(Figs 31–42)
Diagnosis. Belonging in species group lucida, of Subgroup MPB2A (see Classification below); it is close to T. yanacona González, Carrejo & García Aldrete, differing from it in the shape of the hypandrium, in having the postero-lateral processes stouter and distally rounded, in having a V-shaped promontory anteriorly in the median posterior process, and in having the distal lobes of the median posterior process longer (Fig. 35); also, the posterior arms of the mesal sclerite are slender and longer than in T. yanacona (Fig. 36); IX sternum of two sections, with wide anterior and posterior lobes, anterior half deeply concave in the middle.
Male. Color (in 80% ethanol). Body brown, with cream spots. Head pale brown, with dark brown pattern (Fig. 33). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Maxillary palps pale brown, Mx4 darker. Tergal lobes of meso- and metathorax brown; pleurae dark brown, with cream spots. Fore- coxae brown, with small dark spots anteriorly and posteriorly; mid and hind- coxae cream, with small brown spots anteriorly and posteriorly; trochanters cream; femora cream, with distal brown spots in mid- and hind- legs; tibiae and tarsi pale brown. Forewing pattern (Fig. 31). Pterostigma with proximal and distal brown bands; a pale brown submarginal pigmented band from R 4+5 to CuA 1. Hindwings hyaline (Fig. 32). Abdomen pale brown, with cream areas; hypandrium pale brown; endophallic sclerites dark brown.
Morphology. As in diagnosis, plus the following: Head (Fig. 33): H/MxW: 1.56; H/D: 2.05; IO/MxW: 0.50. Vertex slightly emarginate, slightly below the level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with four-five wide denticles. Mx4/Mx2: 1.67. Forewings (Fig. 31): L/W: 2.49. Pterostigma: lp/wp: 4.31. Areola postica slanted posteriorly: la/ha: 1.78, CuA 1 gently concave distally. Hindwings (Fig. 32): l/p: 2.87. Hypandrium (Fig. 35) of three sclerites. Phallosome (Fig. 36) with side struts slender, Y-shaped, independent, straight distally; anterior endophallic sclerites stout, narrowing distally, each anteriorly bilobed, with an acuminate process on outer border, near the anterior end, directed posteriorly; lateral sclerites curved, dilated distally, truncate. Mesal endophallic sclerite with anterior arms long, slender, distally acuminate; posterior arms distally acuminate, each with a pre-apical tooth on outer border; pair of posterior sclerites transverse, with acuminate processe directed outward. Paraprocts oval, with medium and short setae and macrosetae on apical third, at least two macrosetae with spatulate apices, a macroseta near each sensory field, these with 26 trichobothria on basal rosettes (Fig. 34). Epiproct (Fig. 34) wide, convex anteriorly, rounded posteriorly, setae as illustrated.

Morphology. Head (Fig. 39): H/MxW: 1.54, H/D: 2.41; IO/MxW: 0.65. Vertex as in the male. Outer cusp of lacinial tips broad, with five denticles. Mx4/Mx2: 1.30.

Gonapophyses (Fig. 42): v1 slender, elongate, acuminate; v2+3: v2 with 13 macrosetae, distal process sinuous, acuminate, with field of microspines. Paraprocts (Fig. 40) elongate, triangular, with setae as illustrated; sensory fields with 27 trichobothria on basal rosettes. Epiproct (Fig. 40) triangular, apex rounded, mesal field with three macrosetae, two lateral setae and macrosetae along sides and apex, as illustrated.
