Diagnosis. Female. Fore wing length 7.6 mm (8.0mm in Richards 1978). Humeral lobes small and rather round; first metasomal segment short for this species-group (Figs 10, 11), length less than [mesoscutum + scutellum + metanotum], spiracles not prominent; overall color yellow, mesopleuron with strong dark brown to blackish mark near posterior margin and scrobe, and a large diffuse light brown mark anteriorly; hind trochanter and most of hind femur and tibia, and hind tarsus entirely black to dark brown; most of metasomal terga light testaceous with narrow yellow marginal bands.
Redescription. Female. Wing length 7.6 mm (8.0mm in Richards 1978). Head as high as wide in frontal view (Fig. 16), FHH/IntOW 1.05; clypeus about as high as wide, H/WCLP 1.04; apex narrowly truncate; malar space very narrow; tentorial pit much closer to eye than to antennal socket; antennal scape moderately elongated, L / Wesc 2.8; posterior occeli widely separated; POL more than two diameters; POL/OOL 1.63; occipital carina well developed, distinct in lateral view and ending below the level of ocular sinus; gena considerably narrower than upper lobe of the eye; pronotum without a lateral fovea; anterior margin of pronotum with lamella raised and reflexed, in profile as a lip turned backwards in more than 180 degrees; region immediately behind the lamella without secondary margin; humeral angle well developed WCAR/WMS 1.14; pronotal carina high, forming comparatively smaller round humeral lobes, middle section distinctly straight (Fig. 11); mesoscutum about as long as wide L/WMS 1.0; hind tarsi with asymmetric claws, inner claw longer, with apex uniformly rounded, but not enlarged or spoon-shaped; propodeum with median furrow shallow, developed on more than 4/5 of the length of propodeal dorsum, propodeal valve expanded below in lateral view, with triangular outline; first metasomal segment short, regularly widening from base to apex (Figs 10, 11), which is ca. 1.72 × wider than base; LSI/HMP 1.13; spiracles not prominent.
