Figs 61–66 View Figure

Diagnosis. It is close to E. picta New & Thornton  , E. pictaoides García Aldrete  , E. caldasi  n. sp., and E. ecuatoriana  n. sp., from which it differs by the posterior processes of the central sclerite of the hypandrium and by the endophallic sclerites.

Color (in 80% ethanol). Head pattern ( Fig. 63 View Figure ). Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Labrum pale brown. Genae with transverse dark brown stripes. Antennae pale brown, distally cream. Maxillary palps brown, Mx4 distally dark brown. Tergal lobes of meso- and metathorax dark brown, with sides pale brown. Thoracic pleura dark brown, with white spots. Coxae pale brown. Forewings veins brown, with a dark brown spot at wing margin. Pterostigma dark brown ( Fig. 61 View Figure ). Hindwings hyaline, veins brown, with a brown spot at wing margin ( Fig. 62 View Figure ). Abdomen creamy, with dark brown subcuticular bands. Central sclerite of hypandrium pale brown, with median Y-shaped dark brown mark; postero-lateral processes ochre. Epiproct and paraprocts pale brown.

Morphology. Head ( Fig. 63 View Figure ): H/MxW: 1.48; compound eyes large, H/d: 3.75; H/D: 2.45; IO/MxW: 0.51. Outer cusp of lacinial tip broad, with six denticles. Mx4/Mx2: 2.27. Forewings ( Fig. 61 View Figure ): L/W: 2.35. Pterostigma: lp/wp: 3.19, areola postica tall, posteriorly slanted, side sclerites triangular, al/ah: 1.48. Hindwings ( Fig. 62 View Figure ): l/w: 2.56. Central sclerite of hypandrium slightly convex anteriorly, with a short and broad median arc flanked by two postero-lateral process; side sclerites triangular ( Fig. 66 View Figure ). Phallosome ( Fig. 65 View Figure ) anteriorly V-shaped, with slender side struts; external parameres membranous, distally broad and rounded, internally with a thin sclerotized band; two pairs of endophallic sclerites, antero-mesal endophallic pair with emarginated borders; mesal endophallic sclerite transverse, obtusely concave anteriorly, posterior borders denticulate on each side of median process ( Fig. 65 View Figure ). Paraprocts ( Fig. 64 View Figure ) almost elliptic, with a dense setal field distally; sensory fields with 28 trichobothria on basal rosettes. Epiproct ( Fig. 64 View Figure ) broad, semioval, rounded posteriorly, setal fields on sides and anteriorly and one large seta on each side.
