Review of the East Palaearctic and North Oriental Psyttalia Walker, with the description of three new species (Hymenoptera, Braconidae, Opiinae)

Abstract. The East Palaearctic and North Oriental species of the genus Psyttalia Walker (Hymenoptera, Braconidae, Opiinae) are reviewed. Three new species are described and illustrated: Psyttalia latinervis Wu & van Achterberg, sp. n. and Psyttalia majocellata Wu & van Achterberg, sp. n. from China, and Psyttalia spectabilis van Achterberg, sp. n. from Japan. Coeloreuteus formosanus Watanabe, 1934, Opius (Lissosema) proclivis Papp, 1981, Opius (Psyttalia) subcyclogaster Tobias, 1998, Opius (Psyttalia) darasunicus Tobias, 1998, Opius (Psyttalia) cyclogastroides Tobias, 1998, Psyttalia extensa Weng & Chen, 2001, and Rhogadopsis longicaudifera Li & van Achterberg, 2013, are new synonyms of Psyttalia cyclogaster (Thomson, 1895); Opius (Psyttalia) ophthalmicus Tobias, 1977, and Opius (Psyttalia) brevitemporalis Tobias, 1998, of Psyttalia carinata (Thomson, 1895) and both Opius (Psyttalia) vacuus Tobias, 1998, and Opius (Lissosema) longurius Chen & Weng, 1995, of Rhogadopsis mediocarinata (Fischer, 1963). Phaedrotoma daghestanicum (Telenga, 1950), Rhogadopsis mediocarinata (Fischer, 1963) and Rhogadopsis mystica (Fischer, 1963) are new combinations. New records are Psyttalia carinata (Thomson, 1895) from The Netherlands and Norway, and Psyttalia cyclogaster (Thomson, 1895) from Japan. A lectotype is designated for Psyttalia carinata (Thomson, 1895) and Psyttalia cyclogaster (Thomson, 1895). A key to the East Palaearctic and North Oriental species of the genus Psyttalia Walker is included.
