Supraclypeal area medially strigate, laterally and medially finely punctate, moderately pilose, medially with oval prominent area; between antennal foramens with three U-shaped, concentric carinae, medially interrupted; radicle foveolate. White band starting at flagellomere 8, reaching flagellomere 12; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with very faint but distinct median longitudinal carina, medially without longitudinal elevation, near antennal sockets striate; dorsal half medially rugulose. Vertex rugulose around ocelli, with very coarse punctures, without sulcus; gena and vertex behind ocelli minutely strigulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally uniformly arched, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 0.85 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.11 as long as wide; in lateral view, mesosoma middle width 0.18 mm. Pronotum centrally corrugated, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling finely rugulose; collar dorso-laterally rounded, distinctly swollen, anteriorly smooth; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe with longitudinal sulcus; notaulus moderately impressed, posteriorly abruptly curved, Ushaped. Scutoscutellar groove smooth, polished; scutellum 0.9 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.28 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 stout, dorsally curving backwards; dorsal end of epicnemial carina reaching 0.2 of posterior margin of pronotum, behind epicnemial carina with rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, deeply impressed; markedly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter V-shaped, expanded as two deltaic perpendicular projections. Transverse furrow at base of propodeum laterally 0.37 as long as anterior portion of propodeum deep and moderately narrow, medially wide, markedly corrugated; anterior margin of propodeum without teeth; propodeum 1.22 as long as wide medially; anterior portion of propodeum with sparse coarse punctures, medially with two posteriorly convergent longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum confused-rugose, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two stout parallel longitudinal carinae; anterior transverse carina of propodeum complete, stout, entirely slightly arched forwards; posterior transverse carina represented by apophysis, present laterally as carina; apophysis 0.83 as high as wide; propodeal spiracle 1.40 as long as wide; pleural carina of propodeum complete, moderately stout; lower division of metapleuron punctate, sparsely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs entirely slightly sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.75 as long as vein 2cu-a; vein 4Rs 0.80 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.78 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M indistinct. Hind wing: vein 1Cu 1.92 as long as vein cu-a; vein 2-1A reaching 0.83 of distance to posterior margin.

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

Metasoma. T1 0.56 as long as hind femur, without basolateral tooth; minutely coriarious; spiracle at anterior 0.60, prominent; postpetiole dorso-anteriorly flat; T2–8 minutely coriarious; almost glabrous; T2 1.17 as long as wide at apex; apex of T2 1.61 as wide as base.

Color. Head, mesosoma and metasoma black with bright yellow (232,217,141) marks. Head: yellow; mandible brownish; two longitudinal marks extending from anterior tentorial pit to base of clypeus, supra-antennal area medially, interocellar area, vertex centrally, and occiput, black; scape ventrally yellow; scape dorsally, pedicel and flagellum, brown; flagellum completely whitish at f9–12, partially at f8 and f13. Mesosoma : black except for the following yellow marks: collar laterally, pronotal swelling, longitudinal lanceolate mark at posterior 0.9 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, tegula, large mark extending from subalar ridge along epicnecium and mesopleuron to entire dorsal margin of sternaulus, except over rounded confused–rugulose area behind epicnemial carina, hypoepimeron, mesothoracic venter, both upper and lower division of metapleuron, hind margin of metanotum, and two lateral longitudinal marks at posterior portion of propodeum. Legs: mostly orange; fore and mid coxae yellow with dorsal black spot at apical 0.3; hind coxae yellow with two longitudinal black marks, ventral one at basal 0.6, dorsal one at entire length, anchor–shaped; all first trochanters, apical 0.2 of hind tibia, basal 0.5 of t1, and all t5, dark brown; tarsi whitish towards apex. Metasoma: black except for the following yellow marks: T1 basolaterally and at posterior 0.1, posterior 0.2 of T2–8, S1, and S2–8 laterally.

Comments. Similar to T. morelus sp. nov., from which it is differentiated by having central lobe of mesoscutum with longitudinal sulcus (vs. without sulcus or carina in T. morelus sp. nov.); mesopleuron with two black marks not connected, dorsally around hypoepimeron, and ventrally at confused-rugulose area just behind dorsal end of epicnemial carina (vs. with one black mark extending anteriorly around hypoepimeron and at confused-rugulose area; Fig. 103 View FIGURES 97–104. 97–98 ); sternaulus with a very narrow brown mark, centrally interrupted (vs. with complete and wide brown mark; Fig. 13 View FIGURES 12–15 ); pleural carina of propodeum complete, moderately stout, as in Fig. 41 View FIGURES 41–44. 41 (vs. irregular and faint, obsolescent posteriorly, fused with sculpture of propodeum and lower division of metapleuron); hind leg blackish at first trochanter, 0.2 apical of tibia, and 0.5 basal of t1 (vs. yellowish, except coxa and t5); hind wing vein 1Cu almost 2 as long as vein cu-a (vs. about 1.5 as long as vein cu-a); T1 without basolateral tooth, as in Fig. 54 View FIGURES 45–54. 45 (vs. with faint but distinct basolateral tooth).
