Diagnosis (female). Antennal clava solid and flagellum short, pedicel+flagellum 0.7× as long as width of mesoscutum ( Fig. 705 ); with a short and weak genal carina close to mouth opening; mesoscutellum ( Fig. 90 ) with distinct submedian grooves that diverge slightly towards posterior part, median part with weak reticulation and with a weak median groove in anterior half; hind coxa without carina along posterior margin; gaster ( Fig. 90 ) 2.2× as long as wide, medio-basal Gt 1 with a very strong sharp transverse carina dorsally. Male recognizeable through the very strong and sharp transverse carina on medio-basal Gt 1 as in female.

Female holotype: length of body 2.6mm (paratypes 2.3–2.4mm).

Scape yellowish-brown with dorsal edge dark brown, pedicel and flagellum dark brown. Head with frons and vertex black with metallic greenish-blue tinges, antennal scrobes black, clypeus dark brown. Thoracic dorsum dull golden-green. Legs with fore and hind coxae golden-green, mid coxa black; trochanters dark brown; fore and mid femora dark brown with apex yellowish-brown, hind femur black with metallic tinges and apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown to yellowish-white, T4 brown. Petiole black. Gaster with Gt 1 dull golden-green in anterior half, posterior half and Gt 2-5 metallic dull purple, Gt 6 dull golden-green, Gt 7 black; gonoplac black.

Antenna with solid clava. Face below level of toruli laterally with weak transverse sculpture and medially smooth, just below toruli with long ovate pits with relatively strong reticulation, frons with strong reticulation, antennal scrobes with weak reticulation; with a short and weak genal carina close to mouth opening. Vertex with strong reticulation.

Mesoscutum with strong reticulation; midlobe with a ±complete median groove, close to notauli with ten setae in two rows. Mesoscutellum with distinct submedian grooves that diverge slightly towards posterior part, part, median part with weak reticulation and with a weak median groove in anterior half; lateral parts with relatively strong reticulation; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with strong reticulation. Propodeum with a strong median carina, with strong reticulation; callus with eight setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation; hind coxa without a carina along posterior margin. Fore wing with four setae on dorsal surface of submarginal vein; speculum partly open below; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a sharp transverse carina dorsally; Gt 1–6 with relatively weak reticulation and shiny, Gt 7 smooth.
