Revision of the European species of Torymus Dalman (Hymenoptera: Torymidae)

In this revision the generic synonymy as proposed by Grissell (1976, 1995) is followed. The genus Diomorus Walker is here synonymised with Torymus as well, so that the tribe Torymini (sensu Grissell) includes only one genus in the West Palaearctic region. In Torymus, 154 species are recognised, 38 of which are here described as new. The existing types of nearly all names have been examined and 272 synonyms, 67 of them new, are listed. The genus is subdivided in 13 species groups, five species standing apart as species solae. Keys to the species groups, females and more distinctive males are presented.
