Areopraon chaitophori n. sp (Hymenoptera: Braconidae: Aphidiinae) associated with Chaitophorus leucomelas Koch on poplars, with a key for European Areopraon Mackauer species

Abstract

Areopraon chaitophori n. sp. associated with Chaitophorus leucomelas Koch on Populus nigra is described and illustrated. The main diagnostic characters of Areopraon species are discussed, and a key for identification of European species is provided. The distal dorsal part of the second metasomal tergite of Areopraon species has a very prominent horizontal longitudinal protuberance, which represents a new diagnostic character for Areopraon.
