Head. Mandible 1.69 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.82 as wide as high, rectangular, finely punctate; apex 1.33 as long as base, truncate; apical margin sharp, medially straight. Supraclypeal area entirely strigulate, also densely punctate, moderately pilose, medially with oval prominent area; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. Antenna with 22 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 11; flagellum slender; 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 punctulate. Paraocular area finely punctulate. Vertex punctate 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 regularly shaped, not projected, reaching hypostomal carina at mandible base or nearly so; hypostomal carina regularly shaped, not projected; malar space 1.62 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.05 as long as wide; in lateral view, mesosoma middle width 0.17 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling strigulate; collar dorso-laterally rounded, distinctly swollen, anteriorly rugulose; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, densely punctulate, covered with sparse coarse punctures, impression of notaulus corrugated, central lobe with longitudinal sulcus; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove smooth, polished; scutellum 0.82 as long as wide, densely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.45 as long as wide; hind margin of metanotum without teeth or carinae. 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, reaching base of mid coxa, markedly sinuate, moderately impressed; not corrugated; scrobe moderately deep, forming pit with 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 0.23 as long as anterior portion of propodeum, moderately deep and moderately narrow, medially wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.11 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 indistinct; posterior portion of propodeum mostly smooth, with widely spaced carinae, medially with two stout longitudinal carina; behind posterior transverse carina with two stout parallel longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina represented by high conical apophyses; apophysis 1.00 as high as wide; propodeal spiracle 1.50 as long as wide; pleural carina of propodeum complete, moderately stout; lower division of metapleuron faintly strigulate, sparsely 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 slightly curved, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.73 as long as vein 2cu-a. Hind wing: vein 1Cu 1.4 as long as vein cu-a; vein 2-1A reaching 0.66 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 0.54, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.96 as long as wide at apex; apex of T2 2.18 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.

Color. Head and mesosoma black and pale yellow; metasoma brownish (080,045,027) and pale yellow. Head: pale yellow, except for the following black marks: mandible except rounded basal spot, malar space, clypeal apex, supraclypeal area around clypeus, supra-antennal area medially, interocellar area, vertex and gena except large complete orbital band, and occiput, black; scape, pedicel, and flagellum, dark brown (070,047,030); flagellum at f6–9 dorsally whitish, partially at f5. Mesosoma : black, except for the following pale yellow marks (225,187,105): propleuron medially, collar laterally, pronotal swelling, longitudinal lanceolate mark at posterior 0.3 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, tegula basally, subalar ridge, dorsal 0.8 of hypoepimeron, large triangular mark ventral to scrobe, small triangular mark dorsal to epicnemial carina, longitudinal stripe at mesothoracic venter ventrally to anterior 0.6 of sternaulus, upper division of metapleuron, hind margin of metanotum medially, dorsal 0.6 of lower half of metanotum, and conical apophysis, yellow. Legs: mostly dark yellow (219,156,090); fore and mid coxae brown (086,059,045), dorsally yellow at apical 0.9 and 0.7, respectively; hind coxa and hind trochanter, black; hind coxa with two longitudinal marks at basal 0.9, anterior mark narrow, posterior mark large; hind second trochanter, fore and mid tarsi, apical 0.3 of hind tibia ventrally, hind tarsus ventrally, brown. Metasoma: mostly brown; T1 black, posterior 0.1 pale yellow; T2–8 pale yellow at posterior 0.2; S2–5 medially orange.

Comments. This species has the most different color pattern among the species of the genus, and is easily recognizable by the propodeum completely black, only with pale yellow over the high conical apophyses ( Fig. 126 View FIGURES 119–126. 119–114 ), whereas other species have a slightly varied pattern of longitudinal stripes at posterior portion of propodeum. The sculpturing of posterior portion of propodeum is also unique and characteristic for the species, only similar to T. calius sp. nov. ( Fig. 143 View FIGURES 139–144 ) from which it can be readily separated by having supra-antennal area without transverse carina (vs. with stout, median, arched transverse carina in T. calius sp. nov.); central lobe of mesoscutum with longitudinal sulcus (vs. without sulcus or carina); T1 black, except 0.2 posterior, pale yellow (vs. yellow, except dorsally to spiracle, black; Fig. 190 View FIGURES 187–199 ).
