Head brown, paler around eyes; anterior half of antenna light brown, posterior half dark brown; mesosoma black; wings with long brown hair given a smoky appearance of the wings, with a white band underneath the parastigma; legs white, with femur and apical end of tibia brown; anterior end of carapace white, extending dorsal into the posterior dark end. Male. Head beige; antenna light brown; mesosoma black; legs as female but paler; wings infuscate; wing venation brown; metasoma anterior half white, posterior half black. Diagnosis Females differ from all other described Ascogaster in Australia by having a reduced SR-1 vein (not extending to the margin of the fore wing).
