Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly abruptly curved, Ushaped. Scutoscutellar groove markedly corrugated; scutellum 0.92 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.29 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron entirely markedly strigate; 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 complete, reaching base of mid coxa, markedly sinuate, moderately impressed, faint from anterior 0.7 to 0.8, markedly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter convex, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.11 as long as anterior portion of propodeum, moderately deep and narrow, very faintly corrugated, almost smooth, medially some carinae stouter; propodeum 1.14 as long as wide medially; anterior margin of propodeum with two faint lateral teeth; anterior portion of propodeum strigulate, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum entirely markedly strigate, medially without distinctly stout longitudinal carina; anterior transverse carina of propodeum complete, stout, medially markedly arched forwards; posterior transverse carina absent; propodeal spiracle 1.67 as long as wide; pleural carina of propodeum present only posteriorly; lower division of metapleuron strigate, sparsely pilose, juxtacoxal carina short and faint.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs posteriorly faintly sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.57 as long as vein 2cu-a; vein 4Rs 0.88 as long as vein 4M, uniformly slightly convex; cell 1+2Rs 0.75 as high as pterostigma, rectangular; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.75 as long as vein 2M. Hind wing: vein 1Cu 1.48 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 globose.

Metasoma. T1 0.45 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 1.00 as long as wide at apex; apex of T2 2.13 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve without teeth; notch present.

Color. Head, mesosoma and metasoma black and pale yellow (230,191,109). Head: pale yellow; mandible teeth, clypeal apex, supra-antennal area, interocellar area, vertex and gena, except complete large orbital band, and occiput, black; scape ventrally yellow, dorsally brown; flagellum ventrally entirely brown, dorsally totally whitish at f6–15, partially at f5 and f14. Mesosoma : propleuron pale yellow; pronotum black except lateral rounded spots at collar and pronotal swelling, pale yellow; mesoscutum black, except pale yellow longitudinal lanceolate mark at posterior 0.9 of central lobe; mesopleuron pale yellow with three black marks: extending anteriorly around hypoepimeron, at mesopleural groove, and over sternaulus; mesothoracic venter between epicnemial carina and posterior transverse carina of mesothoracic venter, pale yellow; remainder of mesosoma black, except the following pale yellow marks: scutellar carina, scutellum, postscutellum, both upper and lower division of metapleuron, and two lateral longitudinal marks at posterior portion of propodeum. Legs: fore and mid legs pale yellow; all femora anteriorly and posteriorly brown striped; all t5 dark brown; mid coxa dorsally with apical small brown spot; hind coxa with two longitudinal black marks, ventral one extending at basal 0.4, dorsal one anchor–shaped, reaching apex of coxa; hind tibia yellow at basal 0.8, apical 0.2 dark brown (128,090,065); hind t1 black at basal 0.2, apically white; t2–4 white. Metasoma: black and yellow; T1 black, at posterior 0.2 and laterally, yellow (except basally and at spiracle); T2–8 black with posterior 0.4 pale yellow; S1 black; S2–8 pale yellow, laterally black.

Variation. Antenna with 26–27 flagellomeres. Scutoscutellar groove smooth, larger. Black mark over sternaulus medially or anteriorly interrupted. Transverse furrow at base of propodeum medially with some stouter carinae. Anterior transverse carina of propodeum medially straight. Dorsal stripe at fore and mid femora lighter. Dorsal stripe at mid coxa sometimes absent. Dorsal stripe at hind coxa brownish; apically narrower. Basal 0.2 of hind t1 brownish. T1 brownish at anterior 0.1. Differences in tonality include variations from whitish (230,191,109) to pale yellow, and from dark brown (128,090,065) to black.

Comments. Very similar to T. itapuensis sp. nov., from which it is isolated by having collar dorso-laterally rounded, distinctly swollen (vs. carinated, not swollen in T. itapuensis sp. nov., as in Fig. 46 View FIGURES 45–54. 45 ); epomia absent (vs. stout); mesopleuron entirely markedly strigate ( Fig. 102 View FIGURES 97–104. 97–98 ) (vs. markedly strigate only anteriorly around hypoepimeron); sternaulus corrugated (vs. smooth); hind tibia with apical 0.3 brownish (vs. entirely bright yellow); hind t1 with basal 0.2 brownish (vs. entirely whitish).

Male. Similar to female, except as follows. Supraclypeal area laterally with two brown marks. Scuto-scutellar groove very faintly corrugated. Sternaulus yellow, medially with a rounded black spot. Anterior portion of propodeum medially with longitudinal depression between median longitudinal carinae. Dorsal stripe at mid coxa occupying apical 0.7. Dorsal stripe at hind coxa rectangular, not anchor-shaped. Hind femur entirely brown, darker towards apex.

Distribution. Suriname and Brazil. Recorded from six localities ( Fig. 213 View FIGURES 208–215 ). The type locality is Coaraci, Bahia (14°38’29”S 39°33’40”W). These records comprise a range of 14°15’ in latitude.

Biology. Unknown.
