Euplocania garcialdretei n. sp.

( Figs 19–24 )

Diagnosis. Belonging in species group garcialdretei (new group). 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. Phallosome with lateral-anterior sclerite fused and forming an outwardly curved ring, centrally connected to the mesal sclerites.

Male. Color (in 80% ethanol). Body pale yellowish brown, with pigmented brown areas as indicated below. Head pattern ( Fig. 21 ), vertex cream, with central and lateral brown spots; front light brown, with brown spots, one of them in the form of an inverted T originating in the ocelli and from the internal 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 brown to cream, pronotum with brown spots; tergal lobes of meso- and metathorax brown, with cream spots, mesopleura brown, with small cream spot; metapleura cream, with brown spot. Legs: coxae dark brown, with little ochre spot, trochanters light brown with brown spot, 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. 19 ), 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. 20 ), hyaline, with veins brown and brown spots distally on veins R2+3, R4+5 and M. Abdomen pale brown to cream, with ochre subcuticular spots. Hypandrium and clunium brown, central sclerite with apical process light brown to cream; epiproct and paraprocts pale brown. Phallosome brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 21 ): H/MxW: 1.40; compound eyes large, H/D: 2.62; IO/MxW: 0.73. Outer cusp of lacinial tip broad, with five denticles; Mx4/Mx2: 1.29. Forewings ( Fig. 19 ): L/W: 2.43. Pterostigma: lp/wp: 3.98, areola postica high and wide with anterior edge rounded: al/ah: 1.48; M 4-branched, M4 distally forked. Hindwing ( Fig. 20 ): l/w: 2.73. Phallosome con side struts V-shaped, external parameres widened, unobservable pores, posterior margin rounded, with minute apical teeth; posteromesal endophallic sclerites widened basally, distally acuminate and curved inward ( Fig. 24 ). Epiproct semioval, anterior margin straight, anterolaterally concave, distally rounded, basal field with three central setae, two lateral macrosetae, apical setae as illustrated ( Fig. 22 ). Paraprocts ( Fig. 22 ) almost elliptic, with a dense setal field; sensory fields with 26 trichobothria on basal rosettes.

Measurements (in microns). FW: 3850; HW: 2650; F: 950; T: 1650; t1: 700; t2: 70; t3: 120; ctt1: 23; f1: 600; f2: 512.5; Mx4: 207; IO: 460; D: 336; d: 243; IO/d: 1.89; PO: 0.72.

Material studied. Holotype male. PERU. Cuzco. Kosñipata, Pillcopata, Sapam Sachayoc-Tunky Wasi , 13°02’20.0”S: 71°30’22.2”W, 1150m, 28-29.IX.2019. R. González and N. Carrejo. LED light trap in forest canopy . Paratypes: 3 males in ethanol, same data of the holotype .

Etymology. The specific epithet is also dedicated to Alfonso Neri García Aldrete (RIP), in recognition of his important contributions to the taxonomy of the neotropical psocids, as well as for his great human quality and teacher of young researchers.
