Diagnosis. In facies, E. hymenosa is similar to E. lecaniodiscana with the forewing rather cream and pale brown in the basal half and darker brown in distal half ( Fig. 17 ). Because E. hymenosa is known only from the female, male secondary features, which are usually diagnostic for members of this group, are unknown. Nonetheless, E. hymenosa can be distinguished by the presence of a pair of weak patches posterad of the sterigma, and a much narrower and shallower pocket of the sterigma.

Redescription. Male. Unknown. Female. Head. Vertex and frons pale orange-yellow, sprinkled with brownish gray [now lacking, details from Razowski 2013]. Thorax. Nota pale orange yellow, sprinkled with brownish grey. Forewing ( Fig. 17 ) length 7.0 mm (n = 1); forewing broad, expanding to middle; costa convex; termen weakly concave beneath apex, broadly convex otherwise; upperside ground color orange yellow, sprinkled and strigulated greyish brown; some longitudinal strigulae at middle of wing; costal strigulae cream, slender, subapical strigula broad, paler, divisions brownish; dorsal patch slightly paler than remainder of wing, with brownish lines; tornal area brown; small blotch at mid-termen; speculum orange-yellow with three brown strigulae. Fringe brownish, orange-yellow at apex. Hindwing uniformly brown. Fringe white-cream with brown basal line. Abdomen. Genitalia ( Fig. 46 ) with papillae anales and apophyses as described for genus; sterigma membranous with a pair of weakly spined patches in posterior part, comprised of thick membrane, antrum of similar composition; ductus bursae long, slender; corpus bursae ovoid with a pair of thorn-shaped signa.

DNA barcodes. There are no sequence data available for this species.

Type. Holotype ♀, Nigeria, [Oyo State], Ibadan, [International Institute of Tropical Agriculture], Golf Course Lake , 6–10 Feb 1978, D. & M. Davis, USNM slide 143,024 ( USNM).

Distribution and biology. The life history is unknown, but based on related species, it is likely that the larvae of E. hymenosa feed in the fruit of Sapindaceae .
