( Figures 1 View FIGURE 1 A–D, 2A–D, 32)

Diagnosis. Frons strongly divergent, vertex two times wider than base. Postpedicel short, sometimes as long as wide, with same size or shorter than style. Notopleuron paler than adjacent scutum. Abdominal mid stripe broad, series of connected triangles through tergite 6, lateral stripes broad and interrupted through tergite 5 or 6. Sternites banded, black pilose on anterior margins, white pilose on posterior margins. Subcallus brown, not markedly inflated on lateral view.

Holotype female. Length 12.4 mm, wing 9 mm. Eyes bare. Frons pruinescent white, narrow and strongly divergent above (Frontal index (F.I). 8.4, divergence index (D.I.) 2.3). Callus brown, higher than wide. Median callus brown, surrounded by dark pruinescence and hairs. Subcallus only slightly inflated, light brown. Clypeus and gena pale gray and white pilose, except for golden pruinescent spots dorsally. First antennal segment pale yellow, covered with black pilosity, pedicel and postpedicel orange, style dusky. Palpus pruinescent white, white pilose at basal third, remainder black pilose. Proboscis black, covered with pale pruinescence.

Scutum and scutellum with black integument, contrasting light brown at lateral portion including notopleuron and supra-alar area, covered with abundant decumbent golden hairs and sparse erect black hairs. Pleuron with black integument covered with gray pruinescence, and white hairs, except for yellow area on dorsal portion of anepisternum and katepisternum with a tuft of pale yellow hairs. All coxae with yellow integument, gray pruinescence and white hairs, except extreme apex of fore coxa, darker with black hairs. Fore femur brownish with black hairs, mid and posterior tibiae yellow covered with gray pruinescence and white hairs. Fore tibia bicolored, basal half yellowish with pale pilosity, apical half darker with black hairs, mid and hind tibiae yellow with white hairs except for black hairs at apex of mid tibia and fringe of black hairs at hind tibia. All tarsi brown, with black hairs. Wings hyaline, stigma yellowish.

Abdomen brown with black hairs, yellow hairs and pruinescence on tergites lateral margins. Middorsal stripe broad, continuous through segment 6, yellow and yellow pilose. Dorsolateral discontinuous through segment five, faint indications at 6, yellow and yellow pilose. Sternites with brown integument, black median integumental stripe. Sternites 1 and 2 predominantly with black hairs, 3–5 banded, black hairs basally and white hairs on second half, remainder with black hairs.

Male. As in female, except for holoptic eyes, superior 2/3 with enlarged omatidia. Scutum covered with white long hairs. Sternites with white hairs and no black medial stripe.

Comments. The species differs from T. restrepoensis , T. tristichus and T. isis by the darkest legs and interrupted dorsolateral stripes. From T. dorsorufus sp.n. it differs by having a narrower frons and darker integument.
