Head with frons metal- lic bluish-green with scrobes black with metallic tinges and clypeus dark brown; vertex black with metallic blue tinges. Mesoscutum black with golden-green tinges, mesoscutellum and propodeum golden-green. Legs with coxae yellowish-brown, fore coxa with very base and hind coxa with basal half dark brown; trochanters, femora, tibiae and tarsi yellowish-brown, T4 pale brown. Petiole black. Gaster with Gt 1 metallic bluish-green with posterior margin metallic purple, Gt2-5 metallic purple, Gt6-7 black; gonoplac black.

Mesoscutellum with submedian grooves with outer margin missing, median part with very weak reticulation, lateral parts rugose with 16 scattered setae. Dorsellum with weak sculpture, with median carina. Propodeum with a strong median carina that is expanded posteriorly; with strong irregular carinae and strong reticulation; callus with four setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with six setae on dorsal surface of submarginal vein; speculum open below (apical seta absent); costal setal row unbroken.
