Hind wing: vein 1Cu 2.13 as long as vein cu-a; vein 2-1A reaching 0.82 of distance to posterior margin.   
 Legs. Tibia with sparse short bristles; hind coxa elongate.   
 Metasoma. T1 0.47 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.50, prominent; postpetiole dorso-anteriorly flat; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 0.94 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 present.   
 Color. Head, mesosoma and metasoma black and yellow (225,204,101). Head: yellow; mandible apex, malar space, clypeal apex centrally, supra-antennal area medially, interocellar area, vertex and gena, except complete large orbital band, and occiput, black; scape ventrally yellow, dorsally brown; flagellum ventrally entirely brown, dorsally whitish at f9–10. Mesosoma: propleuron light yellow, dorsally black; pronotum black except lateral rounded spots at collar and pronotal swelling, bright yellow; mesoscutum black, except longitudinal lanceolate mark at posterior 0.9 of central lobe; mesopleuron with two large marks: anterior one extending from subalar ridge to entire dorsal margin of sternaulus except around hypoepimeron and just behind epicnemial carina, posterior one at 0.7 dorsal of hypoepimeron; mesothoracic venter with lateral yellow stripe ventrally to sternaulus; remainder of mesosoma black, except for the following bright yellow marks: axillary carina, scutellum, postscutellum, both upper and lower division of metapleuron, and two lateral longitudinal marks at posterior portion of propodeum. Legs: mostly yellow; fore and mid coxae ventrally, and fore and mid femora dorsally and ventrally, brown; all t5 dark brown; hind coxa black with two basally connected yellow marks: anterior mark narrow, posterior mark large, both reaching 0.9 of length of coxa; hind first trochanter and hind femur dark brown, dorsally with narrow yellow stripe. Metasoma: black and yellow; T1 laterally bright yellow, dorsally black with posterior 0.2 bright yellow; T2–8 black with posterior 0.4 bright yellow; S2–8 bright yellow, laterally black.   
 Variation. Antenna with 27–29 flagellomeres, white band at f5–12. Yellow spot at ventral side of scape from distinct to very small, almost fading. Scutoscutellar groove faintly corrugated. Dark mark at mid mesopleuron just behind epicnemial carina sometimes separated from dark mark at epicnecium, sometimes connected. One specimen with mesopleuron just behind epicnemial carina yellow, coloration continuous with large mark extending from subalar ridge to dorsal margin of sternaulus. Surface over sternaulus sometimes partially yellow (sometimes medially, or posteriorly). Mesothoracic venter sometimes completely black, or variously marked with yellowish. Hind coxa ventrally with apical yellow stripe. Hind femur ventrally with basal yellow mark; apical 0.1 yellow. Cell 1+2Rs sometimes distinct, pentagonal; often higher apically.

Dark marks at epicnecium, mesothoracic venter and legs sometimes dark brown (079,037,018) instead of black.   
 Comments. Very similar to T. coaracius sp. nov., from which it is isolated by having collar dorso-laterally carinated, not swollen, as in Fig. 46 (vs. rounded, distinctly swollen in T. coaracius sp. nov., as in Fig. 47); epomia stout (vs. absent); mesopleuron markedly strigate only anteriorly around hypoepimeron (vs. entirely markedly strigate; Fig. 102); sternaulus smooth (vs. corrugated; Fig. 102); hind tibia entirely bright yellow (vs. with apical 0.3 brownish); hind t1 entirely whitish (vs. with basal 0.2 brownish).   
 Male. Similar to female, except as follows. Supraclypeal area with two lateral black stripes reaching antennal foramens; dorsally to clypeus blackish. Antenna with 28 flagellomeres; flagellum completely white at f8–15, partially at f7 and f16. Orbital band sometimes very thin at lower gena, black part of gena almost connected to black malar space. Longitudinal lanceolate yellow mark at central lobe of mesoscutum restricted to posterior 0.3. Mesopleuron just behind epicnemial carina yellowish. Sternaulus entirely black; posterior portion sometimes yellow. Yellow marks at mesothoracic venter narrow. Propodeal sculpturing behind anterior transverse carina stout. Mid femur entirely yellowish. Yellow stripes at hind coxa narrow, sometimes straight, restricted to basal 0.6. Posterior yellow mark at T3–T8 present only laterally. T2 sometimes fuscous, lighter than other tergites. T1–8 sometimes dark brown instead of black.
