Diagnosis. Belonging in species group patinoi ( González-Obando et al., 2018) , related to E. patinoi and E. rojasae , differing from it by the shape of the central sclerite of hypandrium and details of the general shape of the endophallic sclerites and by dark brown areas on sides of ocellar group, as illustrated. Female IX sternum broad, anterior margin with a deep concavity in the middle, laterally forming broadly rounded lobes, posterior margin bilobed ( Fig. 18 )

Male. Color (in 80% ethanol). Body pale yellowish brown, with pigmented brown areas as indicated below. Head pattern ( Fig. 9 ), vertex cream, with pale brown spots; front light brown, with dark brown spots; postclypeus brown, with ochre striae; genae ochre, with cream spot. Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents; labrum and anteclypeus dark brown. Maxillary palps: Mx1-3 light brown, Mx4 brown. Antennae pale brown, scape and pedicel brown, flagellomeres with apices cream. Thorax pale brown to cream, pronotum with brown spots; tergal lobes of meso- and metathorax with brown spots, mesopleura with large, dark brown spot. Legs: fore- coxae brown, with basal cream spot, mid- and hind- coxae cream, with little ochre spot, trochanters cream, femora medially and anteapically with brown spot, tibiae and tarsi pale brown, tarsi 1-2 darker. Forewings ( Fig. 7 ), hyaline, pterostigma with proximal and distal brown bands, a narrow pale brown band between R1 and R2+3 and forming an arc at the end of the cells from R4+5 to areola postica, and a large brown-yellowish area distally 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. 8 ), 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 and apically; epiproct and paraprocts pale brown. Phallosome brown.

Forewings ( Fig. 7 ): L/W: 2.63. Pterostigma: lp/wp: 4.26, areola postica high and wide with anterior edge rounded: al/ah: 1.39. M 4-branched, M4 distally forked. Hindwing ( Fig. 8 ): l/w: 3.07. Central sclerite of hypandrium almost as long as wide ( Fig. 11 ), setose as illustrated, distally with fine marginal teeth, apically with two closely spaced lobe-like processes located in a lower field; phallosome with side struts Y-shaped anteriorly, external parameres widened, with pores, posterior margin almost straight, with inner postero-lateral corners not projected ( Fig. 12 ); lateral endophallic sclerites strongly dilated, distally with broad teeth on its inner margin; pair of anterior endophallic sclerites transverse, curved inward connected apically to the lateral endophallic sclerites. Pair mesal endophallic sclerites elongate, separate, with mesal sclerite process enlarged distally, apically with short acuminate process on its outer side. Paraprocts ( Fig. 10 ) almost elliptic, with a dense setal field distally, as illustrated; sensory fields with 25 trichobothria on basal rosettes. Epiproct ( Fig. 10 ) trianguliform, anterior border somewhat convex, a group of three mesal setae near anterior border, a small setal field distally as illustrated.
