov. (> 3,000 m). The species are delineated based on morphological characters, including male genitalia as well as beetle size, shape and colour pattern. The habitats are described in detail. Altogether 18 species and 10 additional subspecies of Liodessus are now recorded from higher mountain regions in Central and South America.

Abstract: Aiyitioderus gen. nov. and A. montanus sp. nov. are described for the first time from the mountains of the Dominican Republic, Hispaniola. This species is similar to those of the heterostixus-group currently assigned to Heteroderes Latreille from mainland North America. The species is only known from higher elevations in mixed humid broadleaf forest to pine and cloud forest transitions. Aiyitioderus gen. nov. is the first endemic genus of Elateridae reported from the West Indies.

Abstract: Climate change is known to cause range shifts to higher elevations in mountainous regions. Butterflies are especially sensitive to changes in environmental conditions and their response to climate change has been extensively studied. However, the influence of habitats on the community composition and climate change responses of alpine butterflies has so far been widely neglected. In 2025, butterflies in the Swiss National Park (SNP) were surveyed using the semi-quantitative transect method. It was shown that habitat availability explained most of the variation in community composition, while elevation solely played a minor role and tended to act mostly in combination with habitats. Compared to previous butterfly surveys between 1998 and 2004 in the same area, the Community Temperature Index increased, indicating more warm-adapted communities, especially at the lower and medium parts of the examined elevational gradient. In 2025, species were found on average at an elevation 135 m higher than two decades earlier. The upward shift corresponded closely to the expected displacement of +140 m in elevation, suggesting butterflies keeping pace with local warming. The upslope displacement was especially pronounced for species restricted to a narrow range of habitats. The pronounced response of butterfly communities to global warming seems to cause a threat particularly to high-alpine species with a high degree of habitat specialisation. In this context, the habitat dependency of butterflies may have negative effects due to a mismatch of the elevational distribution of butterflies and their host plants and the ongoing transformation of alpine habitats but might as well be the basis for species conservation.

Abstract: Boletina kowarzi Stackelberg, 1943 (Diptera: Mycetophilidae) is recorded from Central Europe for the first time in nearly 150 years. The species was originally described based on a single specimen from Thuringia, Germany, collected in 1877, and has not been reported from Central Europe since. New material collected in the Bavarian Alps, Germany, has enabled a redescription and updated diagnosis of the species. The morphology of the male terminalia is documented in detail and illustrated together with the general habitus. Diagnostic characters confirm that B. kowarzi belongs to the species group centred around B. dubia, characterised by a two-branched gonostylus with elongated branches, but it is distinguished from related species by the structure of the inner gonostylar branch and the arrangement of spines on the cerci. DNA barcode data (COI), including diagnostic molecular combination (DMC), reveal pronounced genetic divergence between B. kowarzi and other examined congeners, supporting its distinct species status. The new specimens were collected in an old-growth forest remnant in the Bavarian Alps, characterised by abundant dead wood and a rich community of wood-inhabiting fungi. The discovery suggests that the species may persist in relic montane forests, although its ecological requirements remain poorly understood.

Abstract: Hispaniodirphia lemaireiana Rougerie & Herbin, 2006 is an endemic saturniid moth restricted to the montane pine forests of Hispaniola. Here we provide the first description of the female and the first detailed accounts of the larva (final instar) and pupa. Larvae were observed in Sierra de Bahoruco National Park (Dominican Republic) at 1400–2000 m a.s.l., feeding on the endemic pine Pinus occidentalis Sw. Pupae were recovered from the soil beneath host trees, without a cocoon, at depths up to 10 cm. Female variation is documented and compared with Hispaniodirphia plana Lemaire, 1999. These data represent the first host-plant association reported for Hispaniodirphia and contribute to the biological knowledge of Hemileucinae in Caribbean montane ecosystems.

Abstract: The European representatives of the erebid genus Setina Schrank, 1802 exhibit considerable intraspecific and interpopulation variability. In this study, their taxonomic status is reassesed using an integrative approach that combines a review of the existing literature, morphological examination, and analysis of mitochondrial DNA sequences from the protein-coding cytochrome c oxidase subunit I gene (COI5P). The major European lineages of Setina appear to form three species complexes: Setina irrorella (Linnaeus, 1758), including the subspecies flavicans (Geyer, 1836), distributed from Spain to European Russia; Setina roscida (Denis & Schiffermüller, 1775), including the subspecies cantabrica de Freina & Witt, 1985 and kuhlweini (Hübner, 1824), ranging from the Iberian Peninsula to central Siberia; and Setina aurita (Esper, 1787) which is currently regarded as restricted to the Alps.

Abstract: Zygentoma, encompassing silverfish and allies, are an ancient lineage of wingless insects, often associated with human environments in Central Europe. Knowledge in Switzerland on the distribution and ecology of both native and non-native species is very limited. This study summarizes the historic and current knowledge on the distribution and ecology of Zygentoma in Switzerland using a literature review, specimens’ collection, and citizen science observations submitted to iNaturalist.org and GBIF.org. We document three native species: Atelura formicaria Heyden, 1855, Lepisma saccharinum Linnaeus, 1758 and Ctenolepisma lineatum Fabricius, 1775 and three non-native, synanthropic taxa: Ctenolepisma longicaudatum Escherich, 1905 and Ctenolepisma phantasma Molero-Baltanás, Raphel, Mitchell & Jose, 2025 as well as the greenhouse-associated taxa Nicoletia phytophila Gervais, 1844. Synanthropic species seem to benefit from modern building designs and are now widespread. Climate change may further promote expansions into outdoor environments and enable new species to colonize Switzerland. The combination of cryptic, nocturnal behaviour, identification challenges, and a lack of systematic monitoring has resulted in significant knowledge gaps. Ongoing surveys, specimen collections, and the continued use of citizen science platforms are essential for tracking future changes in the distribution and community composition of Zygentoma in Switzerland.

Abstract: On the basis of more than 53,000 occurrences obtained from specimens held in museum and private collections, as well as from literature data, we present an updated checklist of the Swiss species of several families belonging to the superfamily Coccinelloidea (Alexiidae, Bothrideridae, Cerylonidae, Endomychidae, Latridiidae, Teredidae) and the superfamily Cucujoidea (Cucujidae, Erotylidae, Laemophloeidae, Monotomidae, Phloeostichidae, Silvanidae, Sphindidae). In total, 183 species are retained as part of the Swiss fauna, while 18 species, which were recorded from Switzerland in the past, are excluded from this list because of insufficient documentation, misidentified material, or isolated introductions of nonindigenous species. Fourteen species are recorded for the first time in Switzerland: Triplax collaris (Schaller, 1783), Triplax elongata Lacordaire, 1842 (both Erotylidae), Cryptolestes corticinus (Erichson, 1846) (Laemophloeidae), Corticaria alleni C. Johnson, 1974, Corticaria interstitialis Mannerheim, 1844, Corticaria orbicollis (Mannerheim, 1853), Corticarina cavicollis (Mannerheim, 1844), Latridius brevicollis (C. G. Thomson, 1868), Melanophthalma algirina Motschulsky, 1866, Melanophthalma parvicollis (Mannerheim, 1844), Melanophthalma rhenana Rücker & Johnson, 2007 (all Latridiidae), Rhizophagus oblongicollis Blatch & Horner, 1892 (Monotomidae), Psammoecus trimaculatus Motschulsky, 1858 (Silvanidae), and Teredus opacus Habelmann, 1854 (Teredidae). This work represents a further step toward a comprehensive understanding of the entire Swiss beetle fauna.

Abstract: Although Europe is the best-explored continent entomologically, major gaps remain, especially in alpine regions and within taxonomically challenging “dark taxa”, such as parasitoid wasps. I describe three new species of Darwin wasps from the Swiss Alps: Diadegma (Nythobia) davidmarquesi sp. nov., D. (Nythobia) mirum sp. nov., and D. (Nythobia) orophilum sp. nov. These species were discovered during a revision of Swiss natural history collections and are diagnosed using morphometric characters, microsculpture, and colour patterns, with comparisons to type material. One species appears to have a wider, possibly boreoalpine distribution, whereas the other two are currently known only from montane to alpine habitats in Switzerland. These findings increase the number of Diadegma species described from the European Alps to 13 and highlight this region as an important reservoir of undescribed Darwin wasp diversity. They further underscore the need for continued integrative taxonomic work, combining museum revision, targeted alpine sampling, and the collection of host data, to more fully document the hidden diversity and biogeographic importance of Europe’s alpine insect fauna.

Abstract: The diving beetle Rhantus procul sp. nov. is described from around 2,000 m a.s.l. at Mount Pompangeo in Central Sulawesi, Indonesia. Besides Rhantus suturalis (W.S. Macleay, 1825) it is the second species of the genus recorded from Sulawesi. Altogether nine species of the genus are now known from Indonesia. The median lobe of the new species is very similar to Rhantus interclusus (Walker, 1858), endemic to the highlands of Sri Lanka, but the species can be easily distinguished by body size, coloration of the pronotum and the slightly different curvature of median lobe.

Abstract: Darwin wasps represent the most species-rich family of parasitoid wasps but remain strongly understudied, with many species yet to be formally described. This is especially the case for the subfamily Campopleginae, a group of koinobiont endoparasitoids of various holometabolan insect orders. We studied most Campopleginae specimens housed at three major Swiss natural history collections, including 1,046 specimens of Hyposoter. We identified 53 of the 71 Western Palaearctic Hyposoter species in Switzerland, including 46 first records, one of which we describe as a new species. Using abundance-based coverage estimators, we estimate 54–61 Hyposoter species in the country. We show that the genus is more species-rich at low altitude and that only three species can be considered as high-altitude specialists, as many show broad altitudinal ranges. We describe Hyposoter beaumonti sp. nov. from Western Switzerland and establish three new synonyms: Hyposoter monensis Galsworthy & Shaw, 2023 of Phobocampe nigra Sedivy, 2004 (syn. nov.), the former becoming the valid name because the latter becomes a secondary homonym of Hyposoter niger (Brullé, 1846), Hyposoter castaneus Galsworthy & Shaw, 2023 of Lemophagus curtus Townes, 1965 (syn. nov.), and Hyposoter caedator corsicator Aubert, 1960 of Hyposoter caedator (Gravenhorst, 1829) (syn. nov.). Our findings underscore the critical role of diversified sampling strategies—including along altitudinal gradients—and up-to-date taxonomic revisions. They also highlight the importance of digitizing and publishing collection data after accurate identification, thereby enhancing the accessibility of ecological and biological information stored in natural history collections for future research.

Abstract: The temperate Palaearctic genus Camarotoscena (Liviidae, Liviinae) is revised to contain 10 species confirming previous morphology-based species concepts. The results of the molecular analyses were only partly conclusive, as the barcoding genes used (COI and cytb) did not provide sufficient resolution to recognise all species. Both markers showed no differences between the taxa in two species pairs: C. fulgidipennis – C. hoberlandti and C. speciosa – C. subrubescens, while cytb also failed to distinguish C. trjapitzini from C. fulgidipennis – C. hoberlandti. Morphological characters of fifth instar immatures, available for half of the species, supported the species diagnosed by adult characters. Five new synonymies are proposed: Camarotoscena subrubescens (Flor 1861b) = C. ujenci Klimaszewski (1982), syn. nov.; Camarotoscena bianchii Loginova (1975b) = C. pamirica Baeva (1983a), syn. nov., = C. wulingshanica Li (2011), syn. nov., = C. wutaishanica Li (2011), syn. nov., = C. xinjiangica Li (2011), syn. nov. The previously unknown female of C. lauta is diagnosed and its terminalia are illustrated. Illustrated identification keys are provided for the adults and, where known, for the fifth instar immatures. New country records are provided for C. fulgidipennis (India: Ladakh), C. hoberlandti (India: Ladakh), C. lauta (Turkey: Ankara) and C. trjapitzini (Iran: Tehran, Yazd; Spain). The record of C. hoberlandti from Jordan is a misidentification of C. trjapitzini. All species are, as far as known, narrowly oligophagous on Populus spp. (Salicaceae), and the immatures induce leaf roll galls.

Abstract: Northeastern Algeria has recently emerged as a hotspot of freshwater biodiversity and a refugium for both mountainous cold stenothermic and Afrotropical relict species. Intensive surveys of mayflies uncovered striking cryptic diversity within the genus Habrophlebia Eaton, 1881 (Ephemeroptera, Leptophlebiidae). By integrating molecular and morphological evidence, we describe five new species (H. callensis sp. nov., H. ghora sp. nov., H. seybouse sp. nov., H. annaba sp. nov., and H. edough sp. nov.). Our findings increase the number of recognised Habrophlebia species in the Maghreb from nine to fourteen, all of which are endemic to the region. The results further suggest that northeastern Algeria constitutes a major diversification centre for Habrophlebia within the Maghreb and, more broadly, across the Mediterranean basin. Furthermore, distributional patterns support an east–west divide within the Maghreb, most likely shaped by distinct Quaternary glacial refugia. Finally, we provide an updated identification key to the nymphs of Habrophlebia species in the western Palaearctic.

Abstract: For the first time an extensive study on mosquitoes (Diptera: Culicidae) was carried out in and around the Grande Cariçaie nature reserves, a wetland area along Lake Neuchâtel in Western Switzerland. This study contributes to improve knowledge on Swiss regional mosquito distribution and diversity, which is important both from a conservation perspective and for a possible assessment of future risks for human and animal health. Fifteen sites were sampled monthly between April and September 2019 by setting CDC miniature light traps and by investigating larval habitats. The sampling sites were located either in a natural, peri-urban or urban environment. Overall, a total of 3,674 mosquito specimens were identified. A high species diversity with 17 different species and a species composition typical for a wetland area with Ae. annulipes-cantans, Ae. vexans, Ae. sticticus, Ae. cinereus-geminus and Ae. rusticus as dominant species, was found. A strong overlap between the three categories of environments regarding species abundance, richness and composition was observed. No invasive mosquito species were recorded in the study area.

Abstract: Entomology-based research projects often involve setting up mass-collecting traps to obtain large-scale data on species or communities. Many of these projects gather not only the target taxa but also a large amount of bycatch, which often remains untouched or is even disposed of once the project has ended. Here, we have examined bycatch that has been collected in a project to promote biodiversity in the forests of the Swiss Pre-Alps. Multiple traps were set up in three forest reserves near deadwood, to monitor xylobiontic beetles as bioindicators between 2015–2018. The resulting bycatch was analysed about eight years later. Specimens were sorted, prepared, and in most cases identified to species level. From the 1,105 analysed bycatch individuals, we focused on 254 species, representing the groups Arachnida (Araneae, Opiliones) and Hymenoptera (Anthophila, Chrysididae, Eumeninae, Ichneumonidae, Pompilidae, and Sphecidae sensu lato). Most samples were recorded in flight interception traps near herb layers and in the tree canopy. Remarkably, we recorded two rare ichneumonid species, Casinaria dubia Tschek, 1871 as a first record for Switzerland and Bioblapsis polita (Vollenhoven, 1878) as a first record for Switzerland since 1958. Furthermore, we found the rare European spider Episinus maculipes Cavanna, 1876, representing a first record for eastern Switzerland. Our study highlights the importance of well curated bycatch samples, even beyond the duration of the project. Future utilization of such samples may provide precious insights into the ecology and distribution of rare taxa.

Abstract: A field survey of hoverflies (Diptera, Syrphidae) was conducted in the municipality of Bergün-Filisur, Canton of Graubünden, in the inner Swiss Alps during 2023 and 2024. This study aimed at: (i) recording a high species richness using a comparatively low sampling effort by experienced syrphidologists along haphazardly selected routes; and (ii) setting a baseline reference for long-term future surveyance. The repeatability of the survey method was tested by comparing the survey results of 2023 with 2024 using rarefaction analyses, and found to be adequate. A total of 173 hoverfly species were recorded in the Bergün sampling area in 2023 and 2024, which is, respectively, 84% and 51% of the known species richness of the municipality of Bergün-Filisur (206 species) and the Canton of Graubünden (341 species). We recorded 3 species new to the Canton of Graubünden (Platycheirus transfugus; Sphaerophoria estebani; Psilota exilistyla), and 14 species that are on the European Red List of Hoverflies, by being endangered (11 species) or vulnerable (3 species). We propose a practical framework for future hoverfly surveyance in Bergün-Filisur, central Alps. The annual survey effort is minimal and can be achieved within the 15–30 June timeframe, requiring either six days of sampling by a single surveyor or three days by two surveyors.

Abstract: Carcina ingridmariae sp. nov. is described from the eastern Mediterranean region (Greece, Croatia, Cyprus, Türkiye). The species differs strikingly from the so far only representative of the genus in the Western Palearctic, C. quercana (Fabricius, 1775), in the DNA barcode and the male and female genitalia, but less conspicuously in habitual characteristics. All diagnostically relevant characters are figured and discussed. The usefulness of comprehensive genetic inventories for recognizing species that have been inadequately considered because they are regarded as unmistakable is discussed.

Abstract: Mayflies (Ephemeroptera) play a crucial role in nutrient cycling and energy transfer between ecotones, making them key indicators of freshwater ecosystem health. As part of a broader study conducted between 2018 and 2022, a survey of rivers and streams across four regions in northeastern Algeria recorded 15 mayfly species, contributing to an updated regional checklist and mapping the distribution of 36 species. Notably, ten species were putatively new to science, with nine awaiting formal description. The survey also documented two rarely recorded burrowing mayfly species and one interstitial species in North Africa, whose mass emergences serve as valuable bioindicators of riverine ecological integrity. Their close association with sediment or hyporheic zones, combined with a high sensitivity to environmental stressors, makes them effective for cost-efficient, rapid assessments of contaminants in fluvial systems. This study advances knowledge of mayfly taxonomy, biogeography, and ecology in the region while providing essential data for freshwater conservation efforts.

Abstract: Dichotrachelus sonjae sp. nov. was discovered in a cold north-exposed scree slope in the Togano ridge area in Piemonte North of Val Grande. It is described and compared with the most similar species. Based on morphology and molecular data presented here, Dichotrachelus lepontinus Osella, 1971, distributed from Piemonte in Italy (Monte Rosa) eastwards to the Misox mountains of Switzerland, is its sister species. Dichotrachelus meregallii Osella, 1971 is another closely related species. Phylogeographic and biogeographical considerations on the development of that particularly lithophilous and high alpine living group of Dichotrachelus are presented.

Abstract: The genus Limbodessus Guignot, 1939 from New Guinea is reviewed. Eight new species are described from the Central Mountain Range of New Guinea, from altitudes of 1,800 up to 3,500 m above sea level: Limbodessus aipo sp. nov., L. aldente sp. nov., L. elit sp. nov., L. habbema sp. nov., L. juliana sp. nov., L. konoensis sp. nov., L. paniai sp. nov., and L. wilhelmina sp. nov. Limbodessus skalei Hendrich, Surbakti & Balke, 2020, described from Waigeo Island, is recorded for the first time for New Guinea. All 13 species are illustrated. They can be separated from each other by size, body shape, dorsal coloration, punctation of dorsal surface, but predominantly by the form of the male and female antennomeres and the form of male genitalia. A modified key is presented, and the habitats of most species are illustrated in detail.

Abstract: Same-sex and interspecific sexual behavior have been documented in arthropods, but records remain very scarce. We report a mating attempt of a male Dociostaurus kraussi (Ingenitzky, 1897) (Gomphocerinae) and a male of Oedaleus decorus (Germar, 1825) (Oedipodinae), both grasshoppers (Orthoptera: Acrididae), from the region of the Dzungarian Alatau Mountains in Kazakhstan. A Disc3D scan showed that the cerci of the D. kraussi male clearly connect to the external genitalia of the O. decorus male, but we could not ascertain if the genitalia were inserted or if any sperm was transferred. We consider erroneous recognition the most likely explanation but discuss other potential reasons, concluding that much remains to be learned about the highly complex reproductive behavior of acridid grasshoppers.

Abstract: Anthophora onosmarum is a poorly known bee species described from the Caucasus (Georgia). New fieldwork has revealed that the species is present in Bulgaria and Greece, and is also widespread across Turkey, predominantly on the Anatolian plateau. New behavioural data shows that A. onosmarum is likely narrowly oligolectic on the plant genus Onosma (Boraginaceae), and is capable of buzzing flowers to release pollen. This finding illustrates the growing trend of overlooked bee species with more Caucasian, Anatolian, or even Middle Eastern distributions occurring in under-surveyed mountainous parts of the Southern Balkans.

Abstract: The leafcutter bee Megachile genalis Morawitz, which nests in thick, erect and usually hollow plant stems, is rare and endangered throughout Europe. In Switzerland, it was recorded only six times in the Grisons between 1932 and 2019. In order to create the necessary basis for the conservation of this rare bee, its distribution, habitat requirements and nesting biology were investigated in the eastern Swiss Alps by systematically searching for its nests, by DNA metabarcoding of the cell-building material, by analysing the pollen contained in abandoned brood cells and larval faeces, and by deducing aspects of the species’ nesting biology from collected old nests. A total of 141 new and 64 old nests were discovered at elevations between 600 m and 1270 m in – with decreasing frequency – the Albula Valley, the Lower Engadine, the Domleschg and the Ruinaulta. The nests were exclusively built in living stems of Peucedanum verticillare (Apiaceae), an up to 2–3 m tall umbellifer that grew on fallow land, road and railway embankments, scree slopes, ruderal areas and forest clearings. The leaf fragments used by the females of M. genalis to construct the brood cells in 20 selected nests were largely from shrubs and trees of the Rosaceae (e.g. Rosa, Rubus, Prunus, Sorbus), rarely also from Corylus (Betulaceae). The pollen in 65 brood cells was exclusively collected on thistles (e.g. Arctium, Carduus, Cirsium) and other Asteraceae. The nests were characterised by a surprisingly high variability in their architecture. They consisted of i) an approximately 6 mm x 9 mm large nest opening gnawed by the female bee at a height of 22–217 cm above ground with her mandibles, which are well adapted to penetrate the hard stem walls due to their enlarged base indicating strong adductor muscles and the short and chisel-like shape; ii) a 5–25 mm thick nest plug built 1.5–45 cm below the nest opening from pith particles, leaf fragments and/or grass fibers; iii) 1–14 brood cells usually arranged in one cigar-like series and lying 11–99 cm below the nest opening; and iv) a facultative 4–40 mm thick basal plug consisting of pith particles and/or leaf fragments. Brood mortality was high: at least 56% of 284 brood cells were unsuccessful due to parasites, mould or unknown reasons, and reproduction completely failed in almost half of 46 nests. The most harmful brood parasite was Melittobia acasta Walker (Hymenoptera, Eulophidae), which infested 19% of the brood cells and 28% of the nests. Measures to conserve the population of M. genalis in the eastern Swiss Alps should focus on the conservation and propagation of suitable habitats for P. verticillare in close vicinity to Asteraceae-rich areas and on the promotion of thistles.

Abstract: A new species of concealer moths (Oecophoridae), Denisia cryptica sp. nov., is described from specimens collected in the south-western Alps (Italy, France). It differs from similar congeneric taxa of the Denisia stipella species-group by a combined pattern of colour and markings of the forewing upperside, the colour of the head, particularly the yellow second segment of the labial palpi, and by highly divergent DNA barcode (cytochrome c-oxidase subunit 1) sequences. Male and female genitalia are like several other species, with only subtle diagnostic characters. Adult and partially genitalia of D. cryptica sp. nov. and the closest European species are shown for comparison. Finally, a complete checklist of European species of Denisia is added.

Abstract: An updated checklist of the Swiss species of Hydradephaga (Dytiscidae, Gyrinidae, Haliplidae, Hygrobiidae, Noteridae) is presented and briefly discussed. A total of 139 species is retained as part of the Swiss fauna, while 53 species, which have been recorded in Switzerland in the past, are excluded from this list, either due to insufficient documentation or because their records were based on misidentified material. In contrast to previous works, the present study also provides, for the first time, distribution maps through an online map server for all Hydradephaga species in Switzerland, based on over 43,000 occurrences obtained from specimens held in museums and private collections, as well as literature data. The occurrences of the rarest species of Switzerland, as well as data on species erroneously cited in Switzerland, are presented and discussed.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Abstract: We use molecular phylogenomic as well as morphological data to provide a taxonomic update on New Guinea endemic Philaccolilus diving beetles. 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Abstract: Cooka incisa (Cook, 1956) is recorded from several wooded localities in southern Switzerland (canton of Ticino). This is the first European record of this species, as well as the first record of the otherwise Nearctic genus Cooka Amorim, 2007 in the Palaearctic region as a whole. The possibility of an accidental introduction of C. incisa in Europe is discussed.
