Description of two new Australian genera of Megastigmidae (Hymenoptera, Chalcidoidea) with notes on the biology of the genus Bortesia

Abstract

Two new genera, Striastigmus, gen. nov., and Vitreostigmus, gen. nov., as well as three new species, S. bicoloratus, sp. nov., V. maculatus, sp. nov., and V. kangarooislandi, sp. nov., are described from Australia. A key to species of Vitreostigmus is provided as well as new information on the biology of genus Bortesia. Potential hosts of the newly described genera are discussed.
