The gorytine wasps comprise the tribe Gorytini of the sphecid subfamily Nyssoninae. They are a generalized group and all the higher Nyssoninae could have arisen from a gorytine ancestor (Bohart and Menke. 1976). Our knowledge of their ethology has been summarized by Evans (1966) and is based largely on studies in the Northern Hemisphere. Biologically these wasps are little known in the tropics or south temperate regions, although some recent observations have been made in Australia and Argentina (Evans and Matthews, 1971, 1973). The nests are mass-provisioned with Homoptera, mainly Fulgoroidea, Cicadidae, Cicadellidae, Cercopidae and Membracidae. and, in Australia, Eurymelidae, but there are few records of the prey of tropical species.
