Diagnosis. This is a dark species with a forewing pattern as in E. pancoviana and the hindwing most similar to that of E. deinbolliana. It differs from these two species by the shape of the large, light patch extending to the dorsal margin in the anal area of the hindwing. The sclerite of segment 7 in the male differs from that of E. deinbolliana by its more subtriangular shape and rounded anterior margin (the margin is straight in E. deinbolliana).
Description. Male. Head. Frons whitish, vertex ocherous; labial palpus upturned, length approximately 1.2 times diameter of compound eye, third segment exposed, labial palpus and scape of antenna concolorous with vertex; antenna ringed brown and ocherous. Thorax. Nota and tegula with brown, yellow-tipped scales. Forewing (Fig. 18) length 4.0– 4.5 mm (n = 6); forewing costa weakly curved throughout, termen with shallow notch immediately below apex, rounded convex in remainder; upperside ground color dark brown, basal third mottled with paler scales; an irregular, dark brown, oblique line from basal 0.33 of hind margin bordering inner region; distal 0.66 of forewing with more complex pattern of irregular brown and leaden gray blotches, and orange striae; costal strigulae yellow and gray, divisions black or brown, some forming blackish dashes; speculum near mid-termen, with three distinct black dots, terminally bordered with leaden gray, ocherous line between this and terminal line; terminal line leaden gray. Fringe gray with yellow basal line which is interrupted in tornal area. Hindwing upperside mainly covered with brownish black scales; anal area with pale brownish gray scales from basal third to dorsal margin; line of black scales borders anal margin. Fringe whitish at anal corner becoming more grayish towards apex; cilia line brownish grey. Underside of fore- and hindwing pale brownish gray, with deep black scaling forming longitudinal patches. Anal lobe on upperside white with narrow, black proximal line; underside white, with black patch in distal half and black proximal margin. Hind tibia with pencil of pale brownish gray hair-scales. Abdomen. Black with pale brownish gray band at distal margin of each segment. Segment 7 (Fig. 29) with rounded subtriangular sclerite at mid-venter. Male genitalia (Fig. 22) with tegumen broad, rounded, laterally with sparse fine setae; valva with costa nearly straight in basal three fifths, distally upcurved; venter with curved concavity – depth of concavity depending on position under the cover glass; cucullus representing distal half of valva, rather broad, becoming slightly narrower distally, dorsal margin broad, unspined; caulis long, rodlike, attached to phallus subbasally; phallus with slight subdistal constriction, distally tapered, with pointed apex.
