Diagnosis
Both sexes: Body, including antennae and legs, entirely dark brown. Frontal depression small and nearly flat, transverse carinae absent; submedian carina indicated by weak rugae. Hyperoccipital carina indicated by one or more sharp rugae. Occipital carina incomplete, weakly convex medially; occiput with many transverse rugae. Metascutellum deeply concave, emarginate apically, projecting dorsally. Postmarginal vein absent or extremely short. T1 lateral carina not expanded laterally. Female: A3 longer than pedicel. A4, A5 broader than long. T1 midlobe with 5 longitudinal carinae that may be obscured by a smooth raised area. Fore wing long enough to reach middle of T6 or beyond metasomal apex. T6 broader than long. Male: A4, A11 about as long as broad. T1 midlobe with 4 longitudinal carinae. Fore wing long enough to reach beyond T7. T7 truncate or weakly concave.

Comments
Our concept of this species suggests that it is variable in female metasomal length. The holotype has a shorter metasoma, in which T6 is broader than long, but some specimens have a longer metasoma, where T6 is longer than broad. Specimens of both forms have been found from the same collection events, and some specimens appear to be intermediate between the two states. Several other Australian species are entirely dark brown, but these species differ in many other respects, and do not appear to form a monophyletic group.
