| A revised key to the females of the Palaearctic species of the genus Plectiscidea Viereck, 1914 (Hymenoptera: Ichneumonidae; Oxytorinae) is given. Two new species from Siberia are described: Plectiscidea (Plectiscidea) obscura and P. (P.) spuria. Of P. (P.) subteres (Thomson, 1888) and P. (P.) melanocera (Forster, 1871) a new survey of characters is given. The holotype of Aniseres lubricus Förster, 1871 was re-examined and it is ascertained that it represents a species of Pantisarthrus Förster, 1871. One new species of the genus Aniseres Förster, 1871, is described, A. paradoxus spec, nov., and two new species of the genus Eusterinx Förster: E. (? Holomeristus) similis and E. (? Holomeristus) truculenta. A revised key to the females of the Palaearctic... |

| INTRODUCTION This study was undertaken to prepare keys to the European species of the genus Trychosis Foerster. The older keys by Schmiedeknecht (1890 and 1904-1906), mostly based on Tschek's keys in his study of the genus Cryptus (1870b), do not lead to satisfactory results. This is due to the fact that several characters used by Tschek are not critical, while several of the species described by him have turned out to be identical with others. Nevertheless Tschek's pioneer work in this group deserves our admiration. When I had advanced somewhat with the interpretation of Tschek's type material, I became curious about the species described by some other authors, viz. Thunberg, Gravenhorst and Thomson. I had the opportunity to study some of their type... |
