Description. Holotype FEMALE. Fore wing length 7.10 mm.

Head. Mandible 1.53 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.60 as wide as high, subtriangular, finely punctate; apex 2.03 as long as base, truncate; apical margin sharp, medially straight. Supraclypeal area entirely strigate, with scarce punctures, densely pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with Vshaped carina; radicle punctate. Antenna with 23 flagellomeres; white band starting at flagellomere 8, reaching flagellomere 9; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supraantennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially scarcely punctulate, or strigulate. Paraocular area finely punctulate. Vertex punctate around ocelli, without sulcus; gena and vertex behind ocelli minutely strigulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 1.13 as long as basal width of mandible.

Mesosoma   . Mesosoma   in dorsal view 2.09 as long as wide; in lateral view, mesosoma middle width 0.20 mm. Pronotum centrally smooth, latero-ventrally rugulose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling finely rugulose; collar dorso-laterally rounded, distinctly swollen, anteriorly punctulate; epomia absent. Mesoscutum sparsely pilose, densely punctulate, covered with sparse coarse punctures, impression of notaulus corrugated, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly convergent. Scutoscutellar groove smooth, polished; scutellum 1.16 as long as wide, densely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.36 as long as wide; hind margin of metanotum with two lateral teeth. Subalar ridge somewhat elongate; mesopleuron dorsally strigate, include over hypoepimeron, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally curving forwards; dorsal end of epicnemial carina reaching 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed; markedly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter convex, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.28 as long as anterior portion of propodeum deep and wide, very markedly corrugated; propodeum 1.23 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigate, medially with two posteriorly convergent longitudinal carinae; lateral longitudinal carina of propodeum represented by faint but distinct subcircular carina; posterior portion of propodeum confused-rugose, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina represented by pair of high spine-like apophysis, posteriorly curved; apophysis 1.28 as high as wide; propodeal spiracle 1.36 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron strigate, densely pilose, juxtacoxal carina long and stout.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus present, almost indistinct; vein 1M+Rs posteriorly faintly sinuous; vein 1cu-a posteriorly slightly curved, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.77 as long as vein 2cu-a; vein 4Rs 0.87 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.73 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.67 as long as vein 2M. Hind wing: vein 1Cu 1.00 as long as vein cu-a; vein 2-1A reaching 0.90 of distance to posterior margin.

Legs. Tibia with dense short bristles; hind coxa globose.

Metasoma. T1 0.5 as long as hind femur, with faint basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.57, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 1.17 as long as wide at apex; apex of T2 1.82 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch absent.

Color. Head and mesosoma orange (216,091,024), metasoma pale yellow and dark brown (073,052,039). Head: orange; mandible teeth dark brown; clypeus and faint orbital band, yellowish; f8 and f9 ventrally partially white. Mesosoma   : orange. Legs: mostly orange; all t5 black; hind femur, hind tibia, and basal 0.9 of t1, dark brown; apical 0.1 of t1 and t2–4, white. Metasoma: orange, brown and pale yellow; T1 brown, anterior and posterior 0.1 pale yellow; T2–8 brown with posterior 0.4 pale yellow; S1 brown; S2–8 pale yellow, laterally black.

Comments. Readily differentiated from other species of the genus by the mostly orange head and mesosoma, except for clypeus and faint orbital band, yellowish ( Fig. 39 View FIGURES 36–39 ). The color pattern of mesoscutum, without yellow marks, resembles T. melgassus   sp. nov., and T. napus   sp. nov., from which it is differentiated by having supraantennal area completely orange (vs. medially black in T. melgassus   sp. nov. and T. heredius   sp. nov.); collar dorsolaterally rounded, distinctly swollen, as in Fig. 47 View FIGURES 45–54. 45 (vs. carinated, not swollen, as in Fig. 46 View FIGURES 45–54. 45 ); juxtacoxal carina long (vs. short).
