Tachyporinae Revisited: Phylogeny, Evolution, and Higher Classification Based on Morphology, with Recognition of a New Rove Beetle Subfamily (Coleoptera: Staphylinidae)

Abstract

Tachyporinae are one of the most phylogenetically problematic subfamilies in the mega-diverse rove beetle family Staphylinidae. Despite its high diversity and abundance in forest micro-environments, with over 1600 species worldwide, several previous studies had refuted the monophyly of this subfamily and its largest tribe, Tachyporini. Based on the results of morphology-based phylogenetic analyses and direct examination of specimens encompassing two extinct and all forty extant genera, a new suprageneric classification of Tachyporinae is proposed here, with the removal of the tribe Mycetoporini into a newly recognized subfamily Mycetoporinae stat. nov. Four tribes with two subtribes are arranged within Tachyporinae sensu nov.: Tachyporini sensu nov. (Tachyporina stat. nov., sensu nov. and Euconosomatina stat. rev., sensu nov.), Vatesini sensu nov., Deropini, and Tachinusini stat. rev., sensu nov. (= Megarthropsini syn. nov.). Urolitus syn. nov. is placed as a junior synonym of Sepedophilus, and Palporus stat. nov. is raised to a distinct genus from a subgenus of Tachyporus sensu. nov., and †Mesotachyporus syn. nov. is treated as synonym of the latter. Mycetoporine Bobitobus stat. rev. is resurrected from synonymy with Lordithon sensu nov., and considered as a valid genus. My revised classification provides a novel framework for taxonomic inventories and ecological studies of these groups.

“…Recently, non-destructive techniques have been used more frequently to examine amber inclusions based on 3D reconstructions (Penney 2016). The recent advancement of μ-CT and propagation phase-contrast X-ray synchrotron imaging has opened new windows for achieving high-quality reconstructions and individual X-ray sliced images for amber beetles (e.g., Chatzimanolis et al 2013;Zanetti et al 2016;Jałoszyn ´ski et al 2018Jałoszyn ´ski et al , 2020Bukejs et al 2020a, b;Shavrin & Kairišs 2020, 2021Alekseev et al 2021;Perreau et al 2021;Schmidt et al 2021). They are useful in excluding extra bubble layers surrounding the surfaces of inclusions (e.g., Yamamoto & Maruyama 2018;Kundrata et al 2020;Kypke & Solodovnikov 2020;Shavrin & Yamamoto 2020) and in removing certain extra body parts from reconstructions (e.g., Perreau & Tafforeau 2011;Bukejs et al 2020a, b).…”

“…Of the 33 recognised extant subfamilies of rove beetles (Yamamoto 2021), Phloeocharinae comprises seven genera with about 60 species worldwide, representing only a tiny fraction of the overwhelming mega-diversity of Staphylinidae. Roughly two-thirds of the known species belong to the genus Phloeocharis van Mannerheim, 1830, and the remaining genera are each monogeneric or containing, at most, only several species (Newton et al 2000;Chatzimanolis et al 2013;Assing 2015).…”
