Redescription of species of the Neotropical parasitoid Notiospathius Mathews et Marsh (Braconidae: Doryctinae) based on their nineteenth and early twentieth century types

Seven species of the speciose Neotropical parasitoid wasp genus Notiospathius Mathews et Marsh are redescribed. These species were originally described during the nineteenth and early twentieth centuries. Examination of the holotpyes of N. meliorator and N. necator revealed that they actually belong to an undescribed doryctine genus that is similar to Ptesimogaster Marsh, 1965. A key is provided to distinguish these species.
