The Banchinae are a large cosmopolitan subfamily that includes approximately 1,800 species in 67 genera. The number of species in South Korea is still pooly known and only 18 of the 312 Eastern Palaearctic species have been reported (Yu et al., 2016). Most species are koinobiont endoparasitoids of lepidopteran larvae and pupae. Teleutaea is a moderately sized genus, comprises 20 described species from Palaearctic, Neotropic and Oriental regions. One species has been described from Mexico. The data of the species from the neighbor countries was summarized as follow: 10 species from Russia (Kuslitzky, 2007); 10 species from Japan (Momoi, 1978; Watanabe & Maeto 2014); 15 species from China continental (Sheng, 2014); three species from Taiwan (Chiu, 1965). Until now the genus was not known from South Korea. Members of this genus parasitize on lepidopterous larvae and pupae living in different kinds of hideaways after than, they emerge from the pupa as adult. As a result, we newly recorded seven species from South Korea including a new species. The key for identification of the South Korean species of Teleutaea and description of a new species are provided.

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.

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.

Monodontomerus Westwood is widely distributed genus in Torymidae Walker, and it consists of 41 species with one fossil species. In Palearctic region, 18 species are recorded, each 5 species are known from Japan and China, and 8 species from Russia. However, in South Korea, only two species are known as follows: Monodontomerus dentipes (Dalman) and M. minor (Ratzeburg). In this study, four species are newly reported and a key to South Korean species of the genus Monodontomerus Westwood, diagnosis, photos of characteristics are provided.

Leucospidae Walker are a relatively small family in Chalcidoidea, and they consist of four genera and about 140 species in worldwide. In neighboring countries, 12 species are known from China and four species are known from Japan, but only one species is known from South Korea by Paik (1974). In this study, Leucospis yasumatsui Habu is reported for the frist time from South Korea. A key to South Korean species of the genus Leucospis Fabricius, diagnosis, photos of characteristics and distribution from South Korea are provided.

Filixungulia, a small genus within the subfamily Allantinae (Symphyta: Tenthredinidae), consists of three species distributed only in Northern China: F. alboclypea Wei, 1997; F. crassitarsata Wei, 1997; F. cylindrica Wei, 2003. It is close to Asiemphytus Malaise and Macremphytus MacGillivray but is separated by the following characteristics: claws simple and very slender; basal lobe and inner tooth absent. Up to date, Filixungulia has not yet been recorded out of China. As a result of the present study, the genus Filixungulia is newly recognized from South Korea with two species, F. alboclypea and F. cylindrica. This discovery extends the range of the genus Filixungulia, which was previously known as a Chinese endemic genus. Also, a key, diagnosis and photographs of each species are 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).

Entomacis, a moderately sized parasitic wasp genus within Diapriidae, consist of 56 species in the world. In East Asia, 11 species are recorded from Japan, 6 species from South Korea and Russia and 4 species from China. In this study, two newly recorded species of the genus Entomacis Förster, 1856 (Hymenoptera: Diaprioidea: Diapriidae), E. laticeps Chemyreva, 2015 and E. penelope Nixon, 1980, are reported from South Korea. A revised identification key to the South Korean species, diagnosis, illustrations and photographs of the diagnostic characteristics are provided herein

Diapriidae are the largest family in Diaprioidea with 2,087 species, 194 genera and three subfamilies that are distributed in all biogeographic regions. Most members of the family are primarily solitary or gregarious endoparasitoids of various dipteran larvae or pupae. Some species are also known to attack hymenopteran, coleopteran and lepidopteran species. To date 18 species in total are known from South Korea. We present an updated checklist of 18 South Korean species of Diapriidae, with correcting some errors previously made. New Korean names for each species are also suggested herein.

Mymaridae, a moderately sized parasitic wasp family within Chalcidoidea, consists of 1,424 species in 103 genera worldwide. In East Asia, 75 species of 20 genera are recorded from China, 40 species of 15 genera Japan and 17 species of 8 genera South Korea. Eubroncus in Mymaridae is newly recognized from South Korea with E. prodigiosus. Redescription and photographs of the diagnostic characters of E. prodigiosus are provided.

Netelia Gray, 1860, a largest genus within the subfamily Tryphoninae and its distribution is worldwide. The members of Netelia are known to be ectoparastic koinobionts of lepidopteran larvae. More than 330 species have so far been recorded and divided into 12 subgenera. Among them, the subgenus Amebachia Uchida, 1928 was reported as a genus by Uchida (1928) based on Amebachia baibarana from Taiwan. The lectotype of Amebachia baibarana Uchida, 1928, was re-examined and then this species should be a subgenus of the genus Netelia by Konishi (2010). Consequently, five currently valid species of Netelia (Amebachia) have been described in the world. As a result of the present study, the subgenus Amebachia belonging to the genus Netelia is reported from South Korea for the first time based on a species of Netelia (Amebachia) rasilella and N. (A.) yoshimatsui. Redescriptions and photographs of the diagnostic characters of two species are provided. This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2016R1A6A3A03007788).
