Diagnosis. Female with head and antennal flagellum dark brown to black, mesosoma yellowish-brown, gaster brown ( Figs 15, 16 View FIGURES 13–16 ), male with head and mesosoma dark brown to black ( Figs 21, 22 View FIGURES 21–24 ); fore wing infumate with part below stigmal vein slightly darker ( Fig. 15 View FIGURES 13–16 ); pronotal collar without a carina along anterior margin ( Fig. 16 View FIGURES 13–16 ); midlobe of mesoscutum with four pairs of setae ( Fig. 16 View FIGURES 13–16 ); mesoscutellum with sublateral grooves slightly sinuate in lateral part, not joining in posterior part ( Figs 16 View FIGURES 13–16 , 22 View FIGURES 21–24 ); fore wing with 25+ scattered setae on ventral surface of costal cell, and with 15 setae along apico-dorsal margin ( Fig. 15 View FIGURES 13–16 ).

Description (female holotype). Length 2.9mm. Frons and vertex with weak reticulation, antennal scrobes smooth. Pronotal collar without a carina along anterior margin. Mesoscutum with weak reticulation; midlobe with four pairs of setae, three pairs are long and strong and one pair is short and weak. Mesoscutellum, axillae, dorsellum and propodeum smooth, without reticulation; mesoscutellum with sublateral grooves not joining in posterior part; propodeal callus with nine setae. Fore wing with nine setae on dorsal surface of submarginal vein; with 17 admarginal setae; costal cell with 25+ scattered setae on ventral surface, apico-dorsal margin with 15 setae. Gaster elongate.

Colour. Head dark brown to black. Antennae with scape yellowish-brown, pedicel pale brown, and flagellum dark brown. Mesoscutum, mesoscutellum, dorsellum and propodeum yellowish-brown. Fore leg with coxa and trochanter white, femur pale brown, tibia and tarsus yellowish-brown; mid and hind legs yellowish-brown. Wings infumate, fore wing with part below stigmal vein slightly darker. Petiole yellowish-brown. Gaster with Gt 1 pale brown, remaining tergites dark brown.
