Two new species of Xanthopimpla (Hymenoptera: Ichneumonidae) from Western Amazonia, with a revised key to the Neotropical species of the genus

Abstract

Xanthopimpla Saussure, 1892 is one of the largest genera of the family Ichneumonidae. The genus is very species rich in Indo-Australia but poorly represented in the Neotropical region. In this paper two morphologically very distinctive species of the genus, X. amazonica sp.n. Gómez, Sääksjärvi & Veijalainen, and X. jussilai sp.n. Veijalainen, Sääksjärvi & Broad, are described and illustrated. The new species have been collected in the Peruvian and Ecuadorean Amazonia. A revised key to the Neotropical species of the genus is provided. X. aurita Krieger and X. craspedoptera Krieger are recorded for the first time from Peru.
