Triplocania fabridiazi n. sp. Male

(Figs 73–78)

Diagnosis. It belongs in species group lucida, of Subgroup MPB2A (see Classification below). It is close to T. alfonsoi Silva-Neto, Moreira de Castro & Rafael,with which it shares having the same forewing pattern, and having the setae of the veins arising from brown areolae. It differs from it in having the central sclerite of the hypandrium with a tuft of macrosetae on each lateral mesal process, and in having the median posterior process only slightly bilobed distally (Fig. 77). The phallosome and endophallic sclerites are quite distinct in both species (Fig. 78).

Color (in 80% ethanol). Body pale brown. Head pale brown, with dark brown to ochre spots pattern (Fig. 75). Compound eyes brown; ocelli hyaline, with ochre centripetal crescents; antennae pale brown, flagellomeres with cream apices; maxillary palps pale brown, Mx4 darker. Thorax pale brown, with small brown spots on tergal lobes of meso- and metathorax; pleurae light brown, with small ochre spots. Coxae, trochanters and femora cream, tibiae and tarsi pale brown. Forewings mostly hyaline, pterostigma pale brown, with a large, hyaline median area; veins pale brown, a pale brown spot on vein ends (Fig. 73). Hindwings hyaline, veins pale brown (Fig. 74). Abdomen creamy, with few pale brown subcuticular spots; hypandrium, paraprocts and epiproct pale brown; endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head (Fig. 75): H/MxW: 1.39; H/D: 2.54; IO/MxW: 0.74. Vertex slightly emarginate, above the upper border of the compound eyes. Outer cusp of lacinial tips broad, with four wide denticles. Mx4/Mx2: 1.28. Forewings (Fig. 73): L/W: 2.48. Pterostigma: lp/wp: 3.78. Areola postica tall, triangular, almost reaching M, la/ha: 1.77, CuA 1 straight distally. Hindwings (Fig. 74): l/p: 2.71. Hypandrium (Fig. 77) of three sclerites, central sclerite with anterior margin strongly convex, laterally projected mesally. Phallosome with side struts slender, V-shaped anteriorly, fused basally; three pairs of endophallic sclerites, anterior pair Tshaped, with inner arms strongly curved on the inner side, close together in the middle, with abundant acuminate small teeth on the inner margin, apically with two to three more elongated (Fig. 78), outer arm laterally curved, projecting towards the posterior endophallic sclerite, this is wide, curved inward and with three apical acuminate processes inwardly directed, mesal arm elongated, laminar, widened and apically rounded; pair of mesal endophallic sclerites elbowed in the middle, basally truncate, almost touching in the middle; external parameres membranous, distally rounded, bearing pores, directed inward. Paraprocts oval, with medium, short sized setae and macrosetae on apical third, a macroseta with spatulate apex, other macrosetae near each sensory field, these with 18 trichobothria on basal rosettes (Fig. 76). Epiproct (Fig. 76) wide, triangular, rounded posteriorly, setae as illustrated.
