Alaolacon Cand???¨ze, 1865 is found to be a senior synonym of Eumoeus Cand???¨ze, 1874, Luzonicus Fleutiaux, 1916 and Tharopsides Fleutiaux, 1918. Alaolacon is represented by Alaolaconbakeri (Fleutiaux, 1916), comb. n., Alaolaconcandezei Fleutiaux, 1928, Alaolaconcyanipennis Cand???¨ze, 1865, Alaolaconfujiokaisp. n., Alaolacongriseus Cand???¨ze, 1874, Alaolaconmegalopussp. n., Alaolaconmurrayi (Cand???¨ze, 1874), comb. n., and Alaolaconphilippinensisnom. n. This genus is redescribed based on the descriptions of three species, Alaolaconcandezei, Alaolaconfujiokai, and Alaolaconmegalopus as well as the examination of the holotypes of Alaolaconcyanipennis and Alaolaconmurrayi comb. n. Males of the genus Alaolacon exhibit 12-segmented and biflabellate antennae, and the females exhibit 11-segmented and subpectinate antennae. A key to species is provided.
