Review of the Palaearctic Trathala Species (Hymenoptera: Ichneumonidae: Cremastinae)

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.

Two New Records of the Ichneumonidae (Hymenoptera) Species from Korea

Previously, 13 species in six genera of the subfamily Banchinae and 29 speices in 16 genera of the subfamily Pimplinae were known from Korea. In this paper, two species, Rynchobanchus minomensis (Uchida, 1933) and Theronia laevigata nigra Uchida, 1928 are new to Korea. Also, the genus Rynchobanchus is recorded for the first time in Korea. Only one species of Theronia, Theronia atalantae (Poda, 1761), was recorded from Korea by Uchida (1928). New Korean names proposed for these two species are “Eol-gul-ga-si-maep-si-beol” and “Geom-jeong-nap-jak-maep-si-beol” for the R. minomensis and T. laevigata nigra, respectively. A key to the species of Theronia, diagnosis and photographs of diagnostic characters of them are provided.

Review of the Genus Hypsicera (Hymenoptera: Ichneumonidae: Metopiinae) from South Korea

Hypsicera has been reported six species from South Korea. In this study, we reviewed 13 species of South Korean Hypsicera including seven newly recorded species from South Korea. Female of H. brevicornis and H. nigribasis are reported for the first time from South Korea since first record. Additionally, H. incarinata and H. yoshimoboi are reported new to China. We provide diagnoses of six newly recorded species and descriptions of two new females. We also provide photographs of key characters of seven newly recorded species and a key to 13 species of South Korean Hypsicera.

A new species of Monoblastus Hartig, 1837 (Hymenoptera: Ichneumonidae: Tryphoninae) from South Korea

A new ichneumonid species, Monoblastus koreensis sp. nov. is described from South Korea. New data on the taxonomy and distribution of M. clauseni (Uchida), M. erythrurus Townes et al. and M. nigriventus Lee Cha are given. The taxonomic position of M. nigriventus and its similarity to M. ermolenkoi Kasparyan from Russian Kuril Islands is discussed. All these species are keyed and illustrated. Erromenus alpinator Aubert sensu Lee Cha (= Monoblastus koreensis sp. nov.) is excluded from the fauna of South Korea.

Two new species of Leptobatopsis Ashmead (Hymenoptera: Ichneumonidae: Banchinae) from South Korea and gynandromorphy in L. nigricapitis.

Four species of Leptobatopsis Ashmead are recorded for the first time from South Korea. Among them, L. koreana sp. nov. and L. daedeokensis sp. nov. are newly described. We also report two newly recorded species, L. nigricapitis Chandra & Gupta and L. appendiculata Momoi, from South Korea. In addition, we describe a case of gynandromorphy of L. nigricapitis in a single specimen from South Korea. This specimen presents bilateral asymmetry, with the left half of its habitus displaying male characters and the right half displaying female characters. We also provide a key to Eastern Palaearctic species of Leptobatopsis.

Three New records of the Genera Cremastus and Pristomerus (Hymenoptera, Ichneumonidae, Cremastinae) from South Korea

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.
