Description. Holotype ♀. Fore wing length 5.18 mm.

Head. Mandible 1.37 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 2.01 as wide as high, subrectangular, minutely strigulate, apically smooth; apex 1.43 as long as base, truncate; apical margin blunt, medially straight. 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 4, reaching flagellomere 11; flagellum slender; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median 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 minutely strigulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina faint, dorsally absent, ventrally slightly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina slightly projected as crest; malar space 0.77 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 1.76 as long as wide; in lateral view, mesosoma middle width 0.16 mm. Pronotum centrally smooth, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling finely rugulose; collar dorso-laterally rounded, distinctly swollen, anteriorly punctate; 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 without longitudinal sulcus or carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove faintly corrugated; scutellum 0.89 as long as wide, scarcely punctate; 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 entirely markedly strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina faint, dorsally straight; dorsal end of epicnemial carina reaching 0.1 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus medially shallow, interrupted, not reaching base of mid coxa, moderately sinuate, posteriorly almost faint; not corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.30 as long as anterior portion of propodeum, shallow and narrow, medially wide, very faintly corrugated, almost smooth, medially some carinae stouter; propodeum 1.25 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate, medially without 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 divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina represented by crests, present laterally as carina; propodeal spiracle 1.88 as long as wide; pleural carina of propodeum absent; lower division of metapleuron strigulate, sparsely pilose, juxtacoxal carina represented by very short ridges.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a entirely markedly curved, arising near vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.49 as long as vein 2cu-a; vein 4Rs 0.87 as long as vein 4M, straight; cell 1+2Rs 0.9 as high as pterostigma, pentagonal; vein 2M approximately as long as vein 3M; vein 3M distinct, 0.80 as long as vein 2M. Hind wing: vein 1Cu 1.50 as long as vein cu-a; vein 2-1A reaching 0.89 of distance to posterior margin.

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

Metasoma. T1 0.52 as long as hind femur, without basolateral tooth; minutely coriarious; spiracle at anterior 0.57, slightly prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.93 as long as wide at apex; apex of T2 2.16 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve without teeth; notch absent.

Color. Head yellow with black marks, mesosoma orange with black and yellow marks, metasoma mostly orange (206,107,052). Head: pale yellow (238,208,105); mandible teeth, clypeal apex centrally, supra-antennal area medially, interocellar area, vertex, and occiput, black; scape ventrally yellow, dorsally brown; flagellum brown, whitish at f5–7, partially at f4 and f8–10. Mesosoma : orange (229,126,037) with black and yellow (233,207,090) marks; pronotum centrally black, collar laterally and pronotal swelling, pale yellow; mesoscutum black, except longitudinal large mark at entire length of central lobe, anteriorly orange, posteriorly yellow; mesopleuron orange, black between subalar ridge and hypoepimeron, except for the following yellow marks: subalar ridge and epicnecium, dorsal 0.8 of hypoepimeron, and large spot dorsally to 0.6 posterior of sternaulus; axillary trough of mesonotum, black; remaining of mesosoma orange, except for the following yellow marks: axillary carina, scutellum, postscutellum, upper division of metapleuron, central spot at lower division of metapleuron, hind margin of metanotum, and two lateral longitudinal marks at posterior portion of propodeum. Legs: mostly orange; all coxae with dorsal spot at basal 0.2; all t5 dark brown. Metasoma: orange; S1–8 yellow at posterior 0.2; T2 blackish at posterior 0.1.

Comments. Similar to T. morelus sp. nov., from which it is differentiated by having mandible yellow (vs. black in T. morelus sp. nov.; Fig. 71 View FIGURES 70–84 ); supraclypeal area entirely yellow (vs. with M-shaped black mark); mark around hypoepimeron reaching mark over sternaulus (vs. not reaching; Fig. 18 View FIGURES 16–19 ); sternaulus not reaching base of mid coxa (vs. reaching base of mid coxa, even if medially raise); hind coxa orange with dorsal yellow mark at basal 0.1 (vs. yellow with two large black marks; Figs 18 View FIGURES 16–19 and 188 View FIGURES 187–199 ).
