Antenna with 19 segments (Fig. 24); between stemmaticum and eyes sparsely setose without depression; occipital carina entirely absent (Figs 19–21); clypeus 4.3 × longer than its maximum height (Fig. 19); mandible gradually widened basally; vein 1 - R 1 of fore wing 1.7 × longer than distance between apex of vein 1 - R 1 and apex of fore wing; vein cu-a of fore wing interstitial (Fig. 15); maxillary palpi 0.5 × as long as height of head; scutellar sulcus robust and distinctly crenulate medially (Fig. 17); fore femur somewhat wider than middle femur; strong dorsal carinae separated up to posterior of first metasomal tergite; first metasomal tergite entirely granulate-rugose (Figs 18, 23).
Re-description.
Female; length of body 1.6 mm, of fore wing 1.3–1.6 mm, male; length of body 1.3 mm, of fore wing 1.5 mm.
Head. Antenna with 19 segments, 1.1 × longer than body (Fig. 24); third segment 3.1 × longer than its width and 1.2 × longer than fourth segment (Figs 24, 25); middle flagellar segment 2.9 × longer than its width; depression of frons slightly present near antennal sockets; eye as long as temple (Fig. 20); vertex, frons, stemmaticum and occiput smooth and glabrous; face shiny, smooth and moderately setose (Fig. 19); median keel of frons slightly present; clypeus 4.3 × wider than its maximum height; clypeus narrow, trapezoid-shaped, shiny, smooth, moderately setose and flat in lateral view, and its ventral margin straight; hypoclypeal depression slightly present; maxillary palpi 0.5 × as long as height of head; malar sulcus present and short; occipital carina absent (Figs 20, 21); mandible slightly twisted, moderately setose and slightly widened basally.
Mesosoma. Mesosoma 1.3 × longer than its height (Fig. 16); pronope absent; pronotal side smooth, glabrous, and anterior and posterior groove of pronotal side smooth (Fig. 16); propleuron shiny, smooth and rather moderately setose; mesopleuron largely smooth, but precoxal sulcus deeply narrowly crenulate; epicnemial area narrowly crenulate ventrally, remaining area smooth; mesopleural sulcus smooth; mesosternum rather sparsely setose; anterior groove of metapleuron smooth; metapleuron largely shiny, smooth and densely setose posteriorly; notauli absent on disc of mesoscutum, but deeply crenulate anteriorly (Fig. 17); medio-posterior depression of mesoscutum absent; mesoscutum smooth and glabrous; scutellar sulcus straight, relatively short, medium-sized and densely crenulate medially, but reduced laterally; scutellum smooth, glabrous and not protruding above level of mesoscutum in lateral view (Figs 16, 17); propodeum smooth and glabrous without any carinae (Figs 18, 22).
Wings. Fore wing (Fig. 15): Pterostigma triangular; vein 1 - M slightly curved; vein 1 - SR + M curved downwards; vein 3 - SR + SR 1 strongly curved and pointing towards apex of vein 1 - R 1; vein 1 - R 1 of fore wing about 1.7 × longer than distance between its apex and apex of fore wing; vein 3 - SR converging with vein 2 - M; vein 1 - SR short; vein cu-a interstitial; first subdiscal cell open. Hind wing: entirely narrow and subparallel-sided; vein cu-a absent; vein m-cu absent; vein 2 - M pigmented basally and reduced apically.
Legs. Length of hind femur 3.9 × its maximum width; fore femur slightly wider than middle femur, nearly 1.1 × wider than maximum width of middle femur.
Metasoma. First metasomal tergite as long as its apical width, its surface reticulate-rugose with strong dorsal carinae, and slightly convex medially in lateral view (Fig. 14); dorsope absent; second metasomal suture obsolescent dorsally (Fig. 18); second tergite granulate and glabrous, with pair of triangular depressions basally; third tergite granulate antero-medially and remaining area smooth; following tergites shiny, smooth, and moderately setose posteriorly.
Colour. Body generally dark brown to black (Fig. 14); clypeus and mandible, light brown; pronotal side ventrally and first to third anteriorly metasomal tergites, brown; antenna and legs, dark brown (except legs darker brown dorsally); pterostigma and veins of wings, greyish-brown; wings, hyaline.
