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.
