Abstract
The genus Pseudoligota Cameron, 1920 is discovered in Japan for the first time, resulting in two taxonomic changes: a new combination P. antennata (Bernhauer, 1907), comb. nov., and a new species P. nozakii Hashizume, Yamamoto & Maruyama, sp. nov. from Okinawa Prefecture, southwestern Japan. The former species has long been placed in the genus Oligota Mannerheim, 1830. This is the fourth genus in the subtribe Gyrophaenina known from Japan. The species P. affinis Cameron, 1939 from India and Peninsular Malaysia is placed as a junior synonym of P. antennata.
