Supraclypeal area medially strigate, laterally and medially finely punctate, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens without V-shaped carina; radicle foveolate. White band starting at flagellomere 6, reaching flagellomere 9; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area with stout, median, arched, transverse carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially rugulose. Paraocular area finely strigulate. Vertex rugulose around ocelli, without sulcus; gena and vertex behind ocelli minutely strigulate, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina stout, dorsally faint, V-shaped, ventrally slightly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.03 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.11 as long as wide; in lateral view, mesosoma middle width 0.2 mm. Pronotum centrally corrugated, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling strigulate; collar dorso-laterally rounded, distinctly swollen, anteriorly punctulate; epomia stout, ending at pronotal swelling. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 0.93 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.44 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron dorsally medially markedly strigate, ventrally 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 with rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, deeply impressed; markedly 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 0.14 as long as anterior portion of propodeum, moderately deep and narrow, medially wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.10 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate, medially without longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum confused-rugose, medially with two stout longitudinal carina; anterior transverse carina of propodeum complete, stout, entirely slightly arched forwards; posterior transverse carina represented by pair of high conical apophysis; apophysis 1.10 as high as wide; propodeal spiracle 1.63 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron strigulate, densely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs uniformly curved; vein 1cu-a straight, arising near vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.80 as long as vein 2cu-a; vein 4Rs 0.82 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.76 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 1.08 as long as vein 2M. Hind wing: vein 1Cu 4.33 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 0.57 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.52, prominent; postpetiole dorso-laterally, behind spiracles, markedly concave, deeply depressed; T2–8 punctate, posteriorly coriarious; centrally almost glabrous, laterally pilose; T2 0.93 as long as wide at apex; apex of T2 1.87 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 black with yellow (245,231,127) marks. Head: black; labrum, clypeus apicolaterally, radicle dorsally, ventral stripe at scape, large orbital band, interrupted only at malar space, yellow; flagellum dorsally totally whitish at f6–10, partially at f5. Mesosoma : black, except for the following yellow marks: propleuron ventrally, collar laterally, pronotal swelling, large longitudinal lanceolate mark at posterior 0.8 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, upper division of metapleuron, lower division of metapleuron centrally, two lateral longitudinal marks at propodeum, and four marks at mesopleuron: subalar ridge, ventral half of epicnecium, hypoepimeron, and elongate spot ventrally to scrobe. Legs: mostly orange; all t5 black; fore and mid coxae black, anteriorly with large basal spot; hind coxa yellow with two longitudinal black marks: dorsal mark anchor-shaped, apically connected with ventral large mark, both at entire length of coxa; hind first trochanter blackish. Metasoma: black and yellow; T1 yellow, except for rounded spot opposite to spiracle; T2–8 black with posterior 0.4 yellow; S1 black; S2–8 pale yellow, laterally black.

Comments. Similar to T. amazonensis sp. nov., mainly due to the mesopleuron color pattern, from which it can be isolated by having supra-antennal area with stout, median, arched, transverse carina (vs. without transverse carina in T. amazonensis sp. nov.); posterior portion of propodeum with two longitudinal yellow stripes ( Fig. 143 View FIGURES 139–144 ) (vs. black, only marked with yellow on conical swellings; Fig. 126 View FIGURES 119–126. 119–114 ) central lobe of mesoscutum without sulcus or carina (vs. with longitudinal sulcus); lower division of metapleuron centrally yellow (vs. with ventral half black); T1 yellow, except dorsally to spiracle, black (vs. black, except 0.2 posterior, pale yellow).
