Gaster with Gt 1 black with metallic blue tinges, remaining tergites black with metallic purple tinges; gonoplac black.

Antenna with a weak constriction between C1 and C2. Face below level of toruli with weak reticulation, clypeus smooth, frons with strong reticulation, antennal scrobes with weak reticulation; with genal carina. Vertex with strong transverse carinae; with a carina between posterior ocelli in posterior part.

Mesoscutum with strong reticulation, meshes isodiametric; midlobe with a complete median groove, with white setae scattered all over. Mesoscutellum with median median part with strong reticulation in anterior half and weak reticulation in posterior half, lateral parts with strong reticulation/rugosity; submedian grooves distinct, situated close to one another, ±straight and diverging towards posterior part; with 16 white setae scattered over lateral parts. Dorsellum with weak sculpture and shiny, with median carina. Propodeum a strong median carina that expands anteriorly and posteriorly; with strong irregular carinae; callus with seven setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed; costal setal row sparse but unbroken.

Petiole very short, just a narrow band. Gaster ovate; medio-basal Gt 1 with longitudinal carinae laterally; tergites with strong reticulation.
