Euplocania matsiguenka n. sp.

( Figs 30–34 )

Diagnosis. Belonging in species group Enderleini, in the classification of Gonzalez-Obando et al. (2018). Due to the shape of the hypandrium and phallosome it is closely related to E. gallegoi , but unlike the latter it presents the hypandrium with four well-developed distal lobes (triconcave) and its posteromesal sclerite with two apical and outwardly curved teeth.

Male. Color (in 80% ethanol). Body pale yellowish brown, with pigmented brown areas as indicated below. Thorax pale brown to cream, pronotum brown; tergal lobes of meso- and metathorax with brown, mesopleura light brown, with brown and ochre spots. Legs: fore- coxae brown, with basal darker spot, mid- and hind- coxae cream, with basal brown spot, trochanters cream, femora cream medially and preapically with brown spot, tibiae and tarsi pale brown, tibia darker apically. Forewings ( Fig. 30 ), hyaline, pterostigma with proximal and apical brown bands, a narrow brown band between R1 and R2+3 and forming an arc at the end of the cells from R3 to areola postica, and a large brown area 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. 31 ), 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, central sclerite darker laterally, mesally and apically; epiproct and paraprocts light brown. Phallosome brown.

Morphology. As in diagnosis, plus the following: Head missing. Forewings ( Fig. 30 ): L/W: 2.49. Pterostigma: lp/wp: 3.75, areola postica high and wide with anterior edge rounded: al/ah: 1.41. M 4-branched, M4 distally forked, sometimes (forewing right) abnormally with M3 forked. Hindwing ( Fig. 31 ): l/w: 2.95. Hypandrium triconcave ( Fig. 33 ), each posterior lobe with rounded apex and with short acuminates processes, or small teeth directed posteriorly; central lobes wider than the lateral ones and with acuminate processes (teeth) more developed than those of the lateral lobes, setae as illustrated; phallosome with side struts Y-shaped, external parameres laminar, little sclerotized, wide and with small teeth at apical margin, pores unobservable ( Fig. 34 ). Three pairs of endophallic sclerites, the anterior pair transverse, small, connected to each lateral sclerite, the latter laminar, more widened medially, directed caudally; mesal sclerites proximally laminar, widened, with posterior endophallic sclerite elongated and surpassing the external parameres ( Fig. 34 ). Epiproct triangular, with two lateral macrosetae and few setae on basal field and posterior margin, as illustrated ( Fig. 32 ). Paraprocts ( Fig. 32 ) almost elliptic, with a dense setal field distally; sensory fields with 21 trichobothria on basal rosettes.

Measurements (in microns). FW: 3960; HW: 2800; F: 950; T: 1625; t1: 707.5; t2: 90; t3: 118; ctt1: 25

Material studied. Holotype male. PERU. Cuzco. Kosñipata, Pillcopata, Sapam Sachayoc-Tunky Wasi , 13°02’36.2”S: 71°30’15.7”W, 1100m, 25-26.IX.2019. N. Carrejo and R. González. LED light trap in forest canopy.

Etymology. The specific epithet is a noun in apposition, dedicated to the Matsiguenka, an indigenous people who live in the Amazon Basin regions from Peru, in Manú National Park.
