Diagnosis (female). Antenna with distinct constriction between C1 and C2 ( Fig. 849 ); genal carina present; mesoscutellum ( Fig. 550 ) with submedian grooves with outer margin absent, diverging towards both anterior and posterior parts, median part with very weak reticulation and shiny, lateral parts rugose; dorsellum with median carina; propodeum ( Fig. 550 ) with strong irregular carinae and weak reticulation, callus with eight setae; petiole transverse with strong sculpture on dorsal part; gaster ( Fig. 550 ) 2.0× as long as wide, medio-basal Gt1 with longitudinal carinae laterally, tergites with strong reticulation.

Scape black with ventro-basal half yellowish-brown, pedicel and flagellum black. Head with frons golden-green, antennal scrobes golden and clypeus black; vertex metallic greenish-blue. Mesosoma golden with red tinges. Legs with fore and hind coxae golden-green, mid coxa dark brown; trochanters, femora, tibiae and tarsi yellowish-brown. Petiole black. Gaster with Gt1 golden with posterior margin metallic purple, Gt2-7 metallic purple; 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.

Mesoscutum with strong reticulation and isodiametric meshes on sidelobes, midlobe with strong reticulation and elongate meshes on median part, rugose on parts close to notauli, with a complete median groove; midlobe with 18 setae on rugose parts. Mesoscutellum with submedian grooves with outer margin absent, diverging towards both anterior and posterior parts, median part with very weak reticulation and shiny, lateral parts rugose with 20 scattered setae. Dorsellum with weak reticulation, with median carina. Propodeum with a wide median carina that expands in posterior part; with strong irregular carinae and weak reticulation; callus with eight setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with eight setae on dorsal surface of submarginal vein; speculum open below.

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