Dorcus jinghongi sp. nov. is described from Guizhou and Guangxi. Two new localities are recorded for Dorcus fujiii Nagai & Maeda, 2010. Dorcus tenuecostatus Fairmaire, 1888 is considered an undefinable taxon, with the following consequent taxonomic changes made: Dorcus tenuihirsutus Kim & Kim, 2010 stat. rev. and Falcicornis pieli (Didier & Séguy, 1953) stat. rev. are revised as bona species. Falcicornis ruiliensis Huang & Chen, 2017 syn. nov. is treated as a junior synonym of Falcicornis virginiae (Bomans, 1991). Prosopocoilus astacoides reni Huang & Chen, 2011 stat. nov. is considered a subspecies of Prosopocoilus astacoides (Hope, 1840) on evidence of cross breeding. Prismognathus katsurai Ikeda, 1997 is recorded as new to Chinese fauna. Aegus imitator Nagel, 1941 is revised, with neotype designated. A. eschscholtzii (Hope, 1845) is excluded from Chinese fauna.
