The length of antenna 0.8 times as long as the body; third segment (including annellus) 1.5–1.6 times longer than fourth segment, length of third and fourth segments 3.4–4.0 and 1.9–2.3 times their width, respectively (Fig. 1b); length of maxillary palp 1.9 times the height of head (Fig. 3b); eye in dorsal view 1.8–2.25 times as long as temple (Figs 1d, 3d); eye in lateral view 1.4–1.5 times higher than wide (Figs 1c, 3c); frons largely smooth; vertex and temple smooth; OOL:diameter of ocellus: POL = 5–8:2.3–5:3; face 1–1.3 times wider than high, rather convex medially and coarsely punctate; clypeus wide, near rectangle, smooth and finely rugose apical, distinctly separated from face in colouration (Figs 1b, 3b); malar space absent; mandible with 3 teeth, dorsal tooth enlarged, lobe-shaped (Figs 1c, 4f), ventral tooth medium-sized and lobe-shaped, middle tooth small and slightly acute, with minute incision between first and second teeth, medial length of mandible 0.9–1.2 times its maximum width.

Mesosoma. Length of mesosoma 1.5–1.6 times its height in lateral view (Figs 1e, 3e); medio-anteriorly pronotum inconspicuously crenulate, remainder of pronotum smooth (Figs 1f, 3f); epicnemial area rugose; precoxal sulcus crenulate and groove gradually deeper, not reaching middle coxa; pleural sulcus narrowly crenulated ventrally; episternal scrobe round and deep; metapleuron largely smooth medially, but slightly crenulated ventrally (Figs 1e, 3e); mesoscutum smooth with median oval depression situated a little above the posterior margin in the apical half; notauli present anterior one fourth, shallow; scutellum smooth, scutellar sulcus deep, with one longitudinal carina, sulcus 3.3 times wider than its maximum length (Figs 1f, 3f); surface of propodeum distinctly rugose at middle, with a medio-longitudinal carina present at basal 0.3–0.5 of propodeum, areola present posteriorly, but with coarsely rugose-reticulation (Fig. 4a).

Wings (Figs 2a, 4b). Pterostigma wide, 5.0–­5.1 times longer than its maximum width. Vein r issuing from middle of pterostigma. r:3-SR:SR1 = 4:16–19:28–39; 1-SR+M not or slightly sinuate; SR1 curved; r 0.6 times as long as width of pterostigma; 2-SR of fore-wing slightly antefurcal or distinctly antefurcal; 1-CU1:2-CU1 = 1: 6–6.5; 3-CU1 distinctly longer than CU1b; 2-SR:3-SR:r-m = 13–15:20–22:7; m-cu postfurcal, converging to 1-M posteriorly; first subdiscal cell 4.1–4.3 times as long as wide; M+CU1 largely unsclerotised.

Legs: Hind coxa rather smooth (Fig. 1e) or densely punctate (Fig. 4e), without ventro-basal tubercle, rather elongated, longer than fore and middle coxa. Hind femur distinctly widened, coarsely punctate and with long setae, with nine teeth (one large, three medium-sized, four small and one combined tooth with one medium tooth and one small tooth apically) laterally, seven medium teeth inner laterally (Figs 2c, 4e); hind basitarsus 0.34 times as long as hind tibia. Ratio of hind femur:hind tibia:hind tarsus:hind basitarsus = 1.22:1.61:1.19:0.50.

Metasoma: Metasoma elongated (Figs 2b, 4d); first tergite smooth, apical two fifths with irregular longitudinal carinae, remaining tergites smooth; first tergite widened from base to apex, apical width 2.1–2.4 times longer than its basal width (Figs 2b, 4d); dorsope large and distinct; total visible length of ovipositor sheath 0.9–1.2 mm and 0.8–1 times as long as hind femur (Figs 2b, 4c).

Colour. Blackish-brown (Figs 1a, 3a); mandible, posterior area of clypeus, palpi, pronotum, fore and middle legs, trochanter and trochantellus of hind legs, apical third areas of hind femur yellowish-brown; pterostigma and anterior part of veins brown, remainder of veins and wing membrane hyaline. Head black; eyes grey; whole clypeus (Fig. 1b) or only its posterior area (Fig. 3b) yellowish-brown; mandibles yellowish with dark brown margins, median tooth dark brown; palpi off white; ocelli transparent; antenna with scape and pedicel yellowish-brown and flagellum brown; mesoscutum yellowish-brown, except median depression and area around median depression brown or entirely brown (Figs 1f, 3f); scutellum and propodeum black; legs in general pale yellow to brown gradually with fore- and mid-leg coxae and trochanters yellowish-white, fore- and mid-femora and tibiae yellowish-brown, tarsi light brown, hind coxa light brown laterally to dark brown (Fig. 4e) and apical three fourths of hind femur black, basal one fourth yellowish-white and extreme basal margin brown; hind tibia gradually darker from apical one fifth pale brown to two fifths apically brown and remaining light brown, hind tarsus brown; wings hyaline with pterostigma dark brown; first tergite of metasoma black, following tergites reddish-brown dorsally and yellowish laterally; ovipositor brown.

Variation: Body length (including ovipositor) 3.8−4.5 mm; antennal segments of female 25−28; 1-SR+M 0.3−0.4 mm; hind femur distinctly widened with six to nine teeth (one large, three to four teeth medium, two to four teeth small and one combined by one medium tooth and one small tooth apically) laterally, 7 medium inner teeth laterally or 6 medium teeth and one combined tooth with one medium tooth and one small inner tooth apico-laterally; lateral length of first tergite 0.4−0.5 mm.
