Abstract

Four species of the genus Exochus belonging to the subfamily Metopiinae, family Ichneumonidae, are reported in South Korea for the first time. The subfamily Metopiinae was recorded by Förster in 1869 based on genus Metopius and more than 870 described species have been reported worldwide. Among the genera of Metopiinae, genus Exochus is the largest, which is cosmopolitan and comprises more than 290 described species worldwide (Choi et al., 2016; Yu et al., 2016). A taxonomic study of South Korean Exochus was initiated by Choi et al. (2014), who reported four species. Until now, 10 species have been described as new species and 25 species were recorded as new records of this genus from South Korea (Choi et al., 2014, 2016). In the present study, the following four species are reported in South Korea: Exochus latiareolus Tolkanitz, 2003, E. ornatus Momoi & Kusigemati, 1970, E. pictus Holmgren, 1858, and E. yasumatsui Momoi, Kusigemati & Nakanishi, 1968. In addition, we provide the diagnoses of these four species along with diagnostic photographs.
