Dichodactylus gen. nov. (type species Coelotes tarumii Arita, 1976) is described from western Japan. Three species are recognized: Dichodactylus shinshuensis sp. nov., D. tarumii (Arita, 1976) comb. nov. (transferred from Coelotes Blackwall, 1841), and D. satoi (Nishikawa, 2003) comb. nov. (transferred from Orumcekia Koçak and Kemal, 2008). Dichodactylus is compared with Orumcekia, especially morphological similarities in the male palps. Diagnostic and descriptive characteristics of the three species are presented including a species distribution map and genitalic illustrations.
