DOI: 10.3897/alpento.7.109855

Authors: Kôji Sasakawa

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

NextRAD phylogenomics, sanger sequencing and morphological data to establish three new species of New Guinea stream beetles https://alpineentomology.pensoft.net/article/86665/ Alpine Entomology 6: 51-64

DOI: 10.3897/alpento.6.86665

Authors: Michael Balke, Rawati Panjaitan, Suriani Surbakti, Helena Shaverdo, Lars Hendrich, Matthew H. Van Dam, Athena Lam

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.

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

DOI: 10.3897/alpento.6.79598

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

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

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

DOI: 10.3897/alpento.4.55139

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

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

Nebria (Pseudonebriola) tsambagarav sp. nov., a new alpine species from the Mongolian Altai (Coleoptera, Carabidae) https://alpineentomology.pensoft.net/article/50408/ Alpine Entomology 4: 29-38

DOI: 10.3897/alpento.4.50408

Authors: Charles Huber, Peer Hajo Schnitter

Abstract: Nebria (Pseudonebriola) tsambagarav sp. nov. is described from an alpine altitude in the Mongolian Altai. The new species is separated from other two Pseudonebriola species from the Mongolian Altai Mountain range, N. kerzhneri and N. medvedevi, by morphometric and morphological analyses. The new species and its habitat are illustrated, the subgeneric key is amended, and a distribution map is given.

A new species of Rhantus diving beetles from the wetlands of the City of Bogota and surroundings (Coleoptera, Dytiscidae, Colymbetinae) https://alpineentomology.pensoft.net/article/37308/ Alpine Entomology 3: 169-174

DOI: 10.3897/alpento.3.37308

Authors: Michael Balke, Rodulfo Ospina-Torres, Yoandri S. Megna, Marco Laython, Lars Hendrich

Abstract: The Colombian species of the genus Rhantus are reviewed. Rhantus bogotensis sp. nov. is described and illustrated, based on specimens collected in the Altiplano of the Bogota region. It is compared with the similar species Rhantus franzi, R. vicinus, and R. crypticus. The Ecuadorian species Rhantus crypticus was found for the first time in the highlands of Nariño department. This is a new record for Colombia. Five species of Rhantus are presently known from Colombia.

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

DOI: 10.3897/alpento.3.30417

Authors: Aline Knoblauch, Antoine Gander

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

Amended description and new combination for Entomophthora nebriae Raunkiaer, (1893), a little known entomopathogenic fungus attacking the ground beetle Nebria brevicollis (Fabricius, 1792) https://alpineentomology.pensoft.net/article/22136/ Alpine Entomology 2: 1-5

DOI: 10.3897/alpento.2.22136

Authors: Siegfried Keller, Thorben Hülsewig

Abstract: A fungus attacking the ground beetle Nebria brevicollis (Fabricius, 1792) (Coleoptera, Carabidae) was collected in north-western Germany. The fungus was identical to Entomophthora nebriae Raunkiaer, 1893 (Entomophthoromycotina, Entomophthoraceae), described in 1893 from Denmark and so far only known from the type collection. We provide an amended description of E. nebriae based on the new collection and transfer the species to the genus Erynia as Erynia nebriae comb. n.
