Two new genera of Lathrobiina from the East Palaearctic region (Coleoptera: Staphylinidae: Paederinae).

Two genera of Lathrobiina are described, illustrated, and distinguished from Lathrobium Gravenhorst, 1802 and allied genera: Elytrobium gen. n. (type species: Lathrobium monilicorne Sharp, 1889) and Sinlathrobium gen. n. (type species: Lathrobium lobrathiforme Assing, 2012). Elytrobium is distributed in the southeast of the East Palaearctic region and includes six species: E. monilicorne (Sharp, 1889), comb. n. (Japan); E. gongganum sp. n. (China: Gongga Shan); E. qinlinganum sp. n. (China: Qinling Shan); E. seminitidum sp. n. (China: Shaanxi); E. scindens sp. n. (China: Daba Shan); E. alesianum sp. n. (Taiwan). Sinlathrobium comprises four species from China: S. lobrathiforme (Assing, 2012), comb. n. (Yunnan); S. lobrathioides (Assing, 2012), comb. n. (transferred from Lathrobium) (Chongqing); S. densepunctatum sp. n. (Sichuan); S. iniquum sp. n. (Yunnan). Keys to the species of both genera are provided, and their distributions are mapped. Although all the species of both genera appear to be fully winged, four of the six Elytrobium and all the Sinlathrobium species have been recorded from only a single locality each. Three Elytrobium and three Sinlathrobium species are currently represented only by their respective holotypes.Stichwörter Coleoptera, Staphylinidae, Paederinae, Lathrobiina, Elytrobium, Sinlathrobium, Lathrobium, Lobrathium, Tetartopeus, East Palaearctic region, China, Taiwan, Japan, taxonomy, new genera, new species, new combinations, key to species, distribution mapsNomenklatorische Handlungenalesianum Assing, 2013 (Elytrobium), spec. nov.gongganum Assing, 2013 (Elytrobium), spec. nov.monilicorne (Sharp, 1889) (Elytrobium), LT; comb. nov. hitherto Lathrobium monilicorne Sharp, 1889quinlinganum Assing, 2013 (Elytrobium), spec. nov.scindens Assing, 2013 (Elytrobium), spec. nov.seminitidum Assing, 2013 (Elytrobium), spec. nov.Elytrobium Assing, 2013 (Lathrobiina), gen. nov.Sinlathrobium Assing, 2013 (Lathrobiina), gen. noc.densepunctatum Assing, 2013 (Sinlathrobium), spec. nov.iniquum Assing, 2013 (Sinlathrobium), spec. nov.lobrathiforme (Assing, 2012) (Sinlathrobium), comb. nov. hirtherto Lathrobium lobrathiforme Assing, 2012lobrathioides (Assing, 2012) (Sinlathrobium), comb. nov. hitherto Lathrobium lobrathioides Assing, 2012Zwei Gattungen aus der Subtribus Lathrobiina werden beschrieben, abgebildet und von Lathrobium Gravenhorst, 1802 und verwandten Gattungen unterschieden: Elytrobium gen. n. (Typusart: Lathrobium monilicorne Sharp, 1889) und Sinlathrobium gen. n. (Typusart: Lathrobium lobrathiforme Assing, 2012). Elytrobium ist mit sechs Arten in der südöstlichen Ostpaläarktis verbreitet: E. monilicorne (Sharp, 1889), comb. n. (Japan); E. gongganum sp. n. (China: Gongga Shan); E. qinlinganum sp. n. (China: Qinling Shan); E. seminitidum sp. n. (China: Shaanxi); E. scindens sp. n. (China: Daba Shan); E. alesianum sp. n. (Taiwan). Die Verbreitung der vier Sinlathrobium-Arten beschränkt sich auf China: S. lobrathiforme (Assing, 2012), comb. n. (Yunnan); S. lobrathioides (Assing, 2012), comb. n. (vorher Lathrobium) (Chongqing); S. densepunctatum sp. n. (Sichuan); S. iniquum sp. n. (Yunnan). Für beide Gattungen werden Bestimmungstabellen erstellt; ihre Verbreitung wird anhand von Karten illustriert. Obwohl wahrscheinlich alle Arten beider Gattungen voll ausgebildete Flügel besitzen, sind vier der sechs Elytrobium- und alle Sinlathrobium-Arten lediglich von jeweils einem Fundort bekannt. Drei Elytrobium- und drei Sinlathrobium-Arten sind derzeit lediglich durch die jeweiligen Holotypen vertreten.Keywords Coleoptera, Staphylinidae, Paederinae, Lathrobiina, Elytrobium, Sinlathrobium, Lathrobium, Lobrathium, Tetartopeus, East Palaearctic region, China, Taiwan, Japan, taxonomy, new genera, new species, new combinations, key to species, distribution mapsNomenclatural Actsalesianum Assing, 2013 (Elytrobium), spec. nov.gongganum Assing, 2013 (Elytrobium), spec. nov.monilicorne (Sharp, 1889) (Elytrobium), LT; comb. nov. hitherto Lathrobium monilicorne Sharp, 1889quinlinganum Assing, 2013 (Elytrobium), spec. nov.scindens Assing, 2013 (Elytrobium), spec. nov.seminitidum Assing, 2013 (Elytrobium), spec. nov.Elytrobium Assing, 2013 (Lathrobiina), gen. nov.Sinlathrobium Assing, 2013 (Lathrobiina), gen. noc.densepunctatum Assing, 2013 (Sinlathrobium), spec. nov.iniquum Assing, 2013 (Sinlathrobium), spec. nov.lobrathiforme (Assing, 2012) (Sinlathrobium), comb. nov. hirtherto Lathrobium lobrathiforme Assing, 2012lobrathioides (Assing, 2012) (Sinlathrobium), comb. nov. hitherto Lathrobium lobrathioides Assing, 201
