 Head. Mandible 1.28 as long as basal width, densely pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.93 as wide as high, subrectangular, minutely strigulate, apically smooth; apex 1.39 as long as base, truncate; apical margin sharp, medially straight. Supraclypeal area entirely strigate, with scarce punctures, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. Antenna with 24 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 11; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area with stout, median, longitudinal carina or with stout, median, transversally arched, medially interrupted carina, medially without longitudinal elevation, near antennal sockets striate; dorsal half medially rugulose. Paraocular area smooth. Vertex rugulose around ocelli, at anterior third with short, longitudinal sulcus, posterior two-thirds smooth; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina faint, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina slightly projected as crest; malar space 0.97 as long as basal width of mandible.   
 Mesosoma. Mesosoma in dorsal view 1.96 as long as wide; in lateral view, mesosoma middle width 0.20 mm. Pronotum centrally smooth, latero-ventrally smooth, 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, central lobe with dense coarse punctures, central lobe with faint longitudinal carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove faintly corrugated; scutellum 1.16 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.41 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron entirely markedly strigate, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally curving backwards; dorsal end of epicnemial carina reaching 0.1 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, moderately sinuate, moderately impressed; faintly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter long and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.18 as long as anterior portion of propodeum deep and narrow, medially wide, very faintly corrugated, almost smooth; propodeum 1.18 as long as wide medially; anterior margin of propodeum with two lateral teeth; anterior portion of propodeum strigate or strigulate or with sparse coarse punctures, medially without longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum entirely markedly strigate, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially slightly arched forwards; posterior transverse carina absent; propodeal spiracle 1.80 as long as wide; pleural carina of propodeum absent, apparently present because of sculpture patterns of lower division of metapleuron and propodeum; lower division of metapleuron punctate and strigulate, sparsely pilose, juxtacoxal carina short and faint.   
 Wings. Fore wing: vein 2+3Rs almost straight, apically slightly curved; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.67 as long as vein 2cu-a; vein 4Rs 0.99 as long as vein 4M, sinuous; cell 1+2Rs 1.00 as high as pterostigma, almost indistinct; vein 2M distinctly longer than vein 3M; vein 3M indistinct. Hind wing: vein 1Cu 2.05 as long as vein cu-a; vein 2-1A reaching 0.80 of distance to posterior margin.   
 Legs. Tibia with sparse short bristles; hind coxa globose.   
 Metasoma. T1 0.53 as long as hind femur, with faint basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, slightly prominent; postpetiole dorsally, at level of spiracles, faintly but distinctly concave; T2–8 minutely coriarious; almost glabrous; T2 0.99 as long as wide at apex; apex of T2 2.02 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth.   
 Color. Head and mesosoma yellow and black, metasoma mostly orange. Head: bright yellow (240,217,115); mandible, ventral half of malar space, apex of clypeus, M-shaped mark at ventral half of supraclypeal area, supraantennal area medially, vertex, and occiput, black; scape, pedicel, and flagellum brown; flagellum dorsally entirely white at f6–9 entirely, partially at f5 and f10–11. Mesosoma: black, except for the following bright yellow marks: propleuron ventrally, collar laterally, pronotal swelling, longitudinal narrow mark at posterior 0.8 of central lobe of mesoscutum, tegula basally, axillary carina, scutellum, postscutellum, large mark extending from subalar ridge to posterior dorsal margin of sternaulus except dorsally to epicnemial carina, dorsal 0.8 of hypoepimeron, mesothoracic venter laterally and centrally, upper division of metapleuron, dorsal 0.9 of lower division of metapleuron, hind margin of metanotum centrally, and two lateral longitudinal marks at posterior portion of propodeum. Legs: mostly orange (220,117,056); fore coxa bright yellow, posteriorly fulvous, laterally with light brown spot; mid coxa bright yellow, laterally with dark brown strip at posterior 0.7; hind coxa yellow with three brown spots: anteriorly at basal 0.3, laterally at medial 0.5–0.6, dorsally at entire length; all t5 dark brown. Metasoma: mostly orange (206,097,050); T1 dorsally, and laterally at spiracles, black; laterally, anterior 0.4, and at posterior 0.2, bright yellow; medially, at posterior 0.2, orange.   
 Variation. Antenna with 26 flagellomeres, dorsally entirely white at f5–f11. Dark mark at mid mesopleuron just behind epicnemial carina sometimes separated from dark mark at epicnecium, sometimes connected. Surface over sternaulus sometimes partially yellow medially. Mesothoracic venter either completely yellow or marked with blackish medially and near mesopleuron, forming M-shaped mark, or only medially blackish.   
 Comments. Similar to T. zulius sp. nov. from which can be distinguished by having ventral half of gena yellow (vs. posteriorly brown in T. zulius sp. nov.; Fig. 72); propleuron dorsally black and ventrally pale yellow (vs. completely dark brown); collar dorso-laterally rounded, distinctly swollen, as in Fig. 47 (vs. carinated, not swollen; Fig. 46); mesothoracic venter black with yellow longitudinal stripes (vs. completely dark brown); lower division of metapleuron punctate and strigulate (vs. almost smooth, very faintly strigulate); fore and mid femora entirely orange (vs. ventrally brownish); mid coxa yellow, with dorsal black mark at apical 0.7 (vs. brown with dorsal large yellow mark); hind coxa yellow with three black marks (vs. dark brown with two yellow stripes); spiracle of T1 slightly prominent (vs. prominent); posterior 0.2 of T1 medially orange and laterally pale yellow (vs. pale yellow).
