Supraclypeal area entirely densely punctate, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens without V-shaped carina; radicle foveolate. Antenna with 29 flagellomeres; white band starting at flagellomere 7, reaching flagellomere 13; flagellum slender; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially punctulate, or rugulose. Paraocular area finely punctulate. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli punctulate, 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 1.06 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 1.70 as long as wide; in lateral view, mesosoma middle width 0.21 mm. Pronotum centrally smooth, latero-ventrally markedly strigate behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling strigulate; collar dorso-laterally carinated, not swollen, anteriorly punctulate; epomia very faint, almost indistinct. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe with faint longitudinal carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 0.83 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.45 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 straight; dorsal end of epicnemial carina not reaching ventral margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed, faint from anterior 0.5 to 0.8, faintly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter punctate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.65 as long as anterior portion of propodeum, moderately deep and very wide, markedly corrugated; anterior margin of propodeum without teeth; propodeum 0.96 as long as wide medially; anterior portion of propodeum with sparse coarse punctures, medially with two posteriorly convergent faint longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum confused-rugose, medially with distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina represented by crests, present laterally as carina; propodeal spiracle 1.82 as long as wide; pleural carina of propodeum present only posteriorly; lower division of metapleuron strigate, densely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs entirely sinuous; vein 1cu-a posteriorly markedly curved, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.62 as long as vein 2cu-a; vein 4Rs 0.86 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.89 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 1.43 as long as vein 2M. Hind wing: vein 1Cu 1.88 as long as vein cu-a; vein 2-1A reaching 0.76 of distance to posterior margin.

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

Metasoma. T1 0.53 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 1.01 as long as wide at apex; apex of T2 1.51 as wide as base.

Color. Head and mesosoma black and yellow, metasoma dark orange. Head: light yellow (239,223,151); mouthparts, mandible, apical margin of clypeus, supra–antennal medially, vertex and occiput, blackish; scape anteriorly bright yellow, dorsally black; pedicel and flagellomeres black, brownish towards apex; f9–11 entirely white, f8 and f12 mostly white. Mesosoma : black, except for the following bright yellow marks: propleuron ventrally, collar and pronotal swelling, longitudinal lanceolate mark at posterior 0.4 of central lobe of mesoscutum, axillary carina, scutellum, tegula, mesothoracic venter, upper division of metapleuron, and dorsal half of lower division of metapleuron, bright yellow; mesopleuron with three light yellow spots: from anterior margin of mesopleuron to posterior margin of sternaulus, at subalar ridge, and at hypoepimeron; large longitudinal brown (096,053,037) stripe covering sternaulus; ventral half of lower division of metapleuron anteriorly dark brown, posteriorly pale orange (206,124,058); posterior portion of propodeum black with two lateral longitudinal yellow marks. Legs: mostly orange (217,100,036); all t5 blackish, fore and mid t4 brownish; fore coxa yellow, posteriorly brown; trochanters yellowish towards apex. Metasoma: entirely dark orange.

Variation. Mandible ventrally yellow. Ventral yellow mark at mesopleuron medially narrow, black areas almost joining.

Comments. Similar to T. albimaculatus from which it can be distinguished by having clypeus and supraclypeal area entirely yellow (vs. clypeus apically and supraclypeal area ventrally, brown in T. albimaculatus ; Fig View FIGURES 55–69 . 68); posterior transverse carina of propodeum represented by crests, present laterally as carina (vs. crests absent, or carina not developed; Fig. 154 View FIGURES 151–156 ); posterior portion of propodeum medially with distinct and stout carina (vs. without distinct longitudinal carina); postscutellum black (vs. yellow; Fig. 154 View FIGURES 151–156 ); T1 entirely orange (vs. T1 orange with apical 0.1 yellow; Fig. 161 View FIGURES 157–162 ); sternaulus with brown mark extending from dorsal end of epicnemial carina anteriorly to mesothoracic venter posteriorly (vs. sternaulus medially yellowish; Fig. 104 View FIGURES 97–104. 97–98 ); ventral half of lower division of metapleuron orange to dark brown (vs. lower division of metapleuron entirely bright yellow); hind coxa entirely orange (vs. dorsally with basal yellow spot).

Female. Unknown.
