Diagnosis (female). Antenna with distinct constriction between C1 and C2 ( Fig. 796 ); genal carina present and strong; mesoscutellum ( Fig. 414 ) with very weak reticulation on median part, lateral parts with strong reticulation, meshes elongate, median groove indicated but indistinct, submedian grooves distinct in posterior half, indistinct in anterior half, straight and ±parallel, subdivided by transverse carinae; dorsellum without median carina; propodeum ( Fig. 414 ) with median part with strong irregular carinae and lateral parts with strong reticulation, callus with two setae; petiole transverse with strong sculpture on dorsal part; gaster ( Fig. 414 ) short ovate, 1.3× as long as wide, tergites with strong reticulation, gonoplac dark brown ( Fig. 415 ). Small (1.5mm), predominantly black to dark brown species ( Figs 414, 415 ).

Female holotype: length of body 1.5mm.

Scape yellowish-brown, pedicel and flagellum dark brown. Body dark brown to black with very weak metallic tinges; gonoplac dark brown. Legs with fore and mid coxae dark brown, hind coxa black with anterior part dark brown; trochanters and femora dark brown, tibiae and tarsi yellowish-white.

Antenna with a distinct constriction between C1 and C2. Frons with strong reticulation, clypeus smooth, scrobes with weak reticulation; with a strong genal carina reaching almost to level of lower margin of eyes. Vertex with wrinkled sculpture. Occipital margin carinate.

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe without a median groove, with eight scattered adnotaular setae. Mesoscutellum with very weak reticulation on median part, lateral parts with strong reticulation, meshes elongate; median groove indicated but indistinct; submedian grooves distinct in posterior half, indistinct in anterior half, straight and ±parallel, subdivided by transverse carinae; with five setae scattered over lateral parts. Dorsellum with strong reticulation, without median carina. Propodeum with a wide median carina that expands in anterior and posterior parts; median part with strong irregular carinae and lateral parts with strong reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with 3&4 setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.

Petiole transverse with strong sculpture on dorsal part. Gaster short ovate, almost circular; tergites with strong reticulation.
