Scape yellowish-brown with apico-dorsal part brown, pedicel dark brown, flagellum dark brown to black. Head black with metallic tinges, clypeus dark brown. Mesoscutum and mesoscutellum black with metallic tinges, propodeum black. Legs with coxae black; trochanters pale brown; femora black; tibiae and tarsi yellowish-brown, T4 dark brown. Petiole yellowish-brown. Gaster black, Gt

Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a weak median groove, with ten scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves distinct, straight and diverging slightly towards posterior part; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with weak sculpture, with median carina. Propodeum with triangular median carina (shaped like an inverted V), concave; callus with seven setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa without carina along posterior margin. Fore wing with 6-7 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a strong transverse carina dorsally and with a median carina in anterior half; tergites with strong reticulation, Gt 2-3 with a very narrow shiny median stripe.
