Diagnosis. Externally the new species looks intermediate between E. variegata and E. ornata. It can be recognized by yellow-brownish grey wing color, more brownish than in E. variegata and E. ornata, more smooth, not angled antemedial line, dark medial shadow, expressed in costal field, less angled than in E. ornata reniform and wide rounded extension of subterminal line; the area restricted by submedial line and extension of postmedial line suffused with whish scales. Hindwing much darker than those in E. variegata and E. ornata, with pale subanal dash. By male genitalia it is closer to E. ornata, but differs by longer narrow vinculum, longer valva and long, pointed harpe. Aedeagus much longer and thinner than in E. variegata and E. ornata, vesica with two basal diverticula and subapical one. Female genitalia differ from E. ornata by small cup-like with medially cut antrum, long membranous ductus bursae and much smaller rounded corpus bursae.
Description. Adult (Figs. 7, 8). Wingspan: male 34–37 mm, female 39 mm. Head and thorax greyish-yellow; forewing color somewhat more greyish-brown than in E. variegata and E. ornata; wing pattern more developed than in E. variegata, but more smooth than in E. ornata. Basal line as small dot in costal area; subbasal line complete, diffused, shadowed with dark reddish-brown; antemedial line thin, brown curved basally on Cu-trunk; not joined with submedial line on anal margin as in E. ornata; orbicular distinct, elongate, formed by thin brown border like, shadowed by distinct medial shadow in costal area, joined with reniform by dark brown streak; medial shadow rather strong in costal area, traceable and diffused in medial field; reniform c-like, angled basally; postmedial line angled outward at vein M2, apical angle with oblique pale yellowish dash, contrasting with darker greyish-yellow costal area, followed from apex and surrounded with triangular brownish patch below; subterminal line, thin; sharply angled basally and strongly curved outward on veins Cu2-Cu3; veins in subterminal and terminal fields suffused with whitish; area between submarginal line and extension of subterminal line yellowish-grey, with reddish-brown dash and suffusion of whitish scales; terminal field pale brownish, with whitish veins and pale yellowish-grey subanal patch; cilia brownish, yellowish-white opposite veins. Hindwing yellowish-grey, darker than in E. variegata and E. ornata, with dark greyish suffusion in central part, yellowish costal and subanal parts. Cilia whitish-grey. Male genitalia (Fig. 17). Abdomen: coremata present as paired brush in the base and unpaired brush on 7th segment of abdomen. (Fig. 18). Tegument broad and high, shorter than vinculum; vinculum massive, narrow, much longer than in E. ornata; uncus curved basally, cylindrical, longer than in E. ornata, with minute apical hook; scaphium slightly sclerotised in basal half; juxta small, plate-like, transtilla broad, valva with parallel margins slightly extended apically and oblique-rounded apically; costa broad; sacculus as long as half of valva; harpe rather large, directed longitudinally, tapered and pointed apically. Aedeagus long, thinner and longer than in E. ornata, with sclerotised plate of carina; vesica moderate, with two subbasal diverticula, one of them armed with minute granulate cornuti, and with one subapical divertilum covered with minute granulation. Female genitalia (Fig. 24). Papillae anales quadrangular, apophyses anteriores and posteriores strong, almost equal in length, antrum small, cup-like, with triangular cut in middle; ductus bursae long, membranous; corpus bursae small rounded.
Etymology. The name refers to the more greyish forewing color, compared to E. variegata and E. ornata.
Distribution (Fig. 28). North Vietnam, Thailand, Malaysia. Moths collected in November and December.
