Krivosheeva, V., A. Solodovnikov, A. Shulepov, D. Semerikova, A. Ivanova, and M. Salnitska. 2023. Assessment of the DNA barcode libraries for the study of the poorly-known rove beetle (Staphylinidae) fauna of West Siberia. Biodiversity Data Journal 11. https://doi.org/10.3897/bdj.11.e115477

Staphylinidae, or rove beetles, are one of the mega-diverse and abundant families of the ground-living terrestrial arthropods that is taxonomically poorly known even in the regions adjacent to Europe where the fauna has been investigated for the longest time. Since DNA barcoding is a tool to accelerate biodiversity research, here we explored if the currently-available COI barcode libraries are representative enough for the study of rove beetles of West Siberia. This is a vast region adjacent to Europe with poorly-known fauna of rove beetles and from where not a single DNA barcode has hitherto been produced for Staphylinidae. First, we investigated the faunal similarity between the rove beetle faunas of the climatically compatible West Siberia in Asia, Fennoscandia in Europe and Canada and Alaska in North America. Second, we investigated barcodes available for Staphylinidae from the latter two regions in BOLD and GenBank, the world's largest DNA barcode libraries. We conclude that the rather different rove beetle faunas of Fennoscandia, on the one hand and Canada and Alaska on the other hand, are well covered in both barcode libraries that complement each other. We also find that even without any barcodes originating from specimens collected in West Siberia, this coverage is helpful for the study of rove beetles there due to the significant number of widespread species shared between West Siberia and Fennoscandia and due to the even larger number of shared genera amongst all three investigated regions. For the first time, we compiled a literature-based checklist for 726 species of the West Siberian Staphylinidae supplemented by their occurrence dataset submitted to GBIF. Our script written for mining unique (i.e. not redundant) barcodes for a given geographic area across global libraries is made available here and can be adopted for any other regions.

The genus Brachysomus Schoenherr, 1823 is reviewed. A comparative morphological study of adults from 56 Brachysomus species is provided. Redescriptions, diagnoses and identification keys are given. Descriptions of two new species are provided: B. (s. str.) podlussanyi sp. n. from Greece and B. (s. str.) pseudosetiger sp. n. from Bulgaria, which appear to be closely related to B. (s. str.) mihoki Penecke, 1914. Females of B. (s. str.) longipterus Białooki, 2007 are described. The poorly known B. (Hippomias) moczarskii Penecke, 1924 is restored from synonymy with B. (H.) oertzeni Faust, 1889. New synonyms: B. (s. str.) echinatus (Bonsdorff, 1785) = B. (s. str.) hirsutus Iablokoff-Khnzorian, 1958 syn. n. New combinations: Brachysomus (s. str.) lituratus (Reitter, 1884) comb. n. from Foucartia Jacquelin du Val, 1854; Eurosphalmus tenuicollis (Yunakov, 2006) comb. n. from Brachysomus, Eurosphalmus cribrarius (Białooki, 2007) comb. n. from Brachysomus, Nanomias skodai (Białooki, 2007) comb. n. from Brachysomus, and Chiloneus bonnairei (Hoffmann, 1942) comb. n. from Brachysomus. Lectotypes are designated for: Strophosomus hirtus Boheman, 1845; Brachysomus ornatus Stierlin, 1892; B. bensae Stierlin, 1893; Platytarsus fasciatus Stierlin, 1899; and P. setiger Gyllenhal, 1840. For each species, all known localities are presented on a distribution map. Ecological preferences of Brachysomus species are specified. First records of Brachysomus (s. str.) fremuthi Košťál, 1991 from Romania, B. (Hippomias) carpathicus Košťál, 1992 from Serbia, and B. (H.) ponticus Apfelbeck, 1898 from Greece are given.

Brygadyrenko, V., T. Avtaeva, and A. Matsyura. 2021. Effect of global climate change on the distribution of Anchomenus dorsalis (Coleoptera, Carabidae) in Europe. Acta Biologica Sibirica 7: 237–260. https://doi.org/10.3897/abs.7.e72409

Shifts in the bioclimatic range of Anchomenus dorsalis – specialized entomophage – were modeled in the MaxEntsoftware package and are presented on habitat maps. For the prediction, we used two climatic scenarios – mild (RCP2.6) and extreme (RCP8.5). Under the considered scenarios, …

Insects are the focus of many recent studies suggesting population declines, but even invaluable pollination service providers such as bees lack a modern distributional synthesis. Here, we combine a uniquely comprehensive checklist of bee species distributions and >5,800,000 public bee occurrence re…

Palaeogeography, Palaeoclimatology, Palaeoecology 514: 672–676. https://doi.org/10.1016/j.palaeo.2018.11.025

Well-preserved beetle elytra from the fossil and subfossil record are used by palaeoclimatologists to estimate past temperatures. Beetle-derived estimates of temperature across the Pliocene Arctic are consistently lower than those derived from other palaeoclimate proxies. Here we test if that patter…
