Diagnosis (female). Antennal clava with a distinct constriction between C1 and C2 (Fig. 1027); genal carina present; mesoscutellum (Fig. 148) with complete submedian grooves, reticulate with slightly elongate meshes; hind coxa with a carina along posterior margin; gaster (Fig. 148) 2.8× as long as wide, medio-basal Gt 1 with a ±rectangular incision, with weak reticulation and more shiny than remaining tergites.

Female holotype: length of body 2.7mm.

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

Antenna with a distinct constriction between C1 and C2. Frons with strong reticulation, below eyes with weak reticulation and more shiny, clypeal area smooth; with a weak genal carina. Vertex outside ocellar triangle with strong reticulation, inside triangle with wrinkled sculpture.

Mesoscutum with strong reticulation, meshes predominantly isodiametric but with elongate meshes in posterior one-third of midlobe; midlobe without median groove, with nine scattered adnotaular setae. Mesoscutellum with strong reticulation, median median part with weaker reticulation and more shiny than lateral parts, meshes elongate, submedian grooves ±distinct and diverging towards posterior part. Dorsellum with strong reticulation. Propodeum with median carina triangular, narrow anterior part very short; callus with three setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa with a strong carina along posterior margin. Fore wing with 3–4 setae on dorsal surface of submarginal vein; speculum open below; costal setal row unbroken.

Petiole transverse and smooth. Gaster elongate; medio-basal Gt 1 with a ±rectangular incision, with very weak reticulation and shiny, remaning tergites with strong reticulation and dull.
