Cystomastacoides van Achterberg (Braconidae, Rogadinae): first host record and descriptions of three new species from Thailand and Papua New Guinea

A new species of Cystomastacoides van Achterberg, C. asotaphaga Quicke sp. n., is described and illustrated based on a series of specimens reared from caterpillars of the erebid moth Asota plana Walker from Papua New Guinea. Two other new species without biological data are also described, C. nicolepeelerae Quicke & Butcher sp. n. also from Papua New Guinea, and C. kiddo Quicke & Butcher sp. n. from Thailand. A key is provided to the four known species. The new species extend the known range of the genus considerably, it having previously been known only from a single species from mainland China (Yunnan), and additionally provides the first host record for the genus. Other related genera are parasitoids of Sphingidae, Lymantriidae and Crambidae.
