Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina wide, ventrally narrow; occipital carina stout, dorsally faint, uniformly arched, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 0.97 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.05 as long as wide; in lateral view, mesosoma middle width 0.18 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron not corrugated; pronotal swelling strigulate; collar dorso-laterally carinated, not swollen, anteriorly punctulate; epomia absent. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove smooth, polished; scutellum 1.21 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.46 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat rounded; mesopleuron dorsally strigate only before hypoepimeron, centrally polished, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally straight; dorsal end of epicnemial carina reaching 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed, faint at posterior 0.5; faintly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter V-shaped, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.24 as long as anterior portion of propodeum deep and wide, uniformly corrugated; propodeum 1.21 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate or with sparse coarse punctures, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum markedly strigate, striation medially arched backwards, 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, only with a lateral slight swellings; propodeal spiracle 1.25 as long as wide; pleural carina of propodeum complete, moderately stout; lower division of metapleuron faintly strigulate, sparsely pilose, juxtacoxal carina short and faint.

Wings. Fore wing: vein 2+3Rs almost straight; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a straight, arising at vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.62 as long as vein 2cu-a; vein 4Rs 0.95 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.74 as high as pterostigma, pentagonal; vein 2M approximately as long as vein 3M; vein 3M distinct, 0.89 as long as vein 2M. Hind wing: vein 1Cu 1.75 as long as vein cu-a; vein 2-1A reaching 0.8 of distance to posterior margin.

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

Metasoma. T1 0.56 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.51, prominent; postpetiole dorso-anteriorly flat; T2–8 minutely coriarious; almost glabrous; T2 1.04 as long as wide at apex; apex of T2 1.74 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch absent.

Color. Head, mesosoma and metasoma pale yellow (218,182,108) with black marks. Head: pale yellow; mandible teeth, supra-antennal area between antennal foramen, interocellar area, vertex and gena, except complete large orbital band, and occiput, black; scape ventrally yellow; scape dorsally, pedicel and flagellum, brown; flagellum completely whitish at f4–8, apically at f3, and dorsally at f9–10. Mesosoma : propleuron pale yellow, dorsally with small black spot; pronotum black except lateral rounded spot at collar and pronotal swelling, pale yellow; mesoscutum black, except longitudinal rectangular mark at posterior 0.9 of central lobe; mesopleuron pale yellow with three black marks: anteriorly around hypoepimeron, at mesopleural groove, and ventrally almost faint, along sternaulus; remainder of mesosoma black, except for the following bright yellow marks: axillary carina, scutellum, postscutellum, both upper and lower division of metapleuron, mesothoracic venter and two lateral longitudinal marks at posterior portion of propodeum, over propodeal swelling. Legs: mostly yellow; all t5 brown; fore coxa, fore trochanter, dorsal spot at mid coxa, and hind tarsomeres, white. Metasoma: black, brown and whitish (239,224,189); T1 black, laterally and at posterior 0.2, whitish; T2–8 black with lateral and posterior 0.4 whitish; S1 white; S2–8 whitish, laterally with brown spots.

Variation. Posterior portion of propodeum with two lateral slight rounded swellings. Pleural carina stouter than in the holotype. T1 anteriorly white, medially orange. Differences in tonality include variations from whitish (239,224,189) to pale yellow (218,182,108).

Comments. Similar to T. pirrus sp. nov., from which it is isolated by having epomia absent (vs. stout, restricted to space between posterior margin of collar and pronotal swelling in T. pirrus sp. nov.); lateral lobes of mesoscutum entirely black (vs. anteriorly with yellow marks; Fig. 86 View FIGURES 85–90 ); hind margin of metanotum without teeth or carinae, as in Fig. 48 View FIGURES 45–54. 45 (vs. with two short lateral carinae extending towards transverse furrow at base of propodeum, as in Fig. 49 View FIGURES 45–54. 45 ); scrobe very shallow, forming a sulcus (vs. deeply impressed, forming a pit); posterior portion of propodeum medially without distinctly stout longitudinal carina (vs. with two stout longitudinal carina; Fig. 156 View FIGURES 151–156 ); hind coxa entirely orange (vs. yellow with dorsal black stripe).
