Diagnosis (female). Antenna with distinct constriction between C1 and C2 ( Fig. 857 ); genal carina present; mesoscutellum ( Fig. 558 ) with strong reticulation on lateral parts, with weak reticulation on median part, meshes strongly elongate and surface thus appearing striate, submedian grooves strong and parallel; dorsellum without median carina; propodeum ( Fig. 558 ) with strong reticulation and irregular carinae, callus with seven setae; petiole transverse, dorsal part with strong sculpture; gaster ( Fig. 558 ) 1.7× as long as wide, tergites with strong reticulation, medio-basal Gt1 with longitudinal short carinae, apex of gonoplac blunt ( Fig. 559 ); body black without metallic tinges ( Figs 558, 559 ).

Female holotype: length of body 2.2mm (paratypes 1.6–1.9mm). Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head and mesosoma black without metallic tinges. Legs with fore and hind coxae black, mid coxa brown; trochanters, femora, tibiae and tarsi yellowish-brown. Petiole and gaster black.

Antenna with a strong constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, antennal scrobes with weak reticulation; with genal carina. Vertex with strong reticulation outside ocellar triangle, with irregular carinae inside triangle, with a carina between posterior part of posterior ocelli. Occipital margin with a carina behind ocellar triangle.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with median groove indicated but weak, with 14 scattered adnotaular setae. Mesoscutellum with strong reticulation on lateral parts, with weak reticulation on median part, meshes strongly elongate; submedian grooves strong and parallel; with nine setae scattered over lateral parts. Dorsellum with strong sculpture, without median carina. Propodeum with a strong wide median carina that expands both anteriorly and posteriorly; with strong reticulation and strong irregular carinae; callus with seven setae. Fore and hind coxae with strong reticulation, mid coxa with very weak reticulation. Fore wing with 5&6 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

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