( Figs 2 View FIGURES 1–4 , 11 View FIGURES 10–15 )

Type material. CHINA, Shaanxi: Holotype ♂, Niutoudian (32.03ºN, 109.33ºE), Pingli , 772 m, 2.VIII.2016, leg. WX Feng & WT Shi, slide No. ZXJ20076. GoogleMaps

Diagnosis. The new species is similar to E. maculata Sattler, 1967 in forewing pattern. It can be distinguished by the black distal stripe of the forewing not connected with the distal stripe in the cell; by the uncus bifurcated in the distal 3/4, and the costa longer than half the length of the valva in the male genitalia. In E. maculata , the black distal stripe of the forewing is connected with the distal stripe in the cell; the uncus is bifurcated in the distal 2/3, and the costa is half the length of the valva ( Sattler 1967: 121, fig. 60).

Description. Adult ( Fig. 2 View FIGURES 1–4 ). Wingspan 27.5 mm.

Head: Vertex white with a black spot, frons white. Labial palpus white, black dorsally in basal palpomere and in basal half of second palpomere on outer surface; third palpomere black at base, in distal 2/5 on ventral surface, near apex on dorsal surface. Antenna with scape black on dorsal surface and along posterior margin, white on ventral surface and along anterior margin; flagellum greyish brown, white in basal 3/5 along anterior margin.

Thorax: Collar white, black basally. Mesonotum greyish white, with a black rounded spot anteromedially, with a pair of black spots medially and distally. Tegula greyish white, with black spot laterobasally. Forewing greyish white, black in basal 1/4 of costal margin; overlaid with 18 black markings: six black stripes in basal 3/5 below costal margin, the longest one extending from basal 1/3 transversely to distal 2/5 below costal margin, ovate silver grey spot laid between basal and second stripes, two short stripes in distal 2/5 below costal margin; cell with a short triangular black stripe beyond middle, with a black stripe at distal 1/3; distal stripe black, triangular, below its left placed a diffused spot; fold with black dot at base, rectangular stripe near base, with tadpole-shaped stripe near middle headed towards base, rounded black dot placed below its middle, narrow stripe above its middle; a black dot set near base above dorsum; ten marginal dots extending from distal part of costal margin along termen to tornus; fringe white basally, brown along middle of termen. Hindwing and fringe pale grey. Legs greyish white; coxa of foreleg with a black spot ventrally, femur and tibia black dorsally, tarsus black; femur of midleg mixed with black dorsally, with a black spot at base, tibia black dorsally, greyish white near base, at middle and at apex, tarsus black, greyish white at base of basal tarsomere and at apices of basal two tarsomeres; femur of hindleg mixed with yellowish brown dorsally, tibia with yellowish brown long hairs, tarsus mixed with black on inside, black at apical one tarsomere, black on outside, greyish white at apices of basal four tarsomeres.

Abdomen: Male genitalia ( Fig. 11 View FIGURES 10–15 ) with uncus quadrate in basal 1/4, asymmetrically bifurcate in distal 3/4, slender and bending sideways, pointed apically. Gnathos shorter than uncus; caudal part inconspicuous; oral part lip-shaped, with fine denticles on posterior margin. Labis short digitate, with dense setae. Valva with costa longer than half of its length, almost uniform in width, rounded apically; sacculus sub-quadrate, produced inward to a stout process basally, dorsal margin with a small digitate process near base, ventral half with dense long setae; cucullus sub-quadrate in basal half, digitate in distal half, covered with dense setae. Juxta widely banded, posterolateral lobes narrowed to slender apex. Phallus curved basally, with several unequal cornuti, apical one largest, drop-shaped.

Female unknown.

Distribution. China (Shaanxi).

Etymology. The specific epithet is derived from the Latin anomalus, referring to the uncus asymmetrically bifurcated in distal 3/4.
