Illustrated key to the European genera of Opiinae (Hymenoptera, Braconidae), with the description of two new Palaearctic genera and two new species.

ABSTRACT

An illustrated key to the European genera of the subfamily Opiinae (Hymenoptera, Braconidae) is presented and two new genera are described and illustrated Cavopiusgen. nov. (type species Opius (Agnopius) daghoides Zaykov & Fischer, 1983) from West and East Palaearctic regions and Pseudosteresgen. nov. (type species Biosteresadanaensis Fischer & Beyarslan, 2005) from West Palaearctic region. Two new species are described and illustrated Cephaloplitesgijswijtisp. nov. from Greece and Cavopiusdepressoriussp. nov. from S. Korea. Opius (Hypocynodus) kilisanus Fischer & Beyarslan, 2005 is a new synonym of Cephaloplitesmocsaryi Szépligeti, 1897. The following new combinations are proposed Cavopiusdaghestanicus (Telenga, 1950), comb. nov., C.daghoides (Zaykov & Fischer, 1983), comb. nov., Pseudosteresadanaensis (Fischer & Beyarslan, 2005), comb. nov., P.arenaceus (Jakimavicius, 1986), comb. nov., P.christenseni (Papp, 1982), comb. nov., P.pseudarenaceus (Fischer & Beyarslan, 2005), comb. nov., and P.riphaeus (Tobias, 1986), comb. nov. Keys to species are provided for Cavopiusgen. nov., Cephaloplites Szépligeti, 1897, and Pseudosteresgen. nov.
