Supraclypeal area entirely strigate, with scarce punctures, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with U-shaped carina; radicle foveolate. Antenna with 21 flagellomeres; white band starting at flagellomere 5, reaching flagellomere 12; flagellum slender; subapical flagellomeres as wide as basal flagellomeres, not flattened. Supra-antennal area with very faint but distinct median longitudinal 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 with scarce punctures, sparsely pilose; gena in lateral view at level of dorsal portion of occipital carina narrow, ventrally wide; occipital carina faint, dorsally absent, ventrally markedly projected as crest, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 1.00 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 1.98 as long as wide; in lateral view, mesosoma middle width 0.23 mm. Pronotum centrally corrugated, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling finely rugulose; collar dorso-laterally carinated, not swollen, anteriorly punctate; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum densely pilose, lobes dorsally rugulose, impression of notaulus markedly corrugated, central lobe with sparse coarse punctures, central lobe with faint longitudinal carina; notauli deeply impressed, posteriorly convergent. Scutoscutellar groove faintly corrugated; scutellum 0.78 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.33 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 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, deeply impressed; faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter coarsely punctate, or strigulate; median portion of posterior transverse carina of mesothoracic venter long and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.10 as long as anterior portion of propodeum, moderately deep and moderately narrow, medially wide, markedly corrugated; propodeum 1.07 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigate, medially with two posteriorly convergent faint longitudinal carinae; lateral longitudinal carina of propodeum represented by faint but distinct subcircular carina; posterior portion of propodeum markedly strigate, striation medially arched backwards, 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 absent; propodeal spiracle 1.60 as long as wide; pleural carina of propodeum irregular and faint, obsolescent posteriorly, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron minutely strigate or sparsely punctate, sparsely pilose, juxtacoxal carina short and stout.

Wings. Fore wing: vein 2+3Rs almost straight, apically slightly curved; ramellus absent; vein 1M+Rs posteriorly faintly sinuous; vein 1cu-a posteriorly slightly curved, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.65 as long as vein 2cu-a; vein 4Rs 1.11 as long as vein 4M, slightly sinuous, almost straight; cell 1+2Rs 0.76 as high as pterostigma, rectangular; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.50 as long as vein 2M. Hind wing: vein 1Cu 2.25 as long as vein cu-a; vein 2-1A reaching 0.79 of distance to posterior margin.

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

Metasoma. T1 0.52 as long as hind femur, without basolateral tooth; minutely coriarious; spiracle at anterior 0.52, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.98 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 present.

Color. Head, mesosoma and metasoma black with yellow marks. Head: black; mouthparts, mandible centrally, clypeus basally, supraclypeal area latero-dorsally, large but incomplete orbital band, dark yellow (207,148,077); clypeus apically, and mandible base and apex, dark brown (077,044,025); scape ventrally dark brown; flagellum ventrally entirely brown, dorsally whitish at f5–12. Mesosoma : black; lateral small mark at collar, pronotal swelling, longitudinal lanceolate mark at posterior 0.3 of central lobe of mesoscutum, axillary carina, scutellum, postscutellum, tegula, upper division of metapleuron, large mark at dorsal half of lower division of metapleuron, and hind margin of metanotum centrally, bright yellow; mesopleuron with four small bright yellow spots: at subalar ridge, dorsal half of hypoepimeron, dorsally to epicnemial carina, and opposite to mesepimeron; posterior portion of propodeum with two lateral longitudinal large yellow stripes. Legs: all coxae black with yellow (202,147,068) spots; fore and mid coxae with large dorsal yellow spot; hind coxa with two yellow spots: dorsal spot large, at basal 0.7, lateral spot small, at basal 0.2; first trochanter of all legs apically yellow; fore and mid femora dark yellow (204,133,069), ventrally brown (101,082,060); hind femur dark brown, apical 0.1 yellow; all tibiae and tarsi yellow, except for all t5, dark brown. Metasoma: black; T1 and T2 yellowish at posterior 0.1.

Comments. Similar to T. taperinus sp. nov., from which it is differentiated by having mesopleuron with three yellow spots (vs. with four in T. taperinus sp. nov.; Fig. 100 View FIGURES 97–104. 97–98 ); hind margin of metanotum with two short lateral carinae extending towards transverse furrow at base of propodeum (vs. with two lateral distinct teeth); posterior portion of propodeum medially without longitudinal carina; (vs. with distinct longitudinal carina; Fig. 159 View FIGURES 157–162 ); hind femur black (vs. orange, ventrally brown); metasoma mostly black (vs. mostly ferruginous).

Male. Unknown.

Distribution. Known only from Brazil ( Fig. 227 View FIGURES 224–231 ). Biology. Unknown. Material examined. Holotype ♀, BRAZIL: Santa Catarina, Nova Teutônia, II.1953, Fritz Plaumann leg. (AEIC). Left antenna beyond scape, and right hind leg beyond tibia, missing; mesoscutum somewhat damaged by pin; otherwise in good shape.
