Diagnosis (female). Antennal clava ±compact and distinctly wider than short funiculars, funiculars and clavomeres 1+2 yellowish-brown (Fig. 1017); genal carina present; mesoscutellum ( Fig. 112 ) with strong reticulation, meshes elongate, submedian grooves indistinct, running parallel with lateral margins of mesoscutellum and thus diverging towards posterior part; fore coxa with a sharp edge along posterior margin, hind coxa without carina along posterior margin; gaster ( Fig. 112 ) 1.8× as long as wide, Gt 2 0.4× as long as Gt 4; medio-basal Gt 1 with a weak ±semicircular incision.

Female holotype: length of body 1.5mm (paratypes 1.4–1.6mm).

Scape dark brown with apex yellowish-brown, pedicel dark brown, flagellum with funiculars and C1 and C2 yellowish-brown, C3 dark brown. Head golden-green, clypeus dark brown. Thoracic dorsum golden-green. Legs with coxae golden-green; fore and mid trochanters dark brown, hind trochanter yellowish-brown; fore and mid femora golden-green with apex yellowish-brown, hind femur completely golden-green; fore tibia yellowish-brown, mid and hind tibiae dark brown; T1–3 dark yellowish-brown, T4 brown. Petiole black. Gaster metallic greenish-blue; gonoplac black.

Antenna with solid clava. Frons and vertex with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with six setae in one row close to notauli. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves indistinct, running parallel with lateral margins of mesoscutellum and thus diverging towards posterior part; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with weak sculpture. Propodeum with triangular median carina, concave; callus with three setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation; fore coxa with a sharp edge along posterior margin, hind coxa without carina along posterior margin. Fore wing with 4–5 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster ovate-elongate; medio-basal Gt 1 with a weak ±semicircular incision, with weak reticulation and shiny, remaining tergites with strong reticulation.
