The Pseudolathra species of the East Palaearctic and the Oriental regions (Coleoptera: Staphylinidae: Paederinae).

Abstract

Die verfügbaren Typen und weiteres Material der in der Ostpaläarktis und der Orientalis verbreiteten Arten der Lathrobiinen-Gattung Pseudolathra Casey, 1905 werden revidiert. Die Gattung ist in diesen Regionen mit insgesamt dreizehn Arten vertreten, sechs davon sind neu: P. brevincisa sp. n. (Thailand), P. cordiformis sp. n. (südöstliches Indien), P. himalayana sp. n. (Pakistan, Nordindien, Nepal), P. sagittata sp. n. (Thailand), P. transversicollis sp. n. (Thailand, Nordindien) und P. vellicans sp. n. (Nordindien). Alle behandelten Arten werden beschrieben bzw. redeskribiert; dreizehn Arten werden abgebildet. Pseudolathra pulchella (Kraatz, 1859), bisher Synonym von P. caffra (Boheman, 1848), wird revalidiert. Zwei Namen werden synonymisiert: Pseudolathra pulchella (Kraatz, 1859) = P. caffra javana (Cameron, 1940), syn. n.; P. unicolor (Kraatz, 1859) = P. chujoi (Last, 1966), syn. n. Zwei bislang Lobrathium Mulsant & Rey, 1878 zugeordnete Arten werden in die Gattung Pseudolathra gestellt: P. nigerrima (Cameron, 1924), comb. n., und P. regularis (Sharp, 1889), comb. n. Die ostpaläarktischen und orientalischen Arten einerseits und die westpaläarktischen Arten andererseits bilden separate phylogenetische Linien. Erstere werden vorläufig der Untergattung Allolathra Coiffait, 1972 gestellt, Letztere der Untergattung Pseudolathra zugeordnet. Die in der Ostpaläarktis und der Orientalis vertretenen Arten gehören zu drei Artengruppen. Eine Bestimmungstabelle und ein Katalog werden erstellt. Weitere Nachweise, darunter eine Reihe von Erstnachweisen, werden gemeldet. Die derzeit bekannten Verbreitungsgebiete von zwölf Arten werden anhand von Karten illustriert.StichwörterColeoptera, Staphylinidae, Paederinae, Lathrobiina, Pseudolathra, Palaearctic region, Oriental region, taxonomy, new species, new combinations, new generic assignments, new synonymies, key to species, catalogue, distributions.Nomenklatorische Handlungencafrum [sic] javanum Cameron, 1940 (Lathrobium), syn. nov. of Pseudolathra pulchella (Kraatz, 1859)chujoi Last, 1966 (Lathrobium), syn. nov. of Pseudolathra unicolor (Kraatz, 1859)pulchellum Kraatz, 1859 (Lathrobium), revalidated now: Pseudolathra pulchella (Kraatz, 1859)seriatum Sharp, 1889 (Lathrobium), LT now: Pseudolathra lineata Herman, 2003 (replacent name)unicolor Kraatz, 1859 (Lathrobium), LT now: Pseudolathra unicolor (Kraatz, 1859)brevincisa Assing, 2012 (Pseudolathra), spec. nov.cordiformis Assing, 2012 (Pseudolathra), spec. nov.himalayana Assing, 2012 (Pseudolathra), spec. nov.nigerrima (Cameron, 1924) (Pseudolathra), comb. nov.; LT hitherto Lathrobium nigerrimum Cameron, 1924regularis (Sharp, 1889) (Pseudolathra), comb. nov.; LT hitherto Lathrobium regulare Sharp, 1889sagittata Assing, 2012 (Pseudolathra), spec. nov.transversicollis Assing, 2012 (Pseudolathra), spec. nov.vellicans Assing, 2012 (Pseudolathra), spec. nov.

Generic Revisions of the Scopaeina and the Sphaeronina (Coleoptera: Staphylinidae: Paederinae: Lathrobiini)

“…According to label data published by Assing (2011Assing ( -2015 specimens have been collected primarily in forest litter, deep humus, wet debris near a waterfall at 850 m elevation, near snowfields, and occasionally in open grassland or shrub habitats. Species have been collected at elevations of 270 to 3600 m. The genus appears to be primarily montane.…”

“…The species in those generic groups are now included in species groups of Scopaeus . Hyperscopaeus Coiffait, 1984, new status , is elevated to genus from subgeneric status in Scopaeus . Trisunius Assing, 2011 , new subtribal assignment , is moved from the Medonina to the Scopaeina. Typhloscopaeus Jarrige, 1951, incertae sedis , formerly a subgenus of Scopaeus , is of unknown placement, but the species and generic names are retained in Scopaeus awaiting study of the type. Orus cervicula Casey, 1905, revised combination , is returned to Orus from Scopaeus .…”

New species of the genus Pseudolathra Casey, 1905 (Coleoptera, Staphylinidae, Paederinae) from the Northwestern District of China

“…The genus Pseudolathra Casey, 1905 (Staphylinidae, Paederinae) is a rove beetle genus in the subtribe Lathrobiina with well-developed hind wings, commonly found during light trapping or in debris (Assing 2012). The genus occurs in all zoogeographic regions, though most of the species have been recorded from the East Palaearctic and Oriental regions and many species have restricted distributions (Rougement 2015;Assing 2018Assing , 2019Li et al 2019).…”

“…Based on the most recent knowledge, the genus Pseudolathra was composed of 9 Chinese species by 2019 (Herman 2003;Assing 2012Assing , 2013aAssing , b, 2014Li et al 2013;Peng et al 2014;Li et al 2019), all characterized by the punctures on the forebody, while the middle area of the pronotum is impunctate; the punctures of the elytra are distinctly aligned in rows. Based on material collected recently, two new species from mainland China are described and illustrated here, namely Pseudolathra gansuensis Li & Zhou, sp.…”

“…Based on material collected recently, two new species from mainland China are described and illustrated here, namely Pseudolathra gansuensis Li & Zhou, sp. nov. and P. assingi Li & Zhou, sp. nov., both from Gansu province, China, which can be placed in the P. unicolor species group in the subgenus Allolathra based on the diagnostic characters of that group (Assing 2012). Thus, there are currently 11 species of Pseudolathra known from China.…”
