(Figs 43–54)
Diagnosis. It belongs in species group lucida, of Subgroup MPB2A (see Classification below). It is close to the Peruvian T. tambopatensis García Aldrete, from which it differs in lacking a circular protuberance mesally on each arm of the posterior process of the central sclerite of the hypandrium, and in the phallosome sclerites (compare Figs 47 and 48 in this paper, with Figs 60 and 62 in García Aldrete, 1999). Central sclerite of hypandrium with meso-lateral processes short, distally truncate; median posterior process divided in two stout arms, slightly dilated distally. Side struts of phallosome V-shaped, slender, independent; anterior endophallic sclerite large, obtusely convex anteriorly, posteriorly with irregular shoulders and a broad, median posterior process, distally pointed. Lateral endophallic sclerites stout, straight, club-shaped, much wider anteriorly. Mesal sclerite large, wide, with two long, anterolateral pointed processes, two short, pointed postero-lateral processes, and a median stout posterior process, distally truncate. External parameres broad, distally rounded, with a long, distally acuminate process on inner border. IX sternum wider than long, with rounded angles, anterior border is slightly concave.
Male. Color (in 80% ethanol). Body brown to cream. Head pale brown, with dark brown spots pattern (Fig. 45). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; antennae pale brown; maxillary palps pale brown. Thorax brown, tergal lobes of meso- and metathorax brown with cream spots. Thoracic mesopleura brown, with small cream spots. Legs light brown; coxae with dark spots basally and distally, femora with small dark spots distally; tibiae and tarsi light brown. Forewings almost hyaline, with brown spots at vein ends, at wing margin; pterostigma with dark brown bands proximally and distally; a pale brown submarginal pigmented band from R 4+5 to areola postica (Fig. 43). Hindwings hyaline, veins pale brown, with brown spots at ends of veins R and M (Fig. 44). Abdomen cream with ochre spots. Epiproct and paraprocts light brown. Sclerites of hypandrium pale brown, lateral sclerites darker than central sclerite. Endophallic sclerites dark brown.
Morphology. As in diagnosis, plus the following: Head (Fig. 45): H/MxW: 1.79; H/D: 2.42; IO/MxW: 0.58. Vertex slightly emarginate, at the level of the upper edge of the compound eyes. Outer cusp of lacinial tips broad, with four denticles. Mx4/Mx2: 1.22. Forewings (Fig. 43): L/W: 2.49. Pterostigma: lp/wp: 4.82. Areola postica triangular: la/ha: 1.88, CuA 1 gently concave distally. Hindwings (Fig. 44): l/p: 2.80. Hypandrium (Fig. 47) of three sclerites. Phallosome (Fig. 48), side struts slender, V-shaped, external parameres broad, with rounded apices and few observable pores. Median process of mesal endophallic sclerite with small denticles apically. Paraprocts oval, with abundant medium and short setae on apical third, a macroseta near each sensory field, these with 22 trichobothria on basal rosettes (Fig. 46). Epiproct (Fig. 46) wide, broadly rounded posteriorly, setae as illustrated.
