  • A new species, Venturia tenuiabdominalis Choi sp. nov., belonging to the subfamily Campopleginae, family Ichneumonidae, is described in South Korea. The subfamily Campopleginae was recorded by Forster in 1869 based on genus Campoplex and more than 2,100 described species into 66 genera have been reported worldwide. Among the 66 genera of Campopleginae, the genus Venturia is one of the large groups, which is more than 140 species worldwide (Yu et al., 2016; Vas, 2019a; 2019b; Vas, 2020; Vas and Di Giovanni, 2020; Han et al., 2021). A taxonomic study of South Korean Venturia was initiated by Choi et al. (2012), who reported Venturia longipropodeum (Uchida, 1942). A key to species of South Korean Venturia, description of new species and diagnostic illustrations are provided.

  • Species of the genus Eopompilus Gussakovskij, 1932 from South Korea are reviewed. Three species are confirmed: E. internalis, E. luteus, and E. minor. Eopompilus luteus is recorded for the first time in Korea, and is easily separated from its congers by markedly extensive coloration and comparatively large body size in both sexes. Females are characterized by yellowish wing, light brown stigma and veins, lacking of subapical or apical dark fascia on forewing. Males are characterized by serrate antenna formed by submesal convex on each flagellomeres 2-11, symmetrical claws of fore tarsus, hypopygium widened basally and forming a rhomboid plate, lacking of dark fasciae in forewing. The specimen identified as Cryptocheilus nicevilli Bingham from Korea by Kim (1970) is examined and is reclassified as conspecific with E. luteus. A key is presented of the three species complemented by digital images and diagnosis.

  • A new species, Monoblastus forsythia sp. nov. is described from South Korea. All specimens of this new species were collected on Forsythia koreana (Nakai). A taxonomic study of South Korean Monoblastus was initiated by Uchida in 1930, and until now four species have been recorded from South Korea. The genus Monoblastus is a Holarctic genus with 31 described species, 14 species are Nearctic, seven are Western Palaearctic region, and nine species occur in Eastern Palaearctic region. In the study, I provide description and photos of both sexes of this new species. Also, modified key to species of the South Korean Monoblastus is provided.

  • We report the unrecorded genus and species, Notopygus emarginatus Holmgren, 1857, for the first time from South Korea. The genus Notopygus is a parasitoid wasp of Pamphiliidae (sawfly) that can be distinguished by the posterior margin of metasomal tergite eight, which frequently project strongly upwards. In the study, we provide a description and photographs of newly recorded species.

  • Four species, Colpotrochia bifasciata, C. munda, C. pilosa sinensis, and C. uchidai, are newly recognized in South Korea. The genus Colpotrochia Holmgren, 1856 is a large group of the subfamily Metopiinae, in Ichneumonidae, and contains 62 described species worldwide. Among them, nine species have been recorded from South Korea. The South Korean Colpotrochia was started from by Uchida in 1930. A comprehensive historical review of the faunal study of this genus in South Korea have been done by Kim and Japanese entomologists in the period of 1955-1966. In this study, diagnoses of four unrecorded species and illustrations of diagnostic characters are provided. The current total is 13 species of this genus known from South Korea.

  • Halictidae is a large group with more than 3,500 species found worldwide. They are called sweat bees because they are attracted to people's sweat. In this study, Halictus hedini hedini Blüthgen, 1934, belonging to Halictidae, is reported for the first time in Korea. Description, distribution, and illustration of this species are provided.

  • A total of 12 species in six genera of the poneromorph subfamilies group in Korea was reviewed. All investigated specimens are classified into three subfamilies; Amblyoponinae, Proceratinae and Ponerinae. Totally six genera were known and Cryptopone, Hypoponera, Pachycondyla and Ponera belong to the subfamily Ponerinae and Amblyopone and Proceratium belongs to the subfamily Amblyoponinae and Proceratinae respectively. In this study, keys to the all known genera and species of the subfamilies in Korea are presented. A synonymic list, description of a worker and comments on each species are given with SEM photographs of worker.

  • The genus Metopius is a relatively large ichneumonids group that includes 145 species worldwide. In this genus, 41 species have been reported from the Eastern Palaearctic region, while eight species have been reported from Korea. We reviewed Korean species of the genus Metopius and confirmed 13 species. We also report five species, Metopius (Ceratopius) maruyamensis Uchida, 1930, Metopius (Ceratopius) scrobiculatus Hartig, 1838, Metopius (Peltastes) fossulatus Uchida, 1933, Metopius (Peltastes) pinatorius $Brull{\acute{e}}$, 1846 and Metopius (Peltastes) sapporensis Uchida, 1930, which were recorded for the first time from Korea. A key to Korean species of the genus Metopius, redescriptions of newly recorded species and digital images of Korean Metopius are also provided.

  • An effective pollinator was investigated based on visiting insects to confirm the pollination mechanism of Impatiens furcillata Hemsl. (cheo-jin-mul-bong-seon), an annual herb that is also a species endemic to Korea that has hardly been studied in relation to pollination ecology. The insects that visited the group of I. furcillata studied here consisted of four orders, 11 families, and 16 species; Hymenoptera had seven species (43.8%), Lepidoptera had four (25.0%), Diptera four (25.0%), and Hemiptera one (6.2%). Visiting insects were divided into those that took only nectar, those that took nectar and pollen, and those that took neither. Insects that are effective for pollination are judged considering the length and body type of their mouth parts, and Amegilla florea Smith (huin-jul-beol) is judged to be the most effective pollinator in the survey area. As a result of observing pollination behavior, when visiting a flower, A. florea, which extended its glossa, approached the front, landed on a wing petal of I. furcillata, crawled into the flower tube, and then backed up and reversed its steps, with pollen adhered to its back. The findings here present basic information about species biology related to both I. furcillata and A. florea.
