Review of subfamily Diplazontinae (Hymenoptera: Ichneumonidae) from South Korea with six unrecorded genera and a new species

Of the 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 genera are recognized from South Korea. Specifically, four genera (Campocraspedon Uchida, Diplazon Nees, Syrphoctonus Förster and Woldstedtius Carlson) are previously recognized from South Korea, whereas the other seven genera are recorded from this country for the first time. A key to the 16 genera of Diplazontinae occurring in the Eastern Palearctic region is provided. Six genera of Korean Diplazontinae (Bioblapsis Förster, Campocraspedon Uchida, Eurytyloides Nakanishi, Phthorima Förster, Promethes Förster and Sussaba Cameron) are reviewed here. Species of these genera rarely occur in the Eastern Palearctic region with small numbers of collected samples (excluding genus Sussaba). Here we provide diagnosis for seven species of Diplazontinae and one new species, Eurytyloides koreanus Balueva and Lee sp. nov. , has been described.     

Two new species of the genus Probles Förster (Hymenoptera: Ichneumonidae: Tersilochinae) from South Korea and Russian Far East

Two species of the genus Probles Förster, P. interruptor sp . nov . and P. segaza sp . nov ., from South Korea and Russian Far East, are described. Probles interruptor differs from its congeners by occipital carina mediodorsally narrowly interrupted and polished occipital surface extending partly on the vertex. Probles segaza differs from other species of Euporizon by its robust ovipositor with a deep and narrow dorsal subapical notch.     

Study on two genera,Yasumatsua Togashi and Aproceros Malaise (Hymenoptera: Argidae: Sterictiphorinae), from South Korea with description of a new species

Yasumatsusa Togashi, 1970 and Aproceros Malaise, 1931 are recorded for the first time from South Korea. A new species, Yasumatsua koreana Lee & Lee sp. nov., and newly recorded species, Aproceros pallidicornis (Mocsáry, 1909), are described. Photographs of the new species and a key to genera of Korean Sterictiphorinae are provided.     

Study on four genera of Diplazontinae (Hymenoptera: Ichneumonidae) in South Korea with description of two new species

Of 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 were previously recognized from South Korea. In previous studies we reviewed eight Diplazontinae genera were reviewed. In this current paper, one genus, Enizemum Förster, is recorded from this country for the first time with one newly described species, E. nigrocoxatum Balueva and Lee sp. nov. Also other three genera, Homotropus Förster, Syrphoctonus Förster and Syrphophilus Dasch, are reviewed here. Here we provide key and diagnosis to eight species of Homotropus including one new species, Homotropus sepiatus Balueva and Lee sp. nov. , and key and diagnosis to two species of genus Syrphoctonus and two species of genus Syrphophilus.     

A review of the genera Gnathochorisis F?rster and Symplecis F?rster of South Korea,with notes on Korean orthocentrines (Hymenoptera,Ichneumonidae, Orthocentrinae)

Two genera of Korean Orthocentrinae, Gnathochorisis and Symplecis, are reviewed, and keys to species of these genera are provided here. Two new species, Gnathochorisis fuscipes Humala & Lee, sp. n. and Gnathochorisis koreensis Humala & Lee, sp. n. are described from South Korea. The current state of the taxonomy of Eastern Palaearctic orthocentrines is briefly discussed.     

Review of the genus Eusterinx Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) with descriptions of five new species from South Korea

South Korean species of the genus Eusterinx Förster are reviewed here. Nine species of the genus Eusterinx are found to occur in South Korea, and five species, Eusterinx (E.) elongata sp. nov. , E. (Holomeristus) hirtis sp. nov. , E. (Ischyracis) fulvipes sp. nov. , E. (I.) petiolata sp. nov. and E. (I.) rufithorax sp. nov. , are described. Four more species of Eusterinx from subgenera Divinatrix, Eusterinx and Holomeristus are recorded from South Korea for the first time. Hitherto, unknown male of the Eastern Palaearctic species E. (Divinatrix) kurilensis Humala is described. A key to all known species of the genus Eusterinx occurring in South Korea is provided.     

Two Unrecorded Species of the Genus Enicospilus (Hymenoptera: Ichneumonidae: Ophioninae: Enicospilini) from Korea

ABSTRACT Two Enicospilus species, E. melanocarpus Cameron and E. pseudoconspersae (Sonan), are newly recorded in Korea. A revised key on the whole known Korean species including above two species are presented.     

韩国黄蚜小蜂属分类研究(膜翅目:蚜小蜂科)

本文报道采自韩国的黄蚜小蜂属5种,包括1新种（Aphytis albus,sp．nov．)及4个韩国新记录种(Adiaspidis,A.japonicus,Aproclia和Avandenboschi),编制了雌成虫检索表。新种模式标本保存在韩国国立树木园和东北林业大学昆虫标本室。     

A new species of the genus Seticornuta Morley (Hymenoptera,Ichneumonidae, Metopiinae) from South Korea

Old World species of the genus Seticornuta Morley are reviewed. Seven species of this genus were recorded worldwide, but only one species, Seticornuta albopilosa (Cameron), was known from the Old World. Here, we report one new species, Seticornuta koreana sp. n., from South Korea, and redescribe the other known Old World species, Seticornuta albopilosa, with photographs.
