Description. Holotype FEMALE. Fore wing length 5.75 mm.

Supraclypeal area entirely strigulate, also densely punctate, moderately pilose, medially slightly prominent; between antennal foramens with V-shaped carina, medially interrupted; radicle foveolate. Antenna with 24 flagellomeres; white band starting at flagellomere 6, reaching flagellomere 12; flagellum slender; subapical flagellomeres slightly flattened. Supra-antennal area without distinct median carina, medially without longitudinal elevation, near antennal sockets not striate; dorsal half medially scarcely punctulate. Paraocular area smooth. Vertex with very coarse punctures around ocelli, without sulcus; gena and vertex behind ocelli punctulate, sparsely pilose; gena in lateral view uniformly wide; occipital carina stout, dorsally V-shaped, ventrally markedly projected as crest, reaching hypostomal carina far from mandible base; hypostomal carina projected as crest; malar space 0.97 as long as basal width of mandible.

Mesosoma . Mesosoma in dorsal view 2.14 as long as wide; in lateral view, mesosoma middle width 0.17 mm. Pronotum centrally smooth, latero-ventrally rugose behind collar, margin near mesopleuron ventrally markedly corrugated; pronotal swelling finely rugulose; collar dorso-laterally carinated, not swollen, anteriorly punctulate; epomia stout, restricted to space between posterior margin of collar and pronotal swelling. Mesoscutum sparsely pilose, densely punctulate, covered with sparse coarse punctures, impression of notaulus corrugated, central lobe without longitudinal sulcus or carina; notauli deeply impressed, posteriorly parallel throughout. Scutoscutellar groove markedly corrugated; scutellum 0.98 as long as wide, smooth; scutellar carina incomplete, restricted approximately to anterior 0.3; postscutellum 0.39 as long as wide; hind margin of metanotum without teeth or carinae. Subalar ridge somewhat elongate; mesopleuron dorsally strigate, ventrally 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 with rounded confused-rugulose area; sternaulus complete, reaching base of mid coxa, markedly sinuate, moderately impressed; faintly corrugated; scrobe moderately deep, forming pit with sulcus. Mesothoracic venter punctate and strigulate; median portion of posterior transverse carina of mesothoracic venter short and straight, regularly shaped, without projections. Transverse furrow at base of propodeum laterally 0.08 as long as anterior portion of propodeum deep and narrow, medially wide, very faintly corrugated, almost smooth, medially some carinae stouter; propodeum 1.31 as long as wide medially; anterior margin of propodeum without teeth; anterior portion of propodeum finely strigulate, medially without longitudinal carinae; lateral longitudinal carina of propodeum indistinct; 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, medially slightly arched forwards; posterior transverse carina absent; propodeal spiracle 1.83 as long as wide; pleural carina of propodeum present only posteriorly; 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 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 0.64 as long as vein 2cu-a; vein 4Rs 0.98 as long as vein 4M, straight; cell 1+2Rs 0.81 as high as pterostigma, pentagonal; vein 2M approximately as long as vein 3M; vein 3M distinct, 0.57 as long as vein 2M. Hind wing: vein 1Cu 2.05 as long as vein cu-a; vein 2-1A reaching 0.92 of distance to posterior margin.

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

Metasoma. T1 0.52 as long as hind femur, without basolateral tooth; anteriorly smooth, posteriorly coriarious; spiracle at anterior 0.55, prominent; postpetiole dorsally, at level of spiracles, faintly but distinctly concave; T2–8 minutely coriarious; centrally almost glabrous, laterally pilose; T2 0.93 as long as wide at apex; apex of T2 2.28 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 (223,205,146). Head: pale yellow; mandible teeth, supra-antennal area medially, interocellar area, vertex and gena, except complete large orbital band, and occiput, pale brown (182,074,039); scape ventrally yellow; scape dorsally, pedicel and flagellum, brown; flagellum dorsally whitish at f6–14, partially at f15. Mesosoma : propleuron pale yellow, posteriorly pale brown; pronotum pale brown except lateral stripe 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 along entire length of sternaulus; remainder of mesosoma pale yellow, except for the following pale brown marks: both axillary trough of mesonotum and metanotum, carinal triangle, upper division of metapleuron centrally, anterior portion of propodeum, and three lateral longitudinal marks at propodeum: medially, and laterally along pleural carinae. Legs: bright yellow; all t5 dark brown; fore and mid t1–t4 dorsally pale brown; hind coxa with two basally not connected brown marks: dorsal mark somewhat anchor–shaped reaching apex, and ventral mark large, at basal 0.6. Metasoma: brown and pale yellow; T1 brown, anterior and lateral 0.3 bright yellow; posterior 0.1 of T1 pale yellow; T2 orange at anterior 0.6, brown at medial 0.7, and pale yellow at posterior 0.3; T3–8 brown with posterior 0.4 pale yellow; S1 bright yellow; S2–8 pale yellow, laterally brown.

Variation. Confused-rugulose area faint. Rounded spot just behind epicnemial carina brown, smaller than in the holotype. Differences in tonality include variations from orange (210,122,052) to dark brown (141,059,033).

Comments. Similar to T. martinus sp. nov., from which it is separated by having transverse furrow at base of propodeum very faintly corrugated, almost smooth (vs. uniformly corrugated in T. martinus sp. nov.; Fig. 136 View FIGURES 133–138 ); anterior margin of propodeum without tooth (vs. with two lateral teeth, as in Fig. 51 View FIGURES 45–54. 45 ); lateral longitudinal carina of propodeum indistinct (vs. represented by short curved carina); anterior transverse carina of propodeum medially slightly arched forwards (vs. straight; Fig. 136 View FIGURES 133–138 ); pleural carina of propodeum present only posteriorly (vs. irregular but complete, fused with sculpture of propodeum and lower division of metapleuron); T1 without basolateral tooth, as in Fig. 54 View FIGURES 45–54. 45 (vs. with two basolateral teeth, as in Fig. 53 View FIGURES 45–54. 45 ).

Male. Unknown.

Distribution. Brazil. Recorded from two localities from Santa Catarina ( Fig. 223 View FIGURES 216–223 ). The type locality is Nova Teutônia (27°11’S 52°23’W); the other locality probably refers to the municipality of Águas Mornas, formerly “Teresópolis.” These records comprise a range of 0°30’ in latitude.

Biology. Unknown.
