The family Ichneumonidae belongs to the order Hymenoptera, class Insecta, and includes over 25,000 valid species in 47 subfamilies worldwide. The family occurs worldwide, with more species in cool moist climates than in warm dry ones. Ichneumonids are parasitoids of immature holometabolous insects or Chelicerata (Araneae and Pseudoscorpionida eggs adult Araneae). Symphyta and Lepidoptera, which are agricultural and forestry pests are the most common hosts. Therefore, they are one of most important control agents of the pest populations. This family is known as a monophyletic group with the family Braconidae. The inventory of the Hymenoptera fauna of the Korean peninsula was started from the end of the last century (1887) by O. Radoszkowski. A comprehensive historical review of the faunal study of Hymenoptera has been prepared by Kim (1963) who recorded 921 species, 382 genera in 76 families from the Korean peninsula. Among them, 271 species of Ichneumonidae had been recorded until 1970 from South Korea. Since then, taxonomic study of Ichneumonidae has developed steadily over the past 30 years by several Korean taxonomists. Recently, the frequency of collaboration with foreign specialists has also increased. The current total of South Korean Ichneumonidae is 921 species in 302 genera of 29 subfamilies. It is hoped that more collaborative work in the future will help describe the country’s rich diversity.

The subfamily Pimplinae currently include 1,737 worldwide species in 77 genera. 78 species in 21 genera have been recorded from South Korea. Among them, the genera Exeristes, Gregopimpla and Paraperithous are small groups with 10, 8 and 6 species from worldwide. The existing South Korean Exeristes and Paraperithous include only one species, E. roborator (Fabricius) and P. chui (Uchida). Three species of genus Gregopimpla have been recorded from South Korea, G. himalayensis (Cameron), G. inquisitor (Scopoli) and G. kuwanae (Viereck). In this study, we report three newly recorded species Exeristes longiseta (Ratzeburg), Gregopimpla ussuriensis Kasparyan and Paraperithous gnathaulax (Thomson) from South Korea, including diagnoses, photographs of newly recorded species and keys to the species of South Korean Exeristes, Gregopimpla and Paraperithous.

The subfamily Pimplinae comprising more than 1,700 described species within 77 genera worldwide. Sixty-nine specieswithin 20 genera have been recorded from South Korea. Among them, the genus Endromopoda is a small sized groupin the subfamily Pimplinae with 11 described species from Nearctic, Oriental and Palaearctic regions. This genus is newlyrecorded from South Korea for the first time. Genus Endromopoda can easily be distinguished from other genera of Pimplinaeby the following characters:　Distinctly depressed ovipositor, with perpendicular teeth on apex; elongated propodeum.In this study, we report three unrecorded South Korean species, Endromopoda arundinator (Fabricius,1804), Endromopoda detrita (Holmgren, 1860) and Endromopoda phragmitidis (Perkins, 1957). In addition,diagnoses, photographs of newly recorded species and a key to the species of South Korean Endromopodaare provided.

The subfamily Pimplinae currently include 1,737 worldwide species in 77 genera. 57 species in 18 genera have been recorded from South Korea. Among them, the genus Scambus is a moderate sized group in the subfamily Pimplinae with 152 described species from Nearctic, Neotropical, Oriental and Palaearctic regions. The taxonomic study of the South Korean Scambus was initiated by Uchida (1928), who reported one species, Scambus calobatus (Gravenhorst, 1829). The genus Tromatobia is small group in this subfamily with 33 species from Afrotropical, Austrian, Nearctic, Neotropical, Oriental and Palaearctic regions. This genus was newly recorded from South Korea for the first time. In this study, we report seven unrecorded South Korean species, Scambus nigricans (Thomson, 1877), Scambus vesicarius (Ratzeburg, 1844), Tromatobia flavistellata Uchida & Momoi, 1957, Tromatobia nipponica Uchida, 1928, Tromatobia ornata (Gravenhorst, 1829), Tromatobia ovivora (Boheman, 1821) and Tromatobia variabilis (Holmgren, 1856).

줄뭉툭맵시벌속은 전세계에 145종이 분포하는 비교적 큰 맵시벌 그룹이다. 줄뭉툭맵시벌속은 동구북구 지역에 41종이 기록되어 있으나, 한국에는 8종만이 기록되어 있다. 본 연구에서는 한국산 줄뭉툭맵시벌속 내 13종을 재고찰 하고자 한다. 추가적으로, 미기록 5종을 한국에 처음으로 기록하였으며, 한국산 줄뭉툭맵시벌속의 검색표와 재기재문, 사진을 제시 하였다.
