Triplocania antisuyuensis n. sp. Male

( Figs 25–30 )

Diagnosis. Belonging in species group bifida of Subgroup MPB2A (see Classification below). Mesal endophallic sclerite large, transverse, anteriorly concave, posteriorly with a small concave process in the middle, and two small conic processes on the posterior border, between the apex and each end; anterior endophallic sclerites small, sausageshaped, with short spines on the surface; posterior endophallic sclerites medium sized, transverse, bearing three-five denticles along the outer border ( Fig. 30 ); central sclerite of hypandrium with a triangular posterior process; this species is close to T. triangularis Silva-Neto, García Aldrete & Rafael , from which it differs in having the median posterior process oft he central sclerite oft he hypandrium much narrower, in having the anterior endophallic sclerites more slender and papillose throughout, and in having small, lateral pointed processes in the posterior border oft he mesal endophallic sclerite, with the median posterior process distinctly narrower than in T. triangularis .

Color (in 80% ethanol). Body pale brown. Head pale brown, with pattern of small brown spots ( Fig. 27 ). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; scape light brown, darker basally, pedicel and f1–f5 light brown; Maxillary palps brown, Mx4 darker. Thorax pale brown. Tergal lobes of meso- and metathorax brown. Thoracic mesopleura pale brown, with cream spots. Coxae, trochanters and femora cream; tibiae pale brown, with distal ends darker; tarsomeres 1 light brown, tarsomeres 2–3 pale brown. Forewings with submarginal pale brown-yellowish band shaped like arches between the ends of the veins R1-CuA 1; a brown area almost triangular along CuA and end of CuP; a pale brown band along CuA 1; pterostigma almost hyaline throughout, a dark brown band distally; veins brown, with brown areolae at setal insertions and with dark brown spots at wing margin ( Fig. 25 ). Hindwings mostly hyaline, veins brown, with brown spots at ends of R and M veins ( Fig. 26 ). Abdomen cream with subcuticular ochre spots. Epiproct and paraprocts light brown. Sclerites of hypandrium pale brown, central sclerite with marginal areas darker. Endophallic sclerites dark brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 27 ): H/MxW: 1.48; H/D: 2.50; IO/MxW: 0.72. Vertex emarginate, slightly above the upper level of the compound eyes. Outer cusp of lacinial tips broad, with four wide denticles. Mx4/Mx2: 1.32. Forewings ( Fig. 25 ): L/W: 2.38. Pterostigma: lp/wp: 3.83. Areola postica triangular: la/ha: 2.10, CuA 1 gently concave distally; R 2+3 and R 4+5 longer than Rs after the transverse vein r-m. Hindwings ( Fig. 26 ): l/p: 2.65. Hypandrium of three sclerites, central sclerite convex anteriorly, lateral processes directed outward; median posterior process with sides converging to blunt apex ( Fig. 29 ). Phallosome ( Fig. 30 ); external parameres wide, with few pores, distally projected into a more sclerotized area, with few pointed teeth on outer margin. Paraprocts oval, with abundant medium and short sized setae and few macrosetae on apical third, a macroseta near each sensory field, these with 26 trichobothria on basal rosettes ( Fig. 28 ). Epiproct twide, anteriorly convex, posteriorly straight, setae as illustrated ( Fig. 28 ).

Material studied. Holotype male. PERU. Cuzco. Kosñipata, Pillcopata, Sapam Sachayoc-Tunky Wasi , 13°02’29.8” S: 71°30’22.2” W, 1200 m, 29.IX.2019. N. Carrejo and R. González. On moss on tree trunk. MUSENUV slide code 29933 . Paratypes: 1 male, same data as the holotype. MUSENUV slide code 29934 .

Etymology. The specific name refers to Antisuyu, in quechua, one of the four regions which formed the Inca Empire, the eastern region, which bordered with the Upper Amazon region.
