Description. Holotype FEMALE. Fore wing length 6.87 mm.

Head. Mandible 1.63 as long as basal width, densely pilose; ventral margin regularly shaped, not projected; dorsal tooth distinctly longer than ventral tooth. Clypeus 1.59 as wide as high, subtriangular, finely punctate; apex 1.55 as long as base, truncate; apical margin blunt, medially straight. Supraclypeal area entirely strigulate, also densely punctate, moderately pilose, medially with longitudinal subrectangular prominent area; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. White band starting at flagellomere 4, reaching flagellomere 11; flagellum somewhat stout; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially punctulate, or strigulate. Paraocular area finely punctulate. Vertex punctate around ocelli, without sulcus; gena and vertex behind ocelli minutely strigulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally uniformly arched, ventrally regularly shaped, not projected, reaching hypostomal carina at mandible base or nearly so; hypostomal carina projected as crest; malar space 1.03 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 1.96 as long as wide; in lateral view, mesosoma middle width 0.19 mm. Pronotum centrally corrugated, latero-ventrally rugose behind collar, margin near mesopleuron not corrugated; pronotal swelling finely rugulose; collar dorso-laterally carinated, not swollen, anteriorly rugulose; epomia very faint, almost indistinct. 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 faintly corrugated; scutellum 2.14 as long as wide, scarcely punctate; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.47 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron dorsally strigate, include over hypoepimeron, ventrally strigulate; mesopleural groove corrugated; epicnemial carina stout, dorsally curving forwards; 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 very shallow, forming sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter V-shaped, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.21 as long as anterior portion of propodeum deep and wide, very markedly corrugated; propodeum 1.14 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum strigulate, medially with two faint parallel longitudinal carinae; lateral longitudinal carina of propodeum indistinct; posterior portion of propodeum confused-rugose, medially without distinctly stout longitudinal carina; anterior transverse carina of propodeum absent; posterior transverse carina represented by pair of high spine-like apophysis, posteriorly curved; apophysis 0.62 as high as wide; propodeal spiracle 1.75 as long as wide; pleural carina of propodeum complete, moderately stout; lower division of metapleuron strigulate, densely pilose, juxtacoxal carina short and faint.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs entirely sinuous; vein 1cu-a almost indistinctly curved, arising far from vein 1M+Rs base, angle with vein M+Cu about 90°; vein 2Cu 0.86 as long as vein 2cu-a; vein 4Rs 0.89 as long as vein 4M, straight; cell 1+2Rs 0.88 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 0.55 as long as vein 2M. Hind wing: vein 1Cu 1.59 as long as vein cu-a; vein 2-1A reaching 0.95 of distance to posterior margin.

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

Metasoma. T1 0.56 as long as hind femur, without basolateral tooth; minutely coriarious; spiracle at anterior 0.56, slightly prominent; postpetiole dorso-anteriorly flat; T2–8 minutely coriarious; almost glabrous; T2 1.10 as long as wide at apex; apex of T2 2.39 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve with series of teeth; notch present.

Color. Head black and whitish, mesosoma fulvous (153,072,037) and metasoma dark brown (081,063,048) with white marks. Head: black; mandible centrally, clypeus and supraclypeal area laterally, ventral half of supraantennal area laterally, large orbital band interrupted before malar space, whitish (230,211,146); mouthparts, mandible base and apex, clypeus apically, and scape ventrally, light brown (179,106,066); flagellum ventrally entirely brown, dorsally entirely whitish at f5–11, partially at f4. Mesosoma : almost completely fulvous; pronotal swelling, axillary carina, tegula, subalar ridge, spot dorsally to epicnemial carina, and apex of apophysis, whitish. Legs: fore leg fulvous, except for tarsus, brown; mid leg brown, with two stripes: the dorsal one yellow, the lateral one whitish; hind leg black, except for the following marks: dorsal spot at coxa, and t1–t5 ventrally, whitish; hind coxa basally with ventral fulvous spot. Metasoma: black; T1 fulvous at anterior 0.1; T2–8 laterally whitish at posterior 0.1.

Comments. Readily differentiated from other species of the genus by the almost completely fulvous mesosoma ( Fig. 40 View FIGURE 40 ), and by lacking anterior transverse carina of propodeum ( Fig. 127 View FIGURES 127–132 ). Similar to T. callangus sp.

nov., from which it is differentiated by having supra-antennal area medially black (vs. completely orange in T. callangus sp. nov.); collar dorso-laterally carinated, not swollen, as in Fig. 46 View FIGURES 45–54. 45 (vs. rounded, distinctly swollen, as in Fig. 47 View FIGURES 45–54. 45 ); juxtacoxal carina short (vs. long).

Male. Unknown.

Distribution. Known only from Ecuador ( Fig. 230 View FIGURES 224–231 ).

Biology. Unknown.

Material examined. Holotype ♀, ECUADOR: Napo, Baeza , 13.II.1983, Lars Huggert leg., Toechorychus, Townes det. 1957 ( AEIC). Complete, in good shape, except for mesoscutum somewhat damaged by pin.
