Study on two unrecorded genera,Barycnemis Förster and Phradis Förster (Hymenoptera: Ichneumonidae: Tersilochinae), from South Korea

Six genera of the subfamily Tersilochinae (Barycnemis, Diaparsis, Gelanes, Phradis, Probles and Tersilochus) are recognized in South Korea. Two genera, Diaparsis and Tersilochus, were previously recognized from South Korea, whereas the other four genera are recorded from this country for the first time. All genera found in South Korea, except the almost cosmopolitan Diaparsis, are entirely or predominantly Holarctic. A key to the six genera of Tersilochine occurring in South Korea is provided. Two genera of Korean Tersilochinae (Barycnemis and Phradis) are reviewed here, and a key to the other four species (B. bellator, B. dissimilis, P. kyushuensis and P. nikishenae) is provided in this paper.     

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.     

Mexican species of the genus Stethantyx Townes (Hymenoptera,Ichneumonidae, Tersilochinae)

Six species of the genus Stethantyx Townes are found to occur in Mexico. One species, S. mexicana sp. n., is described as new, and four recently described Neotropical species, S. alajuela Khalaim & Broad, S. heredia Khalaim & Broad, S. osa Khalaim & Broad and S. sanjosea Khalaim & Broad, are new records from Mexico. A key to species of Stethantyx occurring in Mexico is provided.     

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.     

First record of Stigmatijanus Wei (Hymenoptera: Cephidae)from South Korea with description of a new species

The genus Stigmatijanus Wei, 2007 is recorded from Korea for the first time. A diagnosis of the genus is briefly discussed. A new species, Stigmatijanus koreanus sp. nov., is described from Mt. Homyeong, Gyeonggi-do, South Korea. A key to the three species of the genus is provided.     

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.

A new genus and species of Metopiinae (Hymenoptera, Ichneumonidae) from Mexico

A new genus of Metopiinae, Ojuelos Khalaim, gen. n., with a single species, Ojuelos juachicus Khalaim & Ruíz-Cancino, sp. n., is described from Jalisco Province in central Mexico. Ojuelos belongs to the group of three genera (Cubus Townes & Townes, Colpotrochia Holmgren and Triclistus Förster) having a high lamella separating the antennal sockets and reaching the median ocellus (this lamella possesses a dorsal groove in it, just below the median ocellus), but differs from these genera primarily by 1) face and clypeus not convex in lateral view, 2) face separated from clypeus by a shallow transverse impression, 3) mandible with lower tooth very strongly reduced, 4) flagellomeres of antenna strongly transverse, and 5) dorsal carinae of propodeum reduced. A portion of the key to the genera of Metopiinae is provided to distinguish the new genus.     

Discovery of the genus Meggoleus Townes, 1971 (Hymenoptera, Ichneumonidae, Tersilochinae) in Peru, with the description of two new species

The genus Meggoleus Townes, 1971 (Ichneumonidae, Tersilochinae) currently comprises two species, one from Brazil and one from Gabon. The genus is recorded from Peru for the first time, with a range extension of the type species, Meggoleus spirator Townes, 1971, and the discovery of two new species - Meggoleus fuscatussp. n. and Meggoleus pampahermosensissp. n. A key to the world's species is 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.
