Three new species of the subgenus Latotachinus Ullrich, 1975 (Coleoptera: Staphylinidae: Tachyporinae) from China

Abstract

Summary Three new species belonging to the subgenus Latotachinus Ullrich, 1975 of the genus Tachinus Gravenhorst, 1802 are described from China: T. microsculpturatus n. sp. and T. murzini n. sp. from the alpine areas of Sichuan, and T. nanlingensis n. sp. from Nanling Nature Reserve, Guangdong. The former two species share the greatly reduced elytra, lack of wing-folding patches of the abdomen, and most remarkably, the presence of microsculpture on the head and pronotum. Tachinus nanlingensis n. sp. is morphologically similar to T. (Latotachinus) sinensis Li & Zhao, 2002 distributed in Zhejiang, eastern China by the exceptionally dense and long setae of the abdomen, and is compared with and separated from that species. Thus, the number of species of Latochinus is increased from four to seven. A distributional map of and a key to all known species is provided.
