Two unrecorded species, Brachynervus beijingensis and B. confusus are described from South Korea for the first time. A taxonomic study of the South Korean Brachynervus was initiated by Uchida (1955). Until now only one species, B. tsunekii, has been recorded from South Korea. In the study, we provide the diagnoses and photos of two unrecorded species of Brachynervus.

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.

Antheraea mylitta Drury is a commercial silk producing forest insect in India and Xanthopimpla pedator Fabricius is its larval-pupal endoparasitoid, which causes pupal mortality that affects seed production. Effects of host plants, rearing season and their interactions on parasitic behaviour of X. pedator were studied here, as influence of these factors on biological success of X. pedator is not known. Seven forest tree species were tested as food plants for A. mylitta, and rate of pupal parasitization in both the rearing seasons were recorded and analysed. Results showed that rearing season and host plants significantly affected the rate of pupal parasitization in both the sexes. Pupal mortality was found significantly higher (14.52%) in second rearing season than the first (2.89%). Likewise, host plants and rearing seasons significantly affected length, diameter, and shell thickness of cocoons in both sexes. Out of all infested pupae, 85.59% were found male, which indicated that X. pedator chooses male spinning larva of A. mylitta for oviposition, but we could not answer satisfactorily the why and how aspect of this sex specific parasitic behaviour of X. pedator. Multiple regression analysis indicated that length and shell thickness of male cocoons are potential predictors for pupal parasitization rate of X. pedator. Based on highest cocoon productivity and lowest pupal mortality, Terminalia alata, T. tomentosa, and T. arjuna were found to be the most suitable host plants for forest based commercial rearing of A. mylitta in tropical forest areas of Uttarakhand state, where it has never been reared earlier. Sex and season specific interaction of X. pedator with its larval-pupal host, A. mylitta is a novel entomological study to find out explanations for some of the unresolved research questions on parasitic behaviour of X. predator that opens a new area for specialised study on male specific parasitization in Ichneumonidae.

Previously, only one species belonging to the genus Apophua was recorded from South Korea by Kim (1955). Here, six additional species, A. cicatricosa, A. evanescens, A. honmai, A. stena, A. sugaharai and A. tobensis, are reported for the first time in South Korea. In this paper, we provide a key to the Eastern Palaearctic species of Apophua and diagnoses, as well as photographs of South Korean species.

This study was aimed to clarify the morphological and ecological characteristics of Dolichomitus cephalotes and Dolichomitus curticornis in order to provide basic data to be used for biological control against Monochamus saltuarius. D. cephalotes and D. curticornis are univioltine in the central region of Korea and overwinters as larval stage inside the cocoon. Both species are ectoparasitoid, and a solitary parasitoid. D. cephalotes adults are emerged from the beginning of April to the middle of May, while D. curticornis adults are emerged from late April to mid-May.

We reviewed eight South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869. Among them, the Genus Scambus Hartig, 1838 is a moderately large group that includes 152 species worldwide. The South Korean genus Scambus Hartig, 1838 only includes one species, Scambus calobatus (Gravenhorst, 1829). The Tromatobia $F{\ddot{o}}rster$, 1869 group is a relatively small genus, including 33 worldwide species. This group is recorded for the first time from South Korea. Also, we report seven newly recorded species: Scambus nigricans (Thomson, 1877), Scambus vesicarius (Ratzeburg, 1844), Tromatobia flavistellata Uchida and Momoi, 1957, Tromatobia nipponica Uchida, 1928, Tromatobia ornata (Gravenhorst, 1829), Tromatobia ovivora (Boheman, 1821), and Tromatobia variabilis (Holmgren, 1856). A key to South Korean species of the genera Scambus Hartig, 1838 and Tromatobia $F{\ddot{o}}rster$, 1869, diagnoses and illustrations are provided.

We report twenty eight ichneumonid species new to Korea. These species belong to seven subfamilies. Among them five subfamilies, Diacritinae Townes, 1965, Microleptinae Townes, 1958, Orthocentrinae F$\ddot{o} $rster, 1869, Orthopelmatinae Schmiedeknecht, 1910, Phrudinae Townes and Townes, 1949, are newly introduced to Korean fauna. All specimens are based on the insect collection of animal systematic laboratory at the Yeungnam University Gyeongsan Campus. Photographs of habitus of newly recorded subfamilies, diagnosis of 28 species and host information are provided.

The Palaearctic species of the genus Trathala Cameron are reviewed. Genus Trathala is the third largest group. This genus was described Trathala striata by Cameron for the first time in the world. One hundred one species of this genus have been recorded worldwide. Trathala flavoorbitalis Cameron and Trathala hierochontica (Schmiedeknecht) were recorded from Palaearctic. Here we report three species, Trathala flavoorbitalis Cameron, Trathala hierochontica (Schmiedeknecht) and Trathala striata Cameron, from Palaearctic region. Among them, Trathala striata Cameron is a newly recorded species for the first time from Palaearctic region and South Korea. Redescriptions of Palaearctic Tranthala species with photographs and a key to the Palaearctic Trathala species are provided.

The genus Delomerista Förster, 1869 is a small group that includes 18 species worldwide that, for the first time, has been recorded from South Korea. Iseropus Förster, 1869 is a small group that includes nine species worldwide. The genus Perithous Holmgren, 1859 is also small group including 18 species worldwide. In this study, keys to species of these genera and illustrations and diagnoses of each species are provided.
