Genera Colastes Haliday, Colastinus Belokobylskij, and Xenarcha Foerster (Hymenoptera, Braconidae, Exothecinae) from the Korean Peninsula with a discussion on the Exothecinae genus and subgenus composition
The Exothecinae genera Colastes Haliday, 1833, Colastinus Belokobylskij, 1984, and Xenarcha Foerster, 1863 of the Korean peninsula are reviewed. The names Pseudophanomeris Belokobylskij, 1984 and Shawiana van Achterberg, 1983 are synonymised with the genus Xenarcha Foerster and treated as subgenera. The two new species of Colastes and one new species and subspecies of Xenarcha are described and illustrated. Exothecus effectus Papp, 1972 is included in Xenarcha Foerster, comb. nov. The composition and distribution of the world-known Exothecinae genera are discussed and an illustrated key to its genera and subgenera is presented. A key to the Korean species of the genera Colastes, Xenarcha, and Colastinus is also provided.
