Variation. Scutoscutellar groove faintly corrugated. Rounded spot just behind epicnemial carina joining posterior black mark at sternaulus. Anterior portion of propodeum brownish around spiracle. Longitudinal stripes at posterior portion of propodeum brownish towards apex. Posterior black spot at hind coxa absent. Mid coxa dorsally entirely yellowish. T1 dorsally orange.

Comments. Very similar to T. vilhenus sp. nov., from which it can be separated by having supraclypeal area with two lateral longitudinal stripes ( Fig. 66 ) (vs. entirely yellow in T. vilhenus sp. nov.); supra-antennal area with distinct median longitudinal carina (vs. without distinct median carina); supra-antennal area medially without elevation (vs. with small rounded elevation); occipital carina dorsally absent ( Fig. 50 ) (vs. conspicuous and uniformly arched, as in Fig. 52 ); mesopleuron ventrally and sternaulus, yellow (vs. with rounded black spot just behind epicnemial carina, and along posterior half of sternaulus; Fig. 99 ); hind coxa dorsally yellow (vs. entirely orange; Fig. 172 ); T1 with basolateral tooth, as in Fig. 53 (vs. without, as in Fig. 54 ). Also similar to T. darienus sp. nov., from which it can be differentiated by having supraclypeal area with two lateral longitudinal black stripes (vs. ventrally with M-shaped mark in T. darienus sp. nov.; Fig. 78 ); lateral black stripes at supraclypeal area not reaching antennal foramens (vs. reaching antennal foramens, even medially interrupted); malar space completely yellow (vs. ventrally black); occipital carina near mandible bright yellow (vs. black); juxtacoxal carina of mesopleuron faint and short (vs. stout and long); scrobe very shallow, forming a sulcus (vs. deeply impressed, forming a pit); lower division of metapleuron entirely yellow (vs. with ventral rounded black spot; Fig. 30 ); mid and hind coxae mostly yellow to orange (vs. with conspicuous black marks).
