Abstract
Four new staphylinid species from China are described, based on material collected from Tangli Mountain, Yunnan: Euconnus (s. str.) vertexalis Li & Yin, sp. nov. and Syndicus (Semisyndicus) wangjisheni Li & Yin, sp. nov. of the subfamily Scydmaeninae, and Tmesiphorus tanglimontis Li & Yin, sp. nov. and Tribasodites tubericeps Li & Yin, sp. nov. of the subfamily Pselaphinae. Illustrations of the habitus and major diagnostic characters of each new species are provided.
