Mesosoma. Slightly convex in profile (Figure 2g), pronotum, mesonotum and scutellum bearing short, thin suberect setae; pronotum entirely punctured, posterior margin markedly convex, without any median depression (Figure 2f); lateral panel with irregular rugae, followed by transverse striae ventrally; mesonotum cristate-punctured, transverse crests slightly raised in profile (Figure 2g); notauli shallowly impressed (Figure 2f); tegula finely imbricate, bearing short patch of setae baso-ventrally; mesoscutellum slightly convex in lateral view (Figure 2g), dorsal outline straight, markedly emarginate apically, with large fovea; postscutellum shiny with longitudinal areola; propodeum declining steeply onto metasoma, with posterolateral limit forming a right angle, with large irregular areola, carinate margin, median areola prominent and followed by nucha; propodeal spiracle slitlike; lateral costula setose; epicnemial carina faintly indicated (Figure 2g); ventral shelf virtually punctate as mesopleuron; adscrobal area of mesepisternum, entire mesepimeron and metepimeron with coarse setigerous punctures, setae short and suberect as on thoracic notum, interstices imbricate; femoral scrobe of mesopleuron strigose, margins well raised (Figure 2g).

Legs. Procoxa deeply depressed on front side, depression margined posterodorsally by raised carina forming a short flange (Figure 2g); protibia with apicodorsal short spine; mesotibia without any dorsal pegs, stout spine apico-ventrally; hind leg bearing sparse, thin and suberect setae more concentrated on ventral side of coxa, outer disc of femur and dorsal side of tibia; metafemur on outer disc with piliferous setigerous points without engraved network; its ventral margin with a row of 11 regularly distributed equal teeth, basal tooth not prominent, without any inner basal tooth; all tarsi thin, bearing slender normal claws without modification (Figure 3a).

Metasoma. Short petiole visible dorsally, dorsal surface with medio-longitudinal depression (Figure 3c); metasoma shorter than mesosoma, sub-acuminate apically; Gt1 as long as 0.54× entire length of metasoma, 1.1× as wide as long, smooth on dorsal disc with very fine microsculpture (visible only in certain angle of light), laterally with scattered pits and raised spiracle; Gt2–Gt5 finely microsculptured, dorsally with one row of setigerous micropits, laterally with setigerous punctures on anterior margin, posteriorly very finely microsculptured (Figure 3c); Gt6 densely punctured, with 5–6 rows of setigerous punctures, interspaces matt; spiracle conspicuous, peritreme raised; syntergum very short, spiracle conspicuous, medially carinate; sterna as sculptured as terga; ovipositor sheath barely visible dorsally (Figure 3d).

Male

Unknown.

Etymology
