The Korean species of the genera Cremastus Gravenhorst, 1829 and Pristomerus Curtis, 1836 (Hymenoptera: Ichneumonidae) are studied. Here we report three species, Cremastus crassitibialis Uchida, 1940, Pristomerus rufiabdominalis Uchida, 1928 and P. scutellaris Uchida, 1932, new to South Korea. Among them genus Cremastus is recorded for the first time from South Korea. The number of Korean Cremastinae is now 11 species in four genera including the three newly recorded species. A key to the genera of Korean Cremastinae, diagnosis of newly recorded species and photographs of redescriptions characters are provided.
