Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 (Fig. 717); genal carina absent; mesoscutellum (Fig. 172) with elongate meshes; hind coxa with a carina along posterior margin; gaster (Fig. 172) laterally flattened, 4.4× as long as wide, with very short Gt 2, 0.06× as long as Gt 4, Gt 1 with weak reticulation and shiny, Gt 1-4 with a smooth median line, Gt 7 with apical half dark yellowish-brown.
Female holotype: length of body 3.5mm (paratype 3.6mm).
Scape with basal half yellowish-brown and apical half brown, pedicel and flagellum dark brown. Face below level of toruli golden-green but with median part metallic bluish-green, clypeus brown, frons metallic bluish-green, antennal scrobes black; vertex black with blue and green tinges. Mesoscutum golden-green with purple tinges in posterior part; mesoscutellum metallic bluish-green; propodeum golden-green. Legs with fore coxa golden-green, mid coxa dark brown, hind coxa metallic bluish-green; trochanters yellowish-brown; femora dark brown with apex yellowish-brown; tibiae yellowish-brown; T1–3 yellowish-brown, T4 brown. Petiole black. Gaster metallic bluish-green with some parts golden-green, Gt 7 with apical half dark yellowish-brown; gonoplac black.
Antenna with a weak constriction between C1 and C2. Face below level of toruli and scrobes with weak reticulation, clypeus smooth, frons with strong reticulation; genal carina absent. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with an indistinct median groove in posterior two-thirds, with 12 scattered adnotaular setae. Mesoscutellum with strong reticulation, meshes elongate; submedian grooves ±distinct, straight and diverging towards posterior part. Dorsellum with strong reticulation. Propodeum with a wide median carina that expands in posterior part, posterior part concave; callus with two setae.
