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

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