Descriptions of adults, immature stages and venom apparatus of two new species of Eudinostigma Tobias (Hymenoptera, Braconidae), hyperparasitoids of Phryxe caudata (Rondani) (Diptera, Tachinidae)

Abstract

The imagines and cast skin of the final larval instar of two new species of Alysiini from Spain, hyperparasitoids of Phryxe caudata (Rondani), Eudinostigma bienesae Fischer, Tormos & Pardo, sp. n. and Eudinostigma planiceps Fischer, Tormos & Pardo, sp. n., and the venom apparatus of E. bienesae Fischer, Tormos & Pardo, sp. n. are described, illustrated, and compared with those of allied species. The morphological structures of phylogenetic value are discussed, and keys for the discrimination of the imagines are provided.
