Review of the Swedish species of Coleocentrus Gravenhorst, 1829 (Hymenoptera: Ichneumonidae: Acaenitinae) with an illustrated key to the Western Palearctic species

Abstract

The Swedish species of Coleocentrus Gravenhorst, 1829 are revised and the study recognises five species as occurring in Sweden. Coleocentrus borcei Constantineanu, 1929 syn. nov. is synonymised with Coleocentrus soleatus Gravenhorst, 1829 and Coleocentrus soldanskii Bishoff, 1915 syn. nov. is synonymised with Coleocentrus heteropus Thomson, 1894. Coleocentrus exareolatus Kriechbaumer, 1894 and C. soleatus (Gravenhorst, 1829) are presented as new to Sweden, while Coleocentrus croceicornis (Gravenhorst, 1829) and the herein synonymized C. soldanskii are excluded from the Swedish checklist. An illustrated key to the Western Palaearctic species is provided.
