Paraocular area finely punctulate. Vertex rugulose 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 markedly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 1.00 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.00 as long as wide; in lateral view, mesosoma middle width 0.19 mm. Pronotum centrally smooth, latero-ventrally rugulose 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 sparsely pilose, lobes dorsally punctulate, laterally markedly corrugated or covered with sparse coarse punctures, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly abruptly curved, U-shaped. Scutoscutellar groove faintly corrugated; scutellum 1.04 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.46 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat rounded; mesopleuron dorsally medially markedly strigate, ventrally strigulate; 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 medially shallow, interrupted, reaching base of mid coxa, markedly sinuate, moderately impressed, faint from anterior 0.6 to 0.8, faintly corrugated; scrobe deeply impressed, forming pit. Mesothoracic venter strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.16 as long as anterior portion of propodeum, moderately deep and narrow, uniformly corrugated; propodeum 1.14 as long as wide medially; anterior margin of propodeum with two lateral teeth; anterior portion of propodeum finely strigulate or punctulate or with sparse coarse punctures, medially without longitudinal carinae; lateral longitudinal carina of propodeum represented by short curved carina; posterior portion of propodeum entirely markedly strigate, 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 2.00 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 faint.

Wings. Fore wing: vein 2+3Rs slightly concave; ramellus absent; vein 1M+Rs entirely irregular; vein 1cu-a posteriorly slightly curved, arising far from vein 1M+Rs base, angle with vein M+Cu distinctly obtuse; vein 2Cu 0.57 as long as vein 2cu-a; vein 4Rs 0.94 as long as vein 4M, straight; cell 1+2Rs 0.83 as high as pterostigma, pentagonal; vein 2M distinctly longer than vein 3M; vein 3M distinct, 1.00 as long as vein 2M. Hind wing: vein 1Cu 1.64 as long as vein cu-a; vein 2-1A reaching 0.89 of distance to posterior margin.

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

Metasoma. T1 0.52 as long as hind femur, with basolateral tooth; minutely coriarious; spiracle at anterior 0.51, prominent; postpetiole dorso-laterally, behind spiracles, markedly concave, deeply depressed; T2–8 minutely coriarious; almost glabrous; T2 1.16 as long as wide at apex; apex of T2 1.74 as wide as base. Dorsal valve of ovipositor with nodus indistinct; apex of lower valve without teeth; notch present.

Color. Head, mesosoma and metasoma brown and pale yellow (216,155,084). Head: pale yellow; malar space ventrally, mandible apex, clypeal apex, supraclypeal area ventrally, supra-antennal area medially, interocellar area, vertex and gena, except complete large orbital band, and occiput, pale brown (184,125,077); scape ventrally yellow, dorsally brown; pedicel and flagellum ventrally, brown; flagellum dorsally whitish at f6–8, partially at f5 and f9. Mesosoma : propleuron pale yellow, dorsally black; pronotum pale brown except lateral rounded spot at collar and pronotal swelling, pale yellow; mesoscutum pale brown, except longitudinal lanceolate mark at posterior 0.8 of central lobe; mesopleuron pale yellow with four pale brown marks: anteriorly around hypoepimeron, at mesopleural groove, rounded spot just behind epicnemial carina, and over posterior 0.6 of sternaulus; remainder of mesosoma pale yellow, except for the following brown (111,070,048) marks: both axillary trough of mesonotum and metanotum, carinal triangle, anterior portion of propodeum, and three lateral longitudinal marks at propodeum: medially, and along pleural carinae. Legs: yellow; all t5 dark brown; mid coxa dorsally with small apical brown spot; hind coxa with two basally not connected brown marks: dorsally anchor–shaped stripe reaching apex, and ventrally rounded large mark reaching basal 0.6. Metasoma: brown and pale yellow; T1 brown, both anterior and posterior 0.1 pale yellow; T2–8 brown with posterior 0.4 pale yellow; S1 brown; S2–8 pale yellow, laterally black.

Variation. Median longitudinal brown stripe at posterior portion of propodeum large. Hind femur anteriorly and posteriorly brownish. T1 laterally pale yellow at anterior 0.4. Differences in tonality include variations from light brown (111,070,048) to black, and from whitish (230,206,126) to pale yellow (216,155,084).

Comments. Similar to T. catarinus sp. nov., from which it is isolated by having transverse furrow at base of propodeum uniformly corrugated (vs. very faintly corrugated, almost smooth in T. catarinus sp. nov.; Fig. 132 View FIGURES 127–132 ); anterior margin of propodeum with two lateral teeth, as in Fig. 51 View FIGURES 45–54. 45 (vs. without, as in Fig. 48 View FIGURES 45–54. 45 ); lateral longitudinal carina of propodeum represented by short curved carina (vs. indistinct); anterior transverse carina of propodeum straight (vs. medially slightly arched forwards); pleural carina of propodeum irregular but complete, fused with sculpture of propodeum and lower division of metapleuron (vs. present only posteriorly); T1 with basolateral tooth, as in Fig. 53 View FIGURES 45–54. 45 (vs. without, as in Fig 54 View FIGURES 45–54. 45 ).
