Head with frons golden-green, clypeus dark brown, antennal scrobes black; vertex metallic bluish-green. Mesoscutum, mesoscutellum and propodeum golden-green. Legs with fore and mid coxae black with metallic tinges, hind coxa golden-green; trochanters dark brown; femora golden-green with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster with Gt 1 metallic bluish-green with posterior margin golden-purple, Gt 2-5 golden-purple, Gt 6-7 golden-green; gonoplac black.

Antenna with solid clava. 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 reticulation.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, ±elongate on midlobe; midlobe without median groove, with six scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes isodiametric, without median groove, submedian grooves weak but traceable in posterior half, running close to and parallel with lateral margin of mesoscutellum; anterior pair of setae situated in the middle of mesoscutellum. Dorsellum with strong reticulation. Propodeal callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a carina along posterior margin. Fore wing with three setae on dorsal surface of submarginal vein; speculum open below and towards base of wing; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a transverse edge dorsally, all tergites with strong reticulation.
