Color. Head, mesosoma and metasoma pale yellow (224,193,112) with black marks. Head: yellow; mouthparts, mandible teeth, interocellar area, vertex and gena, except complete large orbital band and stripe between ocelli and vertex, and occiput, black; scape ventrally yellow, dorsally brown; flagellum brown, except for f6–15, completely white and f16, partially whitish. Mesosoma : mostly light yellow, except for the following black marks: pronotum only centrally, center of posterior margin of pronotum, inner half of lateral lobes of mesoscutum, scutoscutellar groove, base of postscutellum, both axillary trough of mesonotum and metanotum, transverse mark anteriorly around hypoepimeron, carinal triangle, anterior portion of propodeum, apex of juxtacoxal area, and three longitudinal narrow stripes at propodeum, central one along median longitudinal carina, lateral ones along pleural carina.

Variation. Flagellum brown, except for f6–14, completely white, and f5 and f15, partially whitish. Black mark at ocellar triangle sometimes reaching black mark at vertex. Posterior margin of pronotum sometimes black, either connected or not with median brown mark dorsal to collar. Yellow mark at outer half of lateral lobe of mesoscutum often reaching axillary carina.

Vein 2-1A short, reaching only about 0.5 of distance to posterior margin. T1 dorsally to spiracle yellowish. Differences in tonality include variations from pale yellow (224,193,112) on most specimens to bright yellow (242,231,125) on one specimen from Aracruz (Espírito Santo).

Comments. Very similar to T. tumazulus sp. nov., from which it differs by having central lobe of mesoscutum with faint longitudinal carina (vs. without sulcus or carina in T. tumazulus sp. nov.); posterior portion of propodeum medially with swollen longitudinal carina (vs. without distinctly stout longitudinal carina; Fig. 149 View FIGURES 145–150 ); yellow mark at lateral lobe of mesoscutum reaching well beyond tegula (vs. restricted to 0.2 anterior of lateral lobe; Fig. 88 View FIGURES 85–90 ); pleural carina irregular and faint, obsolescent posteriorly, fused with sculpture of propodeum and lower division of metapleuron (vs. complete, moderately stout, as in Fig. 41 View FIGURES 41–44. 41 ); transverse furrow at base of propodeum laterally wide (vs. narrow); T1 light yellow, with black mark restricted to spiracle level (vs. T1 almost entirely black, except for anterior and posterior 0.1, bright yellow).
