Psilomma Förster, a small and rare genus within the tribe Pantolytini (Diapriidae: Belytinae), consists of three species widely distributed in Europe: P. dubium Kieffer, 1908; P. fuscicornis Kieffer, 1908; P. fusciscapis Förster, 1861 (Macek 1990). This genus is easily distinguished from other Pantolytini genera by the sickle form of mandibles. Up to date, Psilomma has not yet been recorded out of Europe. As a result of the present study, the genus Psilomma is reported from the South Korea for the first time based on a species of P. dubium. Also, the known range of Psilomma is extended from Europe (Western Palaearctic) to South Korea (Eastern Palaearctic). A detailed redescription, photographs of this species are given.
