Euanoma Reitter, 1889 is the most species-rich genus within the small elateroid family Omalisidae. Here, we redescribe the genus and describe and figure Euanoma plonskii sp. nov., E. trabzonensis sp. nov., E. vavrai sp. nov., and E. wittmeri sp. nov. from Turkey. Euanoma obscura (Pic, 1901) is reported for the first time from Greece (Lesbos, Samos). Euanoma graeca (Pic, 1901b) is transferred to Cimbrion Kazantsev, 2010 as C. graecum (Pic, 1901b) and compared with C. nigricorne (Reitter, 1881). Sixteen described species of Euanoma are known from the Ionian Islands, the Peloponnese, the Aegean Islands, Asia Minor, and the Caucasus. For each species we provide synonyms, information on type material, type locality, diagnosis, distribution, and bibliography. The species distribution map as well as an identification key for the males of all Euanoma species is provided.
