Description. Adult. Colouration. Head and thorax dirty whitish to yellowish. Vertex with dark margins along eyes and dark midline; antennal insertions dark. Antenna whitish, with apex of segment 8 as well as entire segments 8 and 9 dark brown. Thorax with margins of sclerites dark. Forewing yellowish, semi-transparent to opaque, with indistinct brown dots covering the whole membrane; apices of veins Rs, M1+2, M3+4 and Cu1a concolorous with surrounding area, apex of Cu1b with a dark dot (Figs 4, 13). Hindwing semi-transparent, whitish. Abdomen yellowish, slightly lighter ventrally; apex of paramere dark brown.

Structure. Vertex (Figs 41, 55) 1.7 times as wide as long, surface finely punctured. Antenna (Fig. 69) with one subapical rhinarium on each of segments 4, 6, 8 and 9; segments 4, 6, and 9 slightly thicker than segment 3; relative length of antennal flagellar segments = 1.0/ 0.4/ 0.3/ 0.3/ 0.4/ 0.4/ 0.3/ 0.3; terminal antennal setae about 1.7 and 1.1 times as long as segment 10. Pronotum transverse, short, about 4 times as wide as long, very slightly curved backwards at the sides; suture of propleurites with only one dorsal branch developed. Meso- and metascutellum forming distinctly, slightly transversely raised tubercles. Metacoxa bearing flattened tubercular meracanthus and long cylindrical membranous process on the trochanteral cavity; metatibia with an open crown of 6 apical sclerotised spurs. Forewing (Figs 4, 13) subrhomboidal, vein C+Sc weakly concave, slightly widened, costal break developed, membrane transversely rugose, semi-transparent to opaque; surface spinules (Fig. 27) arranged in small groups surrounded by a cellular pattern lacking spinules; radular spinules forming a narrow, indistinct band along the wing margin. Genitalia as in Figs 94, 107, 120, 133, 144. Male subgenital plate, in profile, subrectangular with angular dorsal margin. Paramere almost straight, weakly curved backwards; inner face bearing a group of strongly sclerotised black pegs in apical half. Distal portion of aedeagus weakly inflated apically. Female proctiger cuneate, subacute apically. Subgenital plate sparsely pilose ventrally, subacute apically.

Head width (HW) 0.84–0.94 (0.89±0.07), antenna length (AL) 0.86, forewing length (WL) 1.82–1.90 (1.86±0.06), metatibia length (TL) 0.58–0.68 (0.63±0.07), male proctiger length (MP) 0.3, paramere length 0.22, length of distal segment of aedeagus 0.20, female proctiger length (FP) 1.06.—AL/HW 1.02, WL/HW 2.02–2.17 (2.09±0.10), WL/forewing width 1.98–2.79 (2.39±0.58), metafemur length/TL 0.47–0.59 (0.53±0.08), TL/HW 0.69–0.72 (0.71±0.02), MP/HW 0.40, FP/HW 1.13, FP/circumanal ring length 4.08, FP/subgenital plate length 1.71.

Fifth instar immature unknown.

Etymology. From Greek ἁπλοῦς = single, simple, sound, perfect, referring to simple morphology not displaying any eye-catching differences to its close relatives T. maculipectus and T. orientalis .

Distribution. Brazil (Rio Grande do Sul, Santa Catarina).

Host plants. Adults were collected on Schinus ferox Hassl. and S. longifolia (Lindl.) Speg. (Anacardiaceae) which are likely hosts.
