Four new synonyms in the stag-beetle genus Aegus MacLeay from Chinese fauna are proposed and discussed based on their type specimens: A. pichoni Didier 1931, syn. nov. = A. laevicollis Saunders 1854; A. beauchenei Boileau 1902, syn. nov. and A. caprinus Didier, 1928, syn. nov. =A. taurus Boileau, 1899; A. dispar Dider 1931, syn. nov. =A. kuangtungensis Nagel, 1925. A species checklist with fifteen species of this genus from China is given, including two new record species, A. labilis Westwood, 1864 from Xizang and A. coomani Didier, 1926 from Guangxi.
