Clypeus 1.38 as wide as high, subrectangular, minutely strigulate, apically smooth; apex 1.13 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area medially strigate, laterally and medially finely punctate, densely pilose, medially with oval prominent area; between antennal foramens with V-shaped carina; radicle foveolate. Antenna with 27 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 11; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with very faint but distinct median longitudinal carina, medially with small rounded elevation, near antennal sockets striate; dorsal half medially rugulose. Paraocular area smooth. Vertex rugulose around ocelli or with very coarse punctures around ocelli, without sulcus; gena and vertex behind ocelli smooth, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally absent, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.00 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.01 as long as wide; in lateral view, mesosoma middle width 0.25 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron ventrally corrugated; pronotal swelling strigulate; collar dorso-laterally carinated, not swollen, anteriorly punctate; epomia very faint, almost indistinct. Mesoscutum densely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe with dense coarse punctures, central lobe without longitudinal sulcus or carina; notaulus moderately impressed, posteriorly convergent. Scutoscutellar groove smooth, polished; scutellum 0.99 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.28 as long as wide; hind margin of metanotum with two short lateral carinae extending towards transverse furrow at base of propodeum. Subalar ridge somewhat elongate; mesopleuron entirely densely punctate, ventrally strigulate; 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 incomplete, not reaching base of mid coxa, moderately sinuate, moderately impressed, faint from anterior 0.6 to 0.9, faintly corrugated; scrobe deeply impressed, forming pit. 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 0.12 as long as anterior portion of propodeum, shallow and very wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.18 as long as wide medially; anterior margin of propodeum with two lateral teeth; anterior portion of propodeum posteriorly strigate, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum confused-rugose, medially without distinctly stout longitudinal carina; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina complete, medially arched, laterally with low swelling; propodeal spiracle 2.57 as long as wide; pleural carina of propodeum present only posteriorly; lower division of metapleuron strigate, densely pilose, juxtacoxal carina short and faint.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.57 as long as vein 2cu-a; vein 4Rs 0.98 as long as vein 4M, sinuous; cell 1+2Rs 1.3 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.78 as long as vein 2M. Hind wing: vein 1Cu 1.34 as long as vein cu-a; vein 2-1A reaching 0.94 of distance to posterior margin.

Legs. Tibia with very sparse short bristles; hind coxa globose.

Metasoma. T1 0.51 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, prominent; postpetiole dorso-laterally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 1.08 as long as wide at apex; apex of T2 1.98 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch absent.

Color. Head black and yellow, mesosoma mostly orange and metasoma black with yellow marks. Head: yellow; mandible apex, clypeus apex, median longitudinal stripe at dorsal half of supraclypeal area, supra-antennal area, interocellar area, vertex except large incomplete orbital band, entire gena, and occiput, black. Mesosoma : orange (222,111,048); pronotum bright brown (087,054,036) except for pronotal swelling, yellow; mesoscutum black, except longitudinal rectangular mark at entire length of central lobe; remainder of mesosoma orange, except for the following yellow marks: axillary carina, scutellum, postscutellum, tegula, crests of propodeum, and large mark extending along epicnecium from subalar ridge to posterior end of epicnemial carina. Legs: orange (224,126,052), yellowish towards apex; all t5 dark brown. Metasoma: black and yellow; T1 bright brown, postpetiole anteriorly brown, posteriorly yellow; T2–8 black with posterior 0.1 pale yellow; S2–8 yellow, laterally black.

Variation. No variation observed.

Comments. Color pattern very similar to T. marcapatus sp. nov., from which it can be distinguished by having dorsal half of supraclypeal area with median longitudinal stripe ( Fig. 74 View FIGURES 70–84 ) (vs. supraclypeal area entirely pale yellow); collar dark brown (vs. pale yellow; Fig. 36 View FIGURES 36–39 ); gena ventrally and malar space, black (vs. pale yellow); mesopleuron orange, except for subalar ridge and epicnecium, pale yellow (vs. with black mark anteriorly around hypoepimeron; Fig. 42 View FIGURES 41–44. 41 ); posterior transverse carina of propodeum complete, laterally with crest (vs. absent); pleural carina of propodeum present only posteriorly (vs. absent).

Male. Unknown.

Distribution. Suriname and Brazil. Recorded from two localities ( Fig. 210 View FIGURES 208–215 ). The type locality is Vilhena, Rondônia (12°44’26”S 60°8’45” W). These records comprise a range of 17°54’ in latitude.

Biology. Unknown.
