Asaphinae Ashmead, 1904 are the smallest subfamily in Pteromalidae and currently include 27 extant species of 6 genera. Up to date, only 2 species, Asaphes suspensus (Nees) and A. vulgaris Walker, have been recorded from South Korea. Among them A. vulgaris Walker is suspected of misidentified due to several reasons. Hyperimerus Girault, a small genus of the subfamily Asaphinae, consists of two world-wide species. It is close to Asaphes Walker but is separated by the following characteristics: antenna with one anelliform segment; scutellar frenum not distinct; petiole transverse. In this study, we report genus Hyperimerus based on Hyperimerus pusillus (Walker) for the first time from South Korea and Eastern Palearctic region. Also, a key to the genera of Asaphinae from South Korea, diagnosis, photographs of each species and taxonomic note of A. vulgaris Walker are provided.

Chalcididae Latreille, 1817 currently include 1,464 extant species in 87 genera in the world. This family is probably easy to define taxonomically. Body robust with coarse puncture, prepectus extremely narrow, hind femur typically swollen and on inner margin with one or more teeth. Members of this family are primary endoparasitoids on pupa of Diptera and Lepidoptera. Up to date, only 12 species of 6 genera belonging to three subfamilies have been recorded from South Korea. As a result of this study, six species (Chalcis sp. 1, Conura sp. 1, Haltichella cf. nipponensis Habu, Hockeria cf. bifasciata Walker, Proconura sp. 1 and Steninvreia cf. petiolata Bouček) in Chalcididae are recorded for the first time in South Korea. Among them four genera (Haltichella Spinola, Hockeria Walker, Proconura Dodd and Steninvreia Bouček) are recorded for the first time in South Korea. Therefore, 18 species of 10 genera in Chalcididae are recorded from South Korea.

Pteromalinae Dalman, 1820 are the largest subfamily in Pteromalidae and currently include 2,073 extant species of 314 genera. This group is probably difficult to define taxonomically. Members of this subfamily are endoparasitoids of Lepidoptera, Diptera and Coleoptera larvae and pupae. Up to date, only 46 species of 30 genera belonging to five subfamilies have been recorded from South Korea. As a result of this study, we reported 25 unrecorded species of 13 genera for the first time from South Korea. Therefore, 71 species of 43 genera in Pteromalinae are recorded from South Korea.

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.
