Re-description.

Female; length of body 2.8 mm, of fore wing 3.0 mm.

Head. Antenna with 29 segments (Fig. 25; broken and lost); third segment 2.3 × longer than its width, 1.2 × longer than fourth segment; eye 1.5 × longer than temple in dorsal view (Fig. 23); vertex granulate and sparsely setose; frons and occiput shiny and granulate; face densely punctate and setose (Fig. 21); clypeus 2.5 × wider than its maximum height; clypeus densely setose, its ventral margin slightly protruding downward; hypoclypeal depression distinct; maxillary palpi nearly 0.7 × as long as height of head; malar sulcus absent; occipital carina completely present and crenulate, (Figs 29, 32); mandible gradually widened basally, moderately setose and hardly twisted in lateral view without acute basal lamella (Fig. 33).

Mesosoma. Mesosoma 1.3 × longer than its height (Fig. 29); pronope absent but transverse crenulated groove and sparsely setose along lateral margin (Fig. 30); pronotal side granulate with ventral crenulated groove; propleuron granulate (Fig. 29); mesopleuron largely coriaceous, but precoxal sulcus crenulate, wide, oblique and reaching anterior area (converging epicnemial area and dorsal crenulate carina); epicnemial area crenulate; mesopleural sulcus crenulate; mesosternum densely setose; anterior groove of metapleuron crenulate, remaining area reticulate-rugose, shiny and densely setose; notauli distinctly crenulate antero-medially, but gradually obsolescent posteriorly (Fig. 29); medio-posterior depression of mesoscutum large, elliptical and deep; mesoscutum coriaceous with few setae along the notaulic course; scutellar sulcus medium-sized, moderately crenulate and gradually narrowed laterally; scutellum granulate and rather flat in lateral view; propodeum entirely reticulate-rugose and densely setose with a short medio-longitudinal carina.

Wings. Fore wing (Fig. 27): Pterostigma triangular and gradually narrowed apically; vein r sublinear with vein 3 - SR; vein 1 - M nearly straight; vein 1 - SR + M straight; vein 2 - SR slightly sinuate and oblique; vein 3 - SR 1.5 × longer than vein 2 - SR; r: 3 - SR: SR 1 = 5: 18: 37; vein SR 1 straight; vein m-cu distinctly postfurcal; first subdiscal cell open; vein CU 1 b short and incomplete. Hind wing (Fig. 28): vein m-cu absent; vein 2 - M absent.

Legs. Length of hind femur 4.4 × its maximum width (Fig. 36).

Metasoma. First metasomal tergite 0.9 × as long as its apical width, its surface striate-rugose and slightly convex medio-basally in lateral view (Figs 26, 30); dorsope absent; second metasomal suture obsolescent (Fig. 30); second tergite shiny and granulate, with shallow pair of depressions medio-basally; third tergite granulate medially and following tergites shiny and smooth, with band of setae posteriorly; setose part of ovipositor sheath 0.5 × longer than first tergite (Fig. 34).

Colour. Body generally black (Fig. 26); head yellowish-brown but frons and vertex black medially (Fig. 32); legs and ovipositor, light brown; second and half of basal third tergites, brown; pterostigma and vein of wings, light brown; wings, subhyaline.
