Keys to the genera and species are provided. Fifty-four species are recognized as valid, 11 are newly synonymized, and 11, including an extralimital species from Jordan, are described as new. Lectotypes are designated for 13 nominal species. Authentic host records are included together with an account of the biology of the subfamily. Introduction Although the braconid subfamily Agathidinae has a world-wide distribution, it is poorly represented in the western Palaearctic region. The present revision deals with the fauna of Europe, including European U.S.S.R., and Turkey; one species from Jordan is included for comparative purposes. Earlier contributions to the taxonomy of European Agathidinae are those of Nees von Esenbeck (1834), Wesmael (1837), Reinhard (1867), Thomson (1895), Marshall (1885; 1888) and Fahringer (1937). The more recent, notable taxonomic revisions on Palaearctic Agathidinae are those of Telenga (1955) and Tobias (1976<z), the former concentrating on the European species, the latter on the Central Asian species. Their combined research reveals an agathidine fauna that hardly differs numerically from that covered in the present work. Even Tobias's paper (19766) on the Far Eastern species of Microdus includes only four that are not represented in Europe. The Agathidinae is well represented in the tropics and Shenefelt's catalogue (1970) lists Bull. Br. Mus. not. Hist. (Ent.) 52 (3): 183-242 Issued 24 April 1986
