The family Pteromalidae are one of the numerous and economically important groups of parasitoids, but our knowledge of this group in South Korea is limited. Up to date, only 39 species of 27 genera belonging to five subfamilies have been recorded from south Korea. This study is based on the material from the Applied Entomology Division, Department of Agricultural Biology, National Academy of Agricultural Science (NAAS) and Yeungnam University, Gyeongsan, South Korea (YNU). As a result of this study, four species (Diglochis sylvicola (Walker), Lariophagus obtusus Kamijo, Mokrzeckia lazoensis Tselikh, Paracarotomus cephalotes Ashmead,) in Pteromalinae are recorded for the first time in South Korea. Among them two genera (Diglochis Förster, Paracarotomus Ashmead,) recorded for the first time in South Korea. Therefore, 43 species of 29 genera in Pteromalidae are recorded from South Korea.
