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.The work conducted in ZMUT was partly financed by the Kone Foundation (Finland) research project “Biodiversity and multitrophic interactions” granted to IES
