Diagnosis (female). Antenna with a constriction between C1 and C2 and between C2 and C3 (Fig. 800); with genal carina; clypeus strongly protruding (Fig. 893); mesoscutellum (Fig. 412) with very weak reticulation on median part and without median groove, lateral parts with strong reticulation, meshes elongate, submedian grooves curved with outer margin absent; fore and mid coxae yellowish-brown (Fig. 413); dorsellum with median carina; propodeum (Fig. 412) with strong irregular carinae and weak reticulation, callus with seven setae; petiole transverse with strong sculpture on dorsal surface; gaster (Fig. 412) 4.4× as long as wide, medio-basal Gt 1 with longitudinal carinae laterally, tergites with weak reticulation. Male flagellomeres with scattered setae (Fig. 974).
Female holotype: length of body 4.3mm (paratypes 4.2–5.2mm).
Scape yellowish-brown, pedicel dark brown in dorsal half, pale brown in ventral half, flagellum dark brown. Head with frons metallic bluish-green, antennal scrobes black, clypeus yellowish-brown; vertex metallic purple. Mesosoma golden-green. Legs yellowish-brown, hind coxa with basal half dark brown. Petiole black. Gaster with Gt 1 metallic bluish-green with posterior one-third dark brown with golden tinges, Gt2-5 dark brown with golden tinges, Gt6-7 black.
Antenna with a constriction between clavomeres. Frons with strong reticulation, antennal scrobes with weak reticulation; clypeus strongly protruding and smooth; with a strong genal carina that almost reaches up to level with lower margin of eye. Vertex with weak reticulation outside ocellar triangle, inside triangle with wrinkled sculpture.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes and elongate on midlobe, lateral part of midlobe rugose; midlobe with 18 scattered setae on rugose parts, with a median groove in posterior two-thirds. Mesoscutellum with very weak reticulation on median part and without median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves curved with outer margin missing; with 16 setae scattered over lateral parts. Dorsellum with strong reticulation, with median carina. Propodeum with strong irregular carinae and weak reticulation; callus with seven setae. Fore and mid coxae with weak reticulation, hind coxa with strong reticulation. Fore wing with 7&9 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
Petiole transverse with strong sculpture. Gaster very elongate; medio-basal Gt 1 with longitudinal carinae laterally; tergites with weak reticulation.
