Supraclypeal area entirely strigulate, also densely punctate, moderately pilose, medially slightly prominent; between antennal foramens without V-shaped carina; radicle foveolate. Antenna with 24 flagellomeres; white band starting at flagellomere 8, reaching flagellomere 15; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with stout, median, arched, transverse carina, medially without longitudinal elevation, near antennal sockets striate; dorsal half medially rugulose. Paraocular area finely punctulate. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally absent, ventrally markedly projected as crest; hypostomal carina projected as crest; malar space 0.97 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.02 as long as wide; in lateral view, mesosoma middle width 0.15 mm. Pronotum centrally corrugated, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling smooth; collar dorso-laterally rounded, distinctly swollen, anteriorly smooth; epomia very faint, almost indistinct. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly convergent. Scutoscutellar groove markedly corrugated; scutellum 0.72 as long as wide; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.29 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat rounded; mesopleuron dorsally medially markedly strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina faint, dorsally curving forwards; dorsal end of epicnemial carina reaching 0.10 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed; faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter convex, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.20 as long as anterior portion of propodeum, moderately deep and narrow, medially wide, uniformly corrugated; propodeum 1.15 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum punctulate or with sparse coarse punctures, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum markedly strigate, striation medially arched backwards, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina absent, only with lateral slight swellings; propodeal spiracle 1.20 as long as wide; pleural carina of propodeum irregular and faint, obsolescent posteriorly, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron strigulate, sparsely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs entirely slightly sinuous; vein 1cu-a straight, arising near vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.48 as long as vein 2cu- a; vein 4Rs 0.94 as long as vein 4M, straight; cell 1+2Rs 0.60 as high as pterostigma, almost indistinct; vein 2M indistinct; vein 3M distinct. Hind wing: vein 1Cu 1.70 as long as vein cu-a; vein 2-1A reaching 0.75 of distance to posterior margin.

Legs. Tibia with sparse short bristles; hind coxa elongate.

Metasoma. T1 0.50 as long as hind femur, without basolateral tooth; minutely coriarious; spiracle at anterior 0.53, prominent; postpetiole dorsally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; almost glabrous; T2 1.43 as long as wide at apex; apex of T2 1.63 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.

Color. Head, mesosoma and metasoma black and yellow (237,221,110). Head: yellow; mandible teeth, clypeal apex medially, M-shaped mark at ventral half of supraclypeal area, supra-antennal area medially, interocellar area, vertex centrally, and occiput, black; scape, pedicel, and flagellum, brown; f9–14 completely, and f8, f15–16 dorsally, white. Mesosoma : black, except for the following bright yellow marks: propleuron, collar laterally, pronotal swelling, rounded mark at posterior 0.3 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum laterally, upper division of metapleuron, dorsal 0.9 of lower division of metapleuron, hind margin of metanotum, large mark extending from subalar ridge to posterior 0.6 of dorsal margin of sternaulus except around hypoepimeron and just behind epicnemial carina, hypoepimeron, mesothoracic venter, and two lateral longitudinal marks at posterior portion of propodeum. Legs: orange, yellowish posteriorly; fore, mid, and hind coxae dorsally with brown mark at apical 0.1, 0.3 and 0.7, respectively; hind coxa ventrally and dorsally, fore and mid first trochanters basally, both hind first and second trochanters, mid femur posteriorly and ventrally at apical 0.6, hind femur anteriorly and posteriorly, hind tibia except dorsally at basal 0.2, t1 at basal 0.1, and all t5, brown; hind first trochanter, and femur at basal 0.1, dark orange. Metasoma: black and yellow; T1–7 black with posterior 0.2 bright yellow; T8, S1, and S8 brown; S2–4 bright yellow, laterally brown; S5–6 brown, posteriorly bright yellow.
