Mesoscutum and mesoscutellum black with metallic bluish tinges, propodeum black. Legs with coxae black, hind coxa with metallic blue tinges; trochanters dark brown; femora dark brown to black; tibiae and tarsi yellowish-white, T4 dark brown. Petiole dark yellowish-brown. Gaster black, Gt 1 with metallic bluish tinges, Gt 2-5 with metallic purplish tinges; gonoplac black.

Antenna with ±solid clava. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation, meshes transverse.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with median line indicated through changes in the reticulation, and with six setae in two rows close to notauli. Mesoscutellum with strong reticulation, meshes very elongate; submedian grooves distinct, straight and diverging slightly towards posterior part; anterior pair of setae placed in the anterior one-third of mesoscutellum. Dorsellum with strong sculpture, with median carina. Propodeum with a 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 five 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; Gt 2-3 with a very narrow shiny median stripe; tergites with very strong reticulation.
