Loneura amankii sp. nov. Male

( Figs. 1-6 )

Diagnosis: Hypandrium with a posterior, broad median concavity, posterior processes short, distally acuminate, curved inward ( Fig. 5 ); lateral endophallic sclerites overlapping with the anterior sclerite, widened and mesally overlapping slightly between them; mesal sclerites fused, laminate and laterally widened ( Fig. 6 ). Forewings with submarginal brown band.

Color: Body brown. Head pattern ( Fig. 3 ), with an ochredark brown transverse band from the inner border of each compound eye to the ocellar triangle; another band from the inner border of each compound eye to the epistomal sulcus, connecting with the ocellar triangle. Vertex, occiput and post-occiput light brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Labrum, anteclypeus and postclypeus brown. Genae brown, with ochre spots; postgenae light brown. Antennae light brown; flagellomeres cream apically. Maxillary palps light brown to cream, Mx4 dark brown distally. Prothorax light brown. Tergal lobes of meso- and metathorax brown, with small light brown spots. Pleura brown to ochre, with cream areas. Legs light brown, tibiae and tarsi dark brown, coxae cream, with basal and apical brown spots; hind femora light brown, with dark brown spots. Wings almost hyaline, with small brown and greyish spots, veins dark brown. Forewings with a submarginal greyish band from R₄₊₅ to M₅; pterostigma hyaline, with small proximal and distal brown bands ( Fig. 1 ), with brown spots in base of wing, apical part of A1, veins Rs (basally) and transverse rs-m; veins with dark brown spots distally, at wing margin. Hindwings with brown spots distally on veins M at wing margin. Abdomen light brown, with ochre subcuticular spots. Clunium, epiproct and paraprocts light brown. Hypandrium brown to light brown; phallosome brown, endophallic sclerites dark brown.

Morphology: Head ( Fig. 3 ): H/MxW: 1.63; H/d: 2.37; IO/ MxW: 0.63. Vertex at the same level of the upper bor- der of the compound eyes. Outer cusp of lacinial tips broad, with six denticles. Mx₄/Mx₂: 1.14. Forewings ( Fig. 1 ): FW/W: 2.58. Pterostigma long: lp/wp: 5.08, areola postica rounded apically, almost twice as long as wide: al/ah: 1.87, R₄₊₅ sinuous, M four to five-branched, M₄ or M₅ forked. Hindwings ( Fig. 2 ): HW/w: 2.80; M threebranched, M₂ forked. Hypandrium ( Fig. 5 ) of a single sclerite, resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, with great median concavity distally, outer margins strongly convex, posterior lobes with short processes tapered apically, curved inward ( Fig. 5 ). Phallosome Y-shaped anteriorly, side struts slender,basally separated and articulated by a thin membrane; external parameres wide, with pores, no teeth on outer margin ( Fig. 6 ). Three pairs of endophallic sclerites, anterior pair overlapping with lateral endophallic sclerites forming wide sclerites, each with elongated lateral lobes, anterior margins with fine and short teeth, and with an elongated process curved outward, mesal sclerite laminar, anterior margin with wide concavity ( Fig. 6 ). Paraprocts ( Fig. 4 ) robust, oval, with setal fields and macrosetae as illustrated; sensory fields with 23-28 trichobothria on basal rosettes. Epiproct ( Fig. 4 ) semioval, with short setae and a field of microspicules and microsetae anteriorly.

Measurements (in microns): FW: 4950, HW: 3357, F: 1300, T: 2150, t1: 1010, t2: 82, t3: 170, ctt1: 30, f1: 930, f2: 920, f3: 740, f4: 605, f5: 400, Mx4: 312, IO: 420, D: 463, d: 320, IO/d: 1.31, PO: 0.69.

Material studied: Holotype male. Peru. Cuzco. Kosñipata, Pillcopata, Sapam Sachayoc-Tunky Wasi , 13°02′20.0″S: 71°30′22.2″W, 1,150 m, 25-26.IX.2019. N. Carrejo and R. González. LED light trap in forest canopy.

Etymology: This species is dedicated to Florencio Amanki, inhabitant and protector of a “paradise” in the Peruvian jungle (Sapam Sachayoc-Tunky Wasi).
