(Figs 19–24)
Diagnosis. Belonging in species group cerata. It differs from E. cerata New, E. napensis n. sp., E. shuar n. sp. and E. teslai n. sp., by the shape of the central area of the hypandrium, with almost parallel straight sides and acuminate posterior processes, and by the shape of the anterior endophallic sclerites, that are distally dilated, with a long, slender, acuminate posterior process curved inward.

Color (of parts mounted on slide). Head (Fig. 21) pale brown, with pattern of dark spots like a mask in frons; clear, obtuse stripe between ventro-median border of compound eyes and dorso-lateral margin of clypeus; dark brown compounds eyes, ocelli hyaline, with ochre centripetal crescents; anteclypeus, clypeus and labrum dark brown; genae dark brown. Maxillary palps brown, Mx1 clearer. Legs: Coxae brown, with darker basal spot; fore- and mid- femora pale brown, with two brown spots; hind- femora dark brown, light brown apically; trochanters, tibiae and tarsi pale brown. Forewings (Fig. 19) hyaline, veins brown, with brown spots at veins ends; pterostigma with proximal and distal dark brown bands; cells cu1 and cu2 with dark brown spots. Hindwings (Fig. 20) hyaline, veins brown. Hypandrium brown. Epiproct and paraprocts light brown.
Morphology. Head: H/MxW: 3.36; compound eyes large, H/D: 2.7; IO/MxW: 0.20. Outer cusp of lacinial tips broad, with five-six denticles. Forewings: L/W: 2.76. Pterostigma: lp/wp: 1.5, areola postica low and wide, apex rounded: al/ah: 1.55. Hindwings: l/w: 2.83. Hypandrium (Fig. 24) of a single sclerite, anteriorly convex; median portion almost rectangular, sides with two mesal, short, acuminate processes, posterior border deeply concave; postero-lateral processes short, acuminate, each with a basal macroseta on the inner border. Phallosome (Fig. 23), side struts Y-shaped; external parameres distally quadrangular, with pores; five pairs of endophallic sclerites, anterior pair distally dilated, with a long, slender, acuminate posterior process curved inward, the ends converging mesally; antero-lateral pair posteriorly broad, with border straight, anterior processes acuminate and curved outward; mesal pair oval, close together, with small processes converging mesally; postero-lateral pair curved, C-shaped, distally pointed; posterior pair short, oriented longitudinally, distally acuminate. Paraprocts (Fig. 22) ovoid, with a dense field of setae on inner sub-apical area; sensory fields with 22 trichobothria on basal rosettes. Epiproct (Fig. 22) triangular, with two pairs of macrosetae, one lateral-median and other preapical, apical area with rows of small tubercles, basal field with abundant microsetae.
