Revision of fossil species of deinodryinus, with description of a new species (Hymenoptera, Dryinidae)

Abstract

Deinodryinus velteni sp. n. is described from middle Eocene Baltic amber. The species differs from other fossil Palaearctic species of Deinodryinus Perkins owing to the shape of the antenna (clavate, with distal part very thickened), the large compound eyes, and the distal part of the stigmal vein much longer than the proximal part. A revision and a key to the fossil Palaearctic species of Deinodryinus Perkins, 1907 is presented. © A. Guglielmino, M. Olmi.
