Rostropria, a new genus of Opisthognathous Diapriine wasp from Australia, and notes on the genus Neurogalesus (Hymenoptera : Proctotrupoidea : Diapriidae)

Abstract

Rostropria, gen. nov., comprising six new species (casta, garbo, gondola, inopicida, simplex and spiniventris) from eastern Australia, is most closely related to Neurogalesus Kieffer. The palpal formula is variable within Rostropria. R. inopicida is a parasite of the sugarcane soldier fly, Inopus rubriceps (Macquart) (Stratiomyidae), and a potential biological control agent for this pest of pastures and sugar cane. Euhoplopria Dodd is synonymised with Neurogalesus and the three described species (E. carinatifrons Dodd, E. lativentris Dodd, E. emargipennis Dodd) are transferred to Neurogalesus.
