Clypeus 1.78 as wide as high, rectangular, minutely strigulate, apically smooth; apex 1.35 as long as base, truncate; apical margin sharp, medially slightly concave. Supraclypeal area medially strigate, laterally finely punctate, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with U-shaped carina, medially widely interrupted; radicle foveolate. Antenna with 30 flagellomeres; white band starting at flagellomere 6, reaching flagellomere 11; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median carina or with stout, median, transversally arched, medially interrupted carina, medially with small rounded 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 with scarce punctures, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina stout, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 0.82 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 1.82 as long as wide; in lateral view, mesosoma middle width 0.24 mm. Pronotum centrally smooth, latero-ventrally markedly strigate behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling smooth; collar dorso-laterally carinated, not swollen, anteriorly punctate; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe with faint longitudinal carina; notaulus moderately impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 0.8 as long as wide, densely punctate; scutellar carina incomplete, restricted approximately to anterior 0.6; postscutellum 0.33 as long as wide; hind margin of metanotum with two lateral teeth. Subalar ridge somewhat rounded; mesopleuron entirely markedly strigate; mesopleural groove corrugated; epicnemial carina stout, dorsally straight; dorsal end of epicnemial carina not reaching ventral margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, almost straight, moderately impressed; faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter punctate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.30 as long as anterior portion of propodeum, moderately deep and narrow, medially wide, markedly corrugated; propodeum 0.98 as long as wide medially; anterior margin of propodeum with two faint lateral teeth; anterior portion of propodeum confused-rugose, medially without longitudinal carinae; lateral longitudinal carina of propodeum represented by subcircular carina; posterior portion of propodeum entirely markedly strigate, medially longitudinally swollen; behind posterior transverse carina with two divergent longitudinal carinae; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina absent; propodeal spiracle 1.4 as long as wide; pleural carina of propodeum absent; lower division of metapleuron strigate, sparsely pilose, juxtacoxal carina stout, medially interrupted.

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 about 90°; vein 2Cu 0.69 as long as vein 2cu-a; vein 4Rs 1.03 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.86 as high as pterostigma, almost indistinct; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.38 as long as vein 2M. Hind wing: vein 1Cu 1.19 as long as vein cu-a; vein 2-1A reaching 0.77 of distance to posterior margin.

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

Metasoma. T1 0.56 as long as hind femur, with faint basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.56, prominent; postpetiole dorso-laterally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; almost glabrous; T2 0.75 as long as wide at apex; apex of T2 2.09 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch absent.

Color. Head and mesosoma black and yellow; metasoma mostly orange. Head: bright yellow (231,208,111); mandible apex, clypeal apex, two longitudinal marks extending from anterior tentorial pit to supraclypeal area around medial rectangular swelling, supraclypeal area ventrally, supra–antennal medially, vertex centrally, and occiput, black; scape, pedicel, and flagellum, dark brown (098,066,048); flagellum at f5–7 dorsally partially whitish. Mesosoma : black, except for the following yellow marks (226,206,111): propleuron ventrally, collar laterally, pronotal swelling, longitudinal lanceolate mark at posterior 0.5 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, tegula, large mark extending from subalar ridge to posterior 0.7 of dorsal margin of sternaulus, subcircular spot dorsally at hypoepimeron, mesothoracic venter centrally, both upper and lower division of metapleuron, hind margin of metanotum, and two large lateral longitudinal marks at posterior portion of propodeum, yellow. Legs: mostly orange; fore and mid coxae dorsally yellow at basal 0.7 and 0.5, respectively; hind coxa with two not connected yellow marks, the dorsal one at basal 0.5, the anterior one at basal 0.1; all t5 dark brown. Metasoma: dark orange (182,079,031); posterior 0.1 of T1 yellow.

Variation. Face with only faint, oblique black marks. Mesothoracic venter black. General tones of yellow “cream”. One specimen from Jataí , Goiás, with sculpturing and rugulosities at pronotum and mesopleuron fainter than in the holotype .

Comments. Similar to T. albimaculatus , especially due to the color pattern, and is readily differentiated from it by having pleural carina of propodeum absent, as in Fig. 42 View FIGURES 41–44. 41 (vs. present only posteriorly in T. albimaculatus ); juxtacoxal carina stout, medially interrupted (vs. absent); angle between fore wing veins 1cu-a and M+Cu about 90° (vs. distinctly obtuse; Fig. 105 View FIGURE 105–118 ); T1 with faint basolateral tooth ( Fig. 53 View FIGURES 45–54. 45 ) (vs. without; Fig. 54 View FIGURES 45–54. 45 ).

Male. Very similar to female.

Distribution. Brazil. Recorded from Pará and Goiás ( Fig. 237 View FIGURES 232–239 ). The type locality is Santarém, Pará (2°54’S 54°20’W). These records comprise a range of 14°58’ in latitude.

Biology. Unknown.
