Petiole black. Gaster with Gt1 golden-red, Gt2-5 metallic purple medially and golden laterally, Gt6-7 black with golden tinges; gonoplac black.

Antenna with distinct constriction between C1 and C2. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with weak reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior ocelli in posterior part. Occipital margin carinate.

Mesoscutum with strong reticulation and isodiametric meshes, midlobe with parts close to notauli rugose, with median groove indicated but very weak; midlobe with 16 setae scattered over rugose parts. Mesoscutellum with median part with very weak reticulation and shiny, lateral parts rugose with four scattered setae; with outer margin of submedian grooves absent, grooves curved and diverging slightly towards posterior part. Dorsellum with strong reticulation, with median carina. Propodeum with a strong median carina that expands anteriorly and posteriorly; with strong irregular carinae mixed with strong reticulation; callus with two 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 open below; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster elongate; medio-basal Gt1 with longitudinal short carinae; tergites with rather weak reticulation.
