Two new species of European Microgaster Latreille, 1804 (Hymenoptera: Braconidae, Microgastrinae), with host data on some further species

Abstract

Two new European species of Microgaster are described from reared material. Microgaster nervosae sp. nov. parasitizes Agonopterix species (Depressariidae) on Ulex and Genista in Britain, and a key is provided to separate it from two other British Microgaster species that parasitize other Agonopterix, with host information. Microgaster monetae sp. nov., a parasitoid of Polychrysia monetae (Noctuidae), is described from Austrian specimens. The host repertoires of Microgaster nobilis and M. australis, two European species that are regular parasitoids of Hesperiidae: Pyrginae in the Mediterranean region, are discussed on the basis of reared material in NMS. Some new country records (France, Israel, Portugal, Spain) of already established Microgaster species are given.
