( Figs 598, 599 , 870 )

Diagnosis (female). Antenna with constriction between all clavomeres, especially distinct between C1 and C2 ( Fig. 870 ); genal carina present; mesoscutellum ( Fig. 598 ) completely rugose without submedian grooves but with a narrow raised stripe medially, lateral parts with setae all over; dorsellum without median carina; propodeum ( Fig. 598 ) with strong reticulation and irregular carinae, callus with five setae; gaster ( Fig. 598 ) 2.3× as long as wide, medio-basal Gt1 with several longitudinal short carinae, tergites with strong reticulation.

Female holotype: length of body 2.5mm.

Scape yellowish-brown with apical one-fifth infuscate, pedicel and flagellum dark brown. Face below level of toruli golden-green with clypeus dark brown, above toruli metallic blue, antennal scrobes black with metallic tinges; vertex metallic blue. Mesoscutum and mesoscutellum golden-green with blue tinges; propodeum golden-green. Legs with fore and hind coxae black with metallic blue tinges, mid coxa dark brown; trochanters yellowish-brown; femora yellowish-brown with base infuscate; tibiae and tarsi yellowish-brown, T4 brown. Petiole black. Gaster with Gt1-6 metallic greenish-blue, Gt7 black; gonoplac black.

Antenna with a strong constriction between C1 and C2 and weak constriction between C2 and C3. Face below level of toruli with strong reticulation, clypeus smooth, frons rugose, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with wrinkled sculpture inside ocellar triangle; with a carina between posterior part of posterior ocelli.

Mesoscutum with very strong reticulation, meshes isodiametric on sidelobes, slightly elongate to isodiametric on midlobe; with 26 scattered adnotaular setae. Mesoscutellum rugose; submedian grooves absent; with setae scattered over entire part except a bare median narrow stripe. Dorsellum with strong sculpture, without median carina. Propodeum with a strong and wide median carina that expands both anteriorly and posteriorly; with strong reticulation and strong irregular carinae; callus with five setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with six setae on dorsal surface of submarginal vein; speculum closed; costal setal row broken.

Petiole transverse, dorsal part with strong sculpture. Gaster elongate; medio-basal Gt 1 with several longitudinal short carinae; tergites with strong reticulation.
