Triplocania tahuantisuyuensis n. sp.

(Figs 115–126)

Diagnosis. Belonging in a species group of its own, in Subgroup MPB2A (see Classification below), diagnosed as follows: Central sclerite of hypandrium with postero-lateral corners rounded, slightly projected postero-laterally. Two median processes long, narrowing distally, acuminate (Fig. 119). Phallosome (Fig. 120) with side struts slender, Y-shaped. Anterior endophallic sclerites of two pairs, the first pair wide proximally, narrowing distally, the second pair central, concave and wider distally; pair of lateral sclerites long, stout, asymmetric; mesal sclerite transverse, slender, broadly H-shaped, with arms short, stout. Postero-mesal endophallic sclerites elongate, with thick, acuminate apices. IX sternum subtrapezoidal, more enlarged anteriorly, anterior border weakly convex.

Male. Color (in 80% ethanol). Body brown, with cream and ochre spots. Head brown, with dark brown pattern (Fig. 117). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Maxillary palps pale brown, Mx4 darker. Antennae pale brown, flagellomeres with cream apices. Tergal lobes of meso- and metathorax brown; pleurae brown, with ochre spots. Legs pale brown, coxae, trochanters and femora light brown, coxae with dark spot proximally, femora with dark spots distally. Forewings with hyaline and light brown areas, a submarginal pigmented band from R 4+5 to CuA 1 (Fig. 115), pterostigma with brown bands proximally and distally, veins brown, with brown spots at veins ends. Hindwings hyaline, with grayish submarginal band, veins brown (Fig. 116). Abdomen cream, with widespread ochre areas; hypandrium, paraprocts and epiproct pale brown; endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head (Fig. 117): H/MxW: 1.52; H/D: 2.57; IO/MxW: 0.65. Vertex slightly emarginate, at the same level as the upper border of the compound eyes. Outer cusp of lacinial tips broad, with five denticles. Mx4/Mx2: 1.23. Forewings (Fig. 115): L/W: 2.56. Pterostigma: lp/wp: 5.25. Areola postica triangular: la/ha: 2.47, CuA 1 gently concave distally. Hindwings (Fig. 116): l/p: 2.94. Hypandrium (Fig. 119). Phallosome (Fig. 120). Paraprocts oval, with abundant medium and short sized setae on apical third, one macroseta with spatulate apex, others near sensory fields, these with 26 trichobothria on basal rosettes (Fig. 118). Epiproct (Fig. 118) broadly rounded posteriorly, setae as illustrated.
