( Figs 268, 269 View Figs 268–271 , 747 View Figs 742–750 )

Diagnosis (female). Antennal clava with a weak constriction between C1 and C2 ( Fig. 747 View Figs 742–750 ); mesoscutum ( Fig. 268 View Figs 268–271 ) with strong reticulation, meshes elongate, and with a weak median groove in posterior one-third; mesoscutellum ( Fig. 268 View Figs 268–271 ) with submedian grooves distinct, curved and diverging towards posterior part, with a ±complete median groove; dorsellum with median carina; propodeum ( Fig. 268 View Figs 268–271 ) with strong irregular carinae medially, callus with four setae; petiole very short, just a narrow band; gaster ( Fig. 268 View Figs 268–271 ) 2.6× as long as wide, medio-basal Gt 1 with short longitudinal carinae laterally, tergites with strong reticulation.

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

Mesoscutum with strong reticulation, meshes isodiametric on sidelobes, elongate on midlobe; midlobe with a median groove in posterior one-third, with nine scattered adnotaular setae. Mesoscutellum with strong reticulation on median part and with a weak but ±complete median groove, lateral parts with strong reticulation, meshes elongate; submedian grooves distinct, curved and diverging towards posterior part; with four setae scattered over lateral parts. Dorsellum with weak reticulation, with median carina. Propodeum with a few strong irregular carinae on median part, laterally with strong reticulation; callus with four setae. Fore and hind coxae with strong reticulation, mid coxa with weak reticulation. Fore wing with five setae on dorsal surface of submarginal vein; speculum closed; costal setal row unbroken.
