Diagnosis (female). Antenna with distinct constriction between C1 and C2 (Fig. 803); genal carina present; mesoscutellum (Fig. 426) with submedian grooves straight and ±parallel, median part with very weak reticulation; dorsellum with median carina; propodeum (Fig. 426) with strong carinae and strong reticulation, callus with two setae; fore coxa pale brown, mid coxa yellow, hind coxa yellow at apex and along anterior part, dark brown along posterior part (Fig. 427); petiole transverse with strong sculpture on dorsal part; gaster (Fig. 426) ovate, 1.5× as long as wide, tergites with strong reticulation, gonoplac short with tip pointed (Fig. 427). Small (1.5mm), predominantly dark brown species (Figs 426, 427).
Female holotype: length of body 1.5mm.
Scape yellowish-brown, pedicel pale brown, flagellum dark brown. Head dark brown with metallic tinges. Mesoscutum and propodeum dark brown; mesoscutellum dark brown with metallic bluish tinges. Legs with fore coxa pale brown, mid coxa yellow, hind coxa yellow at apex and along anterior part, dark brown along posterior part; trochanters, femora, tibiae and tarsi yellow. Petiole black. Gaster dark brown.
Antenna with a distinct 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 wrinkled sculpture inside ocellar triangle. Occipital margin carinate.
Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove, with six adnotaular setae in one row. Mesoscutellum with weak reticulation, especially so on median part, meshes elongate; submedian grooves distinct, straight and ±parallel; with three setae scattered over lateral parts. Dorsellum with weak sculpture, with median carina. Propodeum with a wide median carina that expands in posterior part; with strong irregular carinae and strong reticulation; callus with two setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with four setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
Petiole transverse with strong sculpture on dorsal part. Gaster ovate; tergites with strong reticulation; gonoplac short with tip pointed.
