Triplocania roesleri n. sp. Male

(Figs 109–114)

Diagnosis. It belongs in species group anchicayaensis, of Subgroup MPB2A (See Discussion below). It is related to T. panchei González-Obando, Carrejo & García Aldrete, differing from it in having the lateral posterior processes of the central sclerite of the hypandrium directed inward, not straight. The two species share having the external parameres broad, rounded distally. Endophallic sclerites distinct in both species. In T. roesleri, anterior endophallic sclerites long, almost rectangular, with an acuminate projection in the middle of the posterior border; lateral sclerites long, curved, rounded at both ends, mesal sclerite broadly H-shaped, with the anterior arms twice as long as the posterior arms, that are more robust; posterior sclerites long, with both ends acuminate, and a row of 3–5 short, curved, distally acuminate projections (compare Fig. 114 in this paper with Fig. 252 in González, Carrejo & García Aldrete 2017, to contrast the differences).

Color (in 80% ethanol). Body brown, with cream and ochre spots. Head pale brown, with dark brown pattern (Fig. 111). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Maxillary palps pale brown, Mx4 darker. Antennae missing. Tergal lobes of meso- and metathorax brown; pleurae pale brown, with small ochre spots. Legs pale brown, coxae, trochanters and femora with small dark spots. Wings hyaline, forewings (Fig. 109), pterostigma with small brown band distally, veins pale brown, with brown spots at the end of the R veins. Hindwings veins brown (Fig. 110). Abdomen cream, with ochre areas; hypandrium, paraprocts and epiproct pale brown; endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head (Fig. 111): H/MxW: 1.67; H/D: 2.25; IO/MxW: 0.55. Vertex slightly emarginate, slightly below the level of the upper border of the compound eyes. Outer cusp of lacinial tips broad, with five denticles. Mx4/Mx2: 1.32. Forewings (Fig. 109): L/W: 2.64. Pterostigma: lp/wp: 5.61. Areola postica triangular: la/ha: 2.10, CuA 1 straight distally. Hindwings (Fig. 110): l/p: 2.99. Hypandrium (Fig. 113) of three sclerites, central sclerite with anterior border convex, postero-lateral processes distally round, widely separated, converging to the middle. Phallosome (Fig. 114), side struts Y-shaped, separated. Paraprocts oval, with medium, short sized setae and macrosetae on apical third, with a macroseta near each sensory field, these with 23 trichobothria on basal rosettes (Fig. 112). Epiproct (Fig. 112) wide, broadly rounded posteriorly, setae and macrosetae as illustrated.
