All coxae and all femora brown; tibiae and tarsi yellowish-brown. Fore wing slightly infuscate, venation yellowish-brown. Metasoma dark brown, in dorsal view Mt2-Mt4 metallic blue-green with diffuse coppery lustre.

Sculpture. Head in frontal view reticulate, head in dorsal view and clypeus smooth and shiny; mesosoma reticulate, but frenum finely reticulate; dorsellum alutaceous, with distinct upper and lower crenulate cross-line; propodeum weakly reticulate; metasoma weakly alutaceous and shiny.
