Abstract: The genus Eubadura Sawada, 1990 stat. nov. (Athetini: Athetina) which has formerly been regarded as a subgenus of the genus Atheta Thomson, 1858, from Japan is revised. The genus Osakatheta Maruyama, Klimaszewski & Gusarov, 2008 is synonymized with Eubadura. Four species are recognized in the genus: Eubadura akiensis (Sawada, 1990), comb. nov. (Japan: Hokkaidô, Honshû, Shikoku, Kyûshû), E. yasukoae (Maruyama, Klimaszewski & Gusarov, 2008), comb. nov. (Japan: Honshû; Korea), E. onoi sp. nov., (Japan: Honshû) and E. hokkaidensis sp. nov. (Japan: Hokkaidô). Key to the species is given, and a systematic position of Eubadura is discussed.
