Comparison. Differs from other species of the genus by the combination of brown metasoma, pale brown pterostigma ( Fig. 32 ), uniformly brown or black antenna ( Fig. 100 ) and ovipositor sheath 1.7–1.85× as long as hind tibia.

Description. Female. Body length 2.8 mm. Fore wing length 2.45 mm.

Head in dorsal view with gena about 0.8× as long as eye width. Flagellum with 15–16 flagellomeres ( Fig. 100 ); subbasal and mid flagellomeres 1.4–1.7×, and subapical flagellomeres 1.2× as long as broad. Clypeus lenticular, finely granulate, dull, with fine and sparse punctures. Malar space somewhat shorter than basal mandibular width.

Notaulus as small tubercle distant from anterolateral margin of mesoscutum. Propodeum of holotype covered by glue; in paratype transverse carina well developed, basal part as long as apical area, and apical area about 1.5× as long as maximally broad. Propodeal spiracle very small, separated from pleural carina by 2.0 (in holotype) or almost 4.0× (in paratype) diameter of spiracle.

Fore wing with vein R1 not reaching apex of the wing. Vein 2m-cu slightly postfurcal. Hind wing with vein cu1&cu-a slightly reclivous.

Second tergite as long as broad anteriorly. Ovipositor very weakly upcurved in basal 0.8 and somewhat stronger upcurved apically; sheath 1.7–1.85× as long as hind tibia.

Head, mesosoma and first metasomal tergite black; paratype with mesoscutum peripherally and on notaular lines, and mesopleuron in upper anterior quarter reddish brown. Clypeus yellow, brownish near its upper margin. Mandible (teeth blackish), palpi and tegula yellow. Antenna brown to black. Pterostigma pale brown. Legs brownish yellow, hind coxa blackish. Metasoma behind first tergite brown.
