(Figs 11, 86, 156, 197)  
Description. Holotype FEMALE. Fore wing length 5.18 mm.  
 Head. Mandible 1.52 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.56 as wide as high, subrectangular, finely punctate; apex 1.56 as long as base, truncate; apical margin sharp, medially slightly convex. Supraclypeal area entirely densely punctate, dorsally also strigulate, moderately pilose, medially slightly prominent; between antennal foramens without Vshaped carina; radicle foveolate. Antenna with 21 flagellomeres; white band starting at flagellomere 1, reaching flagellomere 15; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supraantennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets striate; dorsal half medially rugulose. Paraocular area smooth. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli punctulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina faint, dorsally uniformly arched, ventrally slightly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 1.03 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 corrugated, latero-ventrally rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling finely rugulose; collar dorso-laterally carinated, not swollen, anteriorly rugulose; 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 smooth, polished; scutellum 0.82 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.33 as long as wide; hind margin of metanotum with two short lateral carinae extending towards transverse furrow at base of propodeum. 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 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus incomplete, not reaching base of mid coxa, markedly sinuate, moderately impressed; faintly corrugated; scrobe deeply impressed, forming pit. 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 0.33 as long as anterior portion of propodeum, moderately deep and moderately narrow, medially wide, markedly corrugated; propodeum 1.19 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate or with sparse coarse punctures, medially with two posteriorly convergent longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum markedly strigate, striation medially arched backwards, medially with two stout longitudinal carina or longitudinally swollen; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina absent, only with lateral slight swellings; propodeal spiracle 1.75 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron faintly strigulate, sparsely pilose, juxtacoxal carina absent.   
 Wings. Fore wing: vein 2+3Rs almost straight, apically slightly curved; ramellus absent; vein 1M+Rs anteriorly faintly sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.56 as long as vein 2cu-a; vein 4Rs 0.93 as long as vein 4M, sinuous; cell 1+2Rs 0.81 as high as pterostigma, pentagonal; vein 2M approximately as long as vein 3M; vein 3M distinct, 0.55 as long as vein 2M. Hind wing: vein 1Cu 1.59 as long as vein cu-a; vein 2-1A reaching 0.93 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-laterally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; almost glabrous; T2 0.97 as long as wide at apex; apex of T2 2.30 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.   
 Color. Head, mesosoma and metasoma pale yellow (221,186,119) with black marks. Head: pale yellow; mandible teeth, interocellar area, vertex centrally, and occiput, black; scape ventrally, pedicel ventrally and flagellum ventrally, entirely pale yellow, whitish towards apex; flagellum completely whitish at f5–14, apically at f4, and dorsally at f15–16. Mesosoma: mostly pale yellow, except for the following black marks: ventral 0.1 of propleuron, pronotum centrally, margin of central lobe of mesoscutum, lateral lobes of mesoscutum posteriorly, scutoscutellar groove, both axillary trough of mesonotum and metanotum, small mark between subalar ridge and hypoepimeron, scrobe, carinal triangle, anterior portion of propodeum, posterior portion of propodeum medially, and along pleural carina. Legs: mostly yellow (221,139,044); all t5 brown; fore and mid coxae dorsally with apical brown mark; hind coxa dorsally with longitudinal black stripe at entire length; hind second trochanter ventrally brown. Metasoma: pale yellow with black marks; T1 dorsally black opposite to spiracles; T2–3 black at anterior 0.5; T4–8 blackish medially at anterior 0.1–0.2.   
 Comments. Very similar to T. bombuscarus sp. nov., from which it is differentiated by having epomia stout, restricted to space between posterior margin of collar and pronotal swelling (vs. very faint, almost indistinct in T. bombuscarus sp. nov.); sternaulus not reaching base of mid coxa, as in Fig. 43 (vs. reaching base of mid coxa, as in Fig. 44); pleural carina of propodeum irregular, fused with sculpture of propodeum and lower division of metapleuron (vs. complete, moderately stout, as in Fig. 41); all legs yellowish, except coxae and hind trochanters (vs. dorsally with brown stripe); T4–8 only medially black at anterior 0.1 (vs. black at anterior 0.4).
