Stenomacrus deletus (Thomson, 1897), belonging to Orthocentrinae of Ichneumonidae, is newly recognized in South Korea. Most Stenomacrus species are known as koinobiont endoparasitoids of dipteran, lepidopteran, and coleopteran hosts. In this study, an additional species is recorded for the first time from South Korea. Diagnoses of genus and an unrecorded species, as well as illustrations of this species are provided.

This paper reports new hosts for three ichneumonids (Apophua evanescens evanescens, Teleutaea minamikawai, and Trathala flavoorbitalis) from South Korea. These three species were discovered from the lepidopteran pupae, viz., Cleora leucophaea (Butler) (Geometridae), Adoxophyes honmai Yasuda (Tortricidae), and Pyrausta phoenicealis (Hübner) (Crambidae), respectively. Among these, the lepidopteran family Geometridae and Crambidae are also newly recorded as host groups for the genera Apophua and Trathala.

According to zoogeographic analysis, distribution types of Korean species of the subfamily Tryphoninae are as follows; Holarctic species (9.6%), Transpalearctic (38.4%), Transpalearctic-Oriental (8.2%), Eastern Palearctic (Trans-Far East Asia)-Oriental (4.1 %), Eastern Palearctic (17.8%) and Endemic (21.9%). Because of large numbers of palearctic and endemic species, we believe that the Korean Tryphoninae may have originated from northern hemisphere. The oldest fossil species of the Tryphoninae are the Catachoru rninor Townes and Urotryphon pusillus Townes in Creataceous amber from the peninsula Taimyr, Siberia. The world-wide distribution of the Tryphoninae appears to coincide with the continental movement.

We report new host records of four ichneumonids from Korea. They were discovered from the pupae of Apatura metis Frever (Lepidoptera: Nymphalidae), Allotraeus sphaerioninus Bates (Coleoptera: Cerambycidae) and Ivela auripes (Butler) (Lepidoptera: Lymantriidae) respectively. Diagnoses, illustrations, host records of the four species, and a list of ichneumon species parasitizing of I. auripes are provided.

The Korean species of the genera Cremastus Gravenhorst, 1829 and Pristomerus Curtis, 1836 (Hymenoptera: Ichneumonidae) are studied. Here we report three species, Cremastus crassitibialis Uchida, 1940, Pristomerus rufiabdominalis Uchida, 1928 and P. scutellaris Uchida, 1932, new to South Korea. Among them genus Cremastus is recorded for the first time from South Korea. The number of Korean Cremastinae is now 11 species in four genera including the three newly recorded species. A key to the genera of Korean Cremastinae, diagnosis of newly recorded species and photographs of redescriptions characters are provided.

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.

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.

A taxonomic study was carried out to discover unrecorded species of South Korean Exetastes of which six taxa were previously known. In the present study, another six taxa were newly recognized from the country: E. adpressorius, E. allopus, E. fukuchiyamanus, E. illyricus, E. sapponensis and E. tomentosus. With the result of this study, 11 species and one subspecies in Exetastes are in total known from South Korea. In addition, a key to the South Korean species and the diagnoses and digital images of the six newly recorded species are provided.
