Euplocania katarii n. sp.

( Figs 25–29 )

Diagnosis. Belonging in species garcialdretei group (new group). Closely related to E. garcialdretei , with somewhat similar hypandrium and wings, but unlike it the posterior process of the central area of hypandrium is shorter and without basal projection ( Fig. 28 ). On the other hand, the endophallic sclerites are different, with anterior pair of sclerites small and posteriorly acuminate; pair mesal sclerites elongated, fused to the lateral sclerites, with posteromesal sclerites distally acuminate and curved inward ( Fig. 29 ).

Male. Color (in 80% ethanol). Body pale yellowish brown, with pigmented brown areas as indicated below. Head pattern ( Fig. 27 ), vertex cream, with central and lateral brown spots; front light brown, with brown spots, one inverted T-shaped originating from the ocelli and from the inner margin of the compound eyes to the epistomal suture; postclypeus dark brown, with ochre striae; genae dark brown, with light brown spot. Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; labrum and anteclypeus dark brown. Maxillary palps: Mx1 light brown, Mx 3-4 brown. Antennae pale brown, scape brown, flagellomeres with apices cream. Thorax pale brown to cream, pronotum with brown spots; tergal lobes of meso- and metathorax brown, with pale brown spots, mesopleura pale brown, with sclerites or brown spot. Legs: coxae dark brown, trochanters light brown with pale brown spot basally, mid- and hind- femora dark brown, pale brown apically, forefemur light brown, with proximal and preapical brown spots, tibiae and tarsi pale brown. Forewings ( Fig. 25 ), hyaline, pterostigma with proximal and apical brown bands, hyaline basally; a brown spot preapically in cells cua and cup, as illustrated; brown areolae on veins in setal insertions, and brown spots distally on veins, at wing margin. Hindwings ( Fig. 26 ) hyaline, with veins brown and brown spots distally on veins R2+3, R4+5 and M. Abdomen pale brown to cream, with dark brown subcuticular spots. Hypandrium brown to pale brown, central sclerite with apical process light brown to cream. Phallosome brown to pale brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 27 ): H/MxW: 1.41; compound eyes large, H/D: 2.70; IO/MxW: 0.73. Outer cusp of lacinial tip broad, with six denticles; Mx4/Mx2: 1.17. Forewings ( Fig. 25 ): L/W: 2.48. Pterostigma: lp/wp: 4.27, areola postica high and wide with anterior edge rounded: al/ah: 1.42; M4 forked. Hindwing ( Fig. 26 ): l/w: 2.80. Hypandrium of a single sclerite, central area of the sclerite with deep V-shaped incision, each lobe formed with distal process, apically pointed, curved inward, forming concavity on its inner margin and basal projection with macrosetae ( Fig. 28 ). Phallosome con side struts U-shaped, external parameres widened, with pores, posterior margin rounded, with abundant small distal teeth ( Fig. 29 ).

Measurements (in microns). FW: 3850; HW: 2700; F: 950; T: 1600; t1: 725; t2: 75; t3: 125; ctt1: 24; f1: 635; f2: 537.5; f3: 480; Mx4: 240; IO: 460; D: 330; d: 235; IO/d: 1.96; PO: 0.71.

Material studied. Holotype male. PERU. Cuzco. Kosñipata, Pillcopata, Sapam Sachayoc-Tunky Wasi , 13°02’29.8”S: 71°30’21.8”W, 1100m, 28-29.IX.2019. N. Carrejo and R. González. LED light trap in forest canopy.

Etymology. The specific epithet is dedicated to Túpac Katari (Julián Apaza Nina), indigenous Aymara leader from Upper Peru (now Bolivia).
