Description. Holotype FEMALE. Fore wing length 7.34 mm.  
 Head. Mandible 1.53 as long as basal width, moderately pilose; ventral margin projected as crest; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.76 as wide as high, subrectangular, finely punctate, apically smooth; apex 1.76 as long as base, truncate; apical margin sharp, medially straight. Supraclypeal area entirely strigate, with scarce punctures, moderately pilose; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. Antenna with 28 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 or with stout, median, transversally arched, medially interrupted carina, medially without longitudinal elevation, near antennal sockets 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 regularly shaped, not projected; malar space 1.06 as long as basal width of mandible.   
 Mesosoma. Mesosoma in dorsal view 1.73 as long as wide; in lateral view, mesosoma middle width 0.22 mm. Pronotum centrally smooth, latero-ventrally markedly rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling smooth; collar dorso-laterally carinated, not swollen, anteriorly punctulate; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated, central lobe with dense coarse punctures, central lobe with faint longitudinal carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove markedly corrugated; scutellum 0.94 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.35 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 reaching 0.2 of posterior margin of pronotum, behind epicnemial carina without rounded confused-rugulose area; sternaulus medially shallow, interrupted, reaching base of mid coxa, markedly sinuate, moderately impressed; faintly corrugated; scrobe moderately deep, forming pit with sulcus. Mesothoracic venter coarsely punctate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.12 as long as anterior portion of propodeum, moderately deep and narrow, medially wide, closely corrugated, medially some carinae distinctly stouter; propodeum 1.17 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigate, medially with two posteriorly convergent longitudinal carinae; lateral longitudinal carina of propodeum represented by subcircular carina; posterior portion of propodeum entirely markedly strigate, medially with longitudinal carina; behind posterior transverse carina with two stout parallel longitudinal carinae; anterior transverse carina of propodeum complete, stout, straight; posterior transverse carina absent; propodeal spiracle 1.50 as long as wide; pleural carina of propodeum irregular, fused with sculpture of lower division of metapleuron and propodeum; lower division of metapleuron minutely strigate or sparsely punctate, densely pilose, juxtacoxal carina short and faint.   
 Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs entirely slightly sinuous; vein 1cu-a straight, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.67 as long as vein 2cu-a; vein 4Rs 0.95 as long as vein 4M, sinuous; cell 1+2Rs 1.00 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M indistinct. Hind wing: vein 1Cu 1.52 as long as vein cu-a; vein 2-1A reaching 0.74 of distance to posterior margin.   
 Legs. Tibia with dense short bristles; hind coxa globose.   
 Metasoma. T1 0.49 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.57, prominent; postpetiole dorso-anteriorly convex; T2–8 minutely coriarious; almost glabrous; T2 0.98 as long as wide at apex; apex of T2 2.02 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.   
 Color. Head and mesosoma black and yellow, metasoma ferruginous. Head: black; mouthparts, base of clypeus, supraclypeal area laterodorsally, large complete orbital band, and malar space, dark yellow (232,188,108); clypeus apically, and mandible base and apex, dark brown (109,079,062); scape ventrally dark brown; flagellum brownish towards apex; f5–12 ventrally whitish. 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, base of tegula, upper division of metapleuron, dorsal half of lower division of metapleuron, and hind margin of metanotum, bright yellow; mesopleuron with four small bright yellow spots: at subalar ridge, dorsal half of hypoepimeron, dorsally to epicnemial carina, and ventrally opposite to mesepimeron; posterior portion of propodeum with two lateral longitudinal large yellow stripes. Legs: all coxae black with yellow (229,212,139) spots; fore and mid coxae with large dorsal yellow spot; hind coxa with two yellow spots: dorsal mark large, at basal 0.7, anterior mark small, at basal 0.2; all femora dark yellow (229,167,056), ventrally brown (101,047,022); second trochanter of all legs basally yellow; all tibiae and tarsi yellow, whitish towards apex, except for all t5, dark brown. Metasoma: ferruginous; T1 dorsally to spiracles, black; posterior 0.1 of T1 yellow.   
 Comments. Albeit stated by Townes as near albimaculatus (label data), it can be more easily confused with T. teutonius sp. nov., from which it is differentiated by having mesopleuron with four yellow spots (vs. with three in T. teutonius sp. nov.; Fig. 24); hind margin of metanotum with two lateral teeth (vs. with two short lateral carinae extending towards transverse furrow at base of propodeum); posterior portion of propodeum medially with distinct longitudinal carina; (vs. without; Fig. 145); hind femur orange, ventrally brown (vs. black); metasoma mostly ferruginous (vs. mostly black; Fig. 164).
