The family Monotomidae Laporte includes about 240 species placed in 33 genera worldwide and five species in three genera have been recorded to date in the Korean Peninsula. Mimemodes Reitter contains 15 species occurring worldwide including nine Palaearctic species, of which five are recorded in Japan. In the Korean Peninsula, the genus and a single species, Mimemodes emmerichi Mader, were first recorded by Kang et al. In the present study, we report an additional Korean species of the genus, namely Mimemodes cribratus (Reitter). We provide a redescription, images of habitus and diagnostic characters of the species along with a key to Korean species of Monotomidae.
