 Head. Mandible 1.63 as long as basal width, densely pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.65 as wide as high, subrectangular, finely punctate; apex 1.43 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area entirely densely punctate, densely pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with Vshaped carina, medially interrupted; radicle foveolate. Antenna with 23 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 11; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially rugulose. Paraocular area finely punctulate. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli minutely strigulate, densely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally V-shaped, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 0.91 as long as basal width of mandible.   
 Mesosoma. Mesosoma in dorsal view 1.98 as long as wide; in lateral view, mesosoma middle width 0.18 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling strigulate; collar dorso-laterally rounded, distinctly swollen, anteriorly punctulate; epomia stout, ending at pronotal swelling. Mesoscutum sparsely pilose, densely punctulate, covered with sparse coarse punctures, impression of notaulus corrugated, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 1.11 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.6; postscutellum 0.31 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron dorsally strigate, ventrally rugulose; mesopleural groove corrugated; epicnemial carina faint, dorsally straight; 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, deeply impressed; faintly corrugated; scrobe very shallow, forming sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.16 as long as anterior portion of propodeum deep and moderately narrow, medially wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.09 as long as wide medially; anterior margin of propodeum with two faint lateral teeth; anterior portion of propodeum finely strigulate, medially with two posteriorly convergent faint longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum before posterior transverse carina medially confused-rugose and laterally punctulate, behind strigaterugose, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, medially slightly arched forwards; posterior transverse carina complete, medially arched, laterally with low swelling; propodeal spiracle 1.45 as long as wide; pleural carina of propodeum absent, apparently present because of sculpture patterns of lower division of metapleuron and propodeum; lower division of metapleuron strigulate, densely pilose, juxtacoxal carina short and faint.   
 Wings. Fore wing: vein 2+3Rs slightly sinuous; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.68 as long as vein 2cu-a; vein 4Rs 0.90 as long as vein 4M, straight; cell 1+2Rs 0.80 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M indistinct. Hind wing: vein 1Cu 2.2 as long as vein cu-a; vein 2-1A reaching 0.80 of distance to posterior margin.   
 Legs. Tibia with sparse short bristles; hind coxa globose.   
 Metasoma. T1 0.55 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.58, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.98 as long as wide at apex; apex of T2 2.08 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 whitish, fulvous and black, with yellow marks. Head: whitish; mouthparts, mandible, clypeal apex, supraclypeal area laterally just posteriorly to clypeus, supra-antennal area only posteriorly to scape, interocellar area, vertex and gena, except complete large orbital band, and occiput, brown (090,057,027); scape yellow (195,136,093); pedicel light brown; flagellum ventrally entirely brown, dorsally completely whitish at f6–9, partially at f5 and f10. Mesosoma: mostly fulvous (166,099,055); propleuron yellow; pronotum fulvous except collar laterally and pronotal swelling, pale yellow, and posterior 0.1 of collar, black; mesoscutum fulvous, except longitudinal lanceolate mark at posterior 0.2 of central lobe; mesopleuron fulvous with three pale yellow marks: along epicnecium from subalar ridge to dorsal end of epicnemial carina, and dorsally and ventrally to scrobe, respectively; mesothoracic venter fulvous with lateral light brown (136,076,030) stripe ventrally to sternaulus; axillary carina, scutellum, upper division of metapleuron, dorsal half of lower division of metapleuron, pale yellow; anterior portion of propodeum fulvous, except for first pleural area, black; posterior portion of propodeum black, with two lateral longitudinal marks from crests to posterior margin of propodeum. Legs: fore and mid legs dark yellow (213,154,072); all coxae with dorsal subcircular pale yellow spot, all t5 black; hind coxa and femur ferruginous (145,085,049), hind femur dorsally brownish; hind tibia dark yellow; hind t1–4 light yellow, whitish towards apex. Metasoma: black, white and ferruginous; T1–2 black, with lateral and posterior 0.2 whitish; T3–8 fulvous, with posterior 0.5 whitish; S2–8 pale brown, with posterior 0.4 white.   
 Variation. Antenna with 24 flagellomeres; flagellum dorsally whitish at f5–9, sometimes reaching flagellomere 10 or 11. Mandible sometimes completely brown, sometimes mostly yellow with brown base and apex. Supraclypeal area often entirely yellowish, or medially black, except for two small spots ventrally to antennal foramens. Area at and around scrobe sometimes blackish, sometimes brown (as remainder of mesopleuron). Apical yellow stripe at T1 sometimes medially narrow. Anterior portion of propodeum blackish around spiracle. Dorsal yellow spot at hind coxa lighter. Differences in tonality include variations from whitish to pale yellow, and from fulvous (166,099,055) to dark brown (083,051,029). One specimen from Parque Estadual do Rio Doce with anterior portion of propodeum entirely black and apical yellow stripe of T1 centrally interrupted.   
 Comments. Color pattern very similar to some T. cassunungae specimens, from which it can be distinguished by having juxtacoxal carina of mesopleuron long (vs. short in T. cassunungae); pale yellow marks dorsally and ventrally to scrobe always separated from other marks at mesopleuron (vs. variously connected to other marks); hind femur dorsally dark (vs. uniformly colored, generally dark yellow); T1 always laterally pale yellow, except around spiracle (Figs 1 and 179) (vs. variously colored; Fig. 16); mesoscutum always concolorous with anterior portion of propodeum (vs. sometimes not concolorous).
