Clistopyga caramba sp. nov. (Hymenoptera: Ichneumonidae; Pimplinae), an astonishing example of mimicry in spider-attacking parasitoid wasps.

Clistopyga caramba sp. nov. Castillo & Sääksjärvi, collected from the tropical Andean-Amazonian interface in Peru, is described and illustrated. The new species is characterized by highly modified posterior metasomal tergites and a rare colour pattern of the metasoma. Two possible explanations for the bizarre metasomal morphology and colouration are proposed.
