Information is presented on the large complex of hymenopteran and dipteran parasitoids associated with Uraba lugens Walker (the gumleaf skeletonizer) in South Australia. A key to the 22 species involved is presented, along with notes on identification and relationships with their host. Two species of microgastrine braconids are described, Cotesia urabae sp. nov. and Dolichogenidea eucalypti sp. nov.; both are parasitoids of the larval stages of U. lugens.
