Description. Holotype FEMALE. Fore wing length 6.71 mm.
Head. Mandible 1.79 as long as basal width, moderately pilose; ventral margin slightly projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.57 as wide as high, subtriangular, minutely strigulate, apically smooth; apex 1.35 as long as base, slightly but distinctly convex; apical margin sharp, medially slightly concave. Supraclypeal area entirely strigate, with scarce punctures, moderately pilose, medially slightly prominent; between antennal foramens with three, complete, U-shaped carinae; radicle foveolate. Antenna with 26 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 10; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area with very faint but distinct median longitudinal carina, medially without longitudinal elevation, near antennal sockets striate; dorsal half medially strigulate. Paraocular area smooth. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli smooth, glabrous; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina stout, dorsally absent, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.15 as long as basal width of mandible.
Mesosoma . Mesosoma in dorsal view 2.23 as long as wide; in lateral view, mesosoma middle width 0.21 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling smooth; collar dorso-laterally carinated, not swollen, anteriorly smooth; epomia absent. Mesoscutum densely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove faintly corrugated; scutellum 1.2 as long as wide, smooth; scutellar carina complete, posteriorly closing; postscutellum 0.29 as long as wide; hind margin of metanotum with two lateral teeth. Subalar ridge somewhat elongate; mesopleuron dorsally medially markedly strigate, ventrally smooth; 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 medially shallow, interrupted, reaching base of mid coxa, moderately sinuate, moderately impressed, faint from anterior 0.6 to 0.9, faintly corrugated; scrobe moderately deep, forming pit with sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.08 as long as anterior portion of propodeum deep and narrow, very faintly corrugated, almost smooth; anterior margin of propodeum with two faint lateral teeth; propodeum 1.24 as long as wide medially; anterior portion of propodeum finely strigulate, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum strigate, progressively coarse toward posterior margin, medially with longitudinal carina until midlength; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina absent; propodeal spiracle 2.00 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 very faintly strigulate, sparsely pilose, juxtacoxal carina short and stout.
Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs entirely irregular; vein 1cu-a straight, arising near vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.76 as long as vein 2cu-a; vein 4Rs 0.92 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.96 as high as pterostigma, rectangular; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.35 as long as vein 2M. Hind wing: vein 1Cu 1.37 as long as vein cu-a; vein 2-1A reaching 0.89 of distance to posterior margin.
Legs. Tibia with sparse short bristles; hind coxa globose.
Metasoma. T1 0.53 as long as hind femur, with basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, prominent; postpetiole dorsally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 0.87 as long as wide at apex; apex of T2 2.07 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 yellow and dark brown, metasoma orange. Head: bright yellow (243,227,126); 0.8 of mandible, ventral half of malar space, apical half of clypeus, supraclypeal area ventrally, supra-antennal area, interocellar area, vertex and gena, except complete large orbital band, and occiput, dark brown (124,082,058); scape, pedicel, and flagellum brown, blackish toward apex; f6–9 entirely white, f10 almost entirely white, f5 partially white. Mesosoma : brown with whitish marks (244,231,204); propleuron brown; pronotum dark brown except collar laterally and pronotal swelling, pale yellow; mesoscutum black except longitudinal pale yellow lanceolate mark at posterior 0.5 of central lobe; remainder of mesosoma dark brown, except for the following pale yellow marks: axillary carina, tegula apically, scutellum, postscutellum, large mark extending from subalar ridge to entire dorsal margin of sternaulus except around hypoepimeron, dorsal half of hypoepimeron, upper division of metapleuron, 0.5 dorsal of lower division of metapleuron, and two lateral longitudinal marks at posterior portion of propodeum, pale yellow. Legs: mostly brown; fore and mid coxae with large dorsal pale yellow spot; fore and mid trochanters pale yellow, posteriorly brown; fore and mid femora posteriorly with brown stripe; all tibia, and all t1–t4, yellow; hind coxa dark brown with two pale yellow marks, anterior one narrow, at basal 0.7, posterior one large and dorsal, almost reaching apex of coxa, basally wide; hind first trochanter mostly brownish, posteriorly yellow. Metasoma: mostly orange (221,126,036); T1 ferruginous (183,095,052), posterior 0.2 pale yellow; T2–8 and S2–8 uniformly orange. 0.7 dorsal of lower division of metapleuron yellow.

Comments. Similar to T. kawus sp. nov., from which can be separated by having ventral half of gena posteriorly brown (vs. yellow in T. kawus sp. nov.; Fig. 79 View FIGURES 70–84 ); propleuron completely dark brown (vs. dorsally black and ventrally pale yellow); collar dorso-laterally carinated, not swollen, as in Fig. 46 View FIGURES 45–54. 45 (vs. rounded, distinctly swollen, as in Fig. 47 View FIGURES 45–54. 45 ); mesothoracic venter completely dark brown (vs. black with yellow longitudinal stripes); lower division of metapleuron almost smooth, very faintly strigulate (vs. punctate and strigulate); fore and mid femora ventrally brownish (vs. entirely orange); mid coxa brown with dorsal large yellow mark (vs. yellow, with dorsal black mark at apical 0.7); hind coxa dark brown with two yellow stripes (vs. yellow with three black marks); spiracle of T1 prominent (vs. slightly prominent); posterior 0.2 of T1 pale yellow (vs. T1 medially orange and laterally pale yellow; Fig. 165 View FIGURES 163–174 ).
