Diagnosis (female). Antenna with a weak constriction between C1 and C2 (Fig. 1043); with genal carina; mesoscutum and mesoscutellum (Fig. 202) with strong reticulation with ±isodiametric meshes; propodeum (Fig. 202) with median carina strong and raised in a tooth in anterior part; hind coxa with a strong carina along posterior margin; gaster (Fig. 202) elongate, 3.1× as long as wide, Gt 2 0.2× as long as wide, and Gt 4 0.67× as long as wide, medio-basal Gt 1 with a transverse edge dorsally, with same strong reticulation as remaining tergites, but smooth above attachment point of petiole; gonoplac yellowish-brown (Fig. 203).

Female holotype: length of body 2.6mm.

Scape yellowish-brown with apico-dorsal part brown, pedicel and flagellum dark brown. Head with frons metallic greenish-blue, antennal scrobes black with metallic tinges and clypeus brown; vertex black with metallic greenish-blue tinges. Mesosoma golden-green with blue tinges. Legs with fore and mid coxae dark brown, hind coxa black with metallic tinges; trochanters pale brown; femora dark brown with apex yellowish-brown; tibiae and tarsi yellowish-white to yellowish-brown, T4 pale brown. Petiole black. Gaster with Gt 1 metallic greenish-blue with posterior margin dark brown, Gt 2-5 black with metallic purple tinges, Gt 6 metallic greenish-blue, Gt

7 black with metallic blue tinges; gonoplac yellowish-brown.

Antenna with a weak constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation.

Mesoscutum with very strong reticulation, meshes isodiametric on sidelobes, slightly elongate on midlobe; midlobe with median groove indicated, with seven setae in two rows close to notauli. Mesoscutellum with very strong reticulation, meshes isodiametric; submedian grooves absent; anterior pair of setae placed in the middle of mesoscutellum. Dorsellum with strong reticulation. Propodeum with median carina strong and raised in a tooth in anterior part; callus with two 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 four setae on dorsal surface of submarginal vein; speculum open below and towards base of wing; costal setal row unbroken.

Petiole very short, just a narrow band. Gaster elongate; medio-basal Gt 1 with a transverse edge dorsally, with same strong reticulation as remaining tergites, but smooth above attachment point of petiole.
