Revision of emEccoptolonthus/em Bernhauer (Coleoptera: Staphylininae: Philonthina) with descriptions of four new species from China.

This study revises the taxonomy of the genus Eccoptolonthus Bernhauer, 1912 and reports 14 species in the Chinese fauna. A catalogue of the remaining 15 Eccoptolonthus species from the Oriental and Afrotropical regions is also provided. Four new species are described from China: Eccoptolonthus conaensis Fei Zhou, sp. nov. from Tibet, Eccoptolonthus fuyuensis Fei Zhou, sp. nov. from Zhejiang, Eccoptolonthus dafoensis Fei Zhou, sp. nov. from Guizhou, and Eccoptolonthus xiaolongmenensis Fei Zhou, sp. nov. from Beijing. Eccoptolonthus (Eumorimotous) laevigatus laevigatus (Fauvel, 1895) is reported for the first time from Yunnan in China and Vietnam. A preliminary key to the Chinese species of Eccoptolonthus is also included in the paper. Color images and line drawings are provided to show diagnostic characters.
