( Figs. 7 , 19 , 30 )

Type material. China: Holotype: 3, Xiaoheishan (24°35ʹN, 98°41ʹE), Longling, Yunnan Province, 2300 m, 10.viii.2005, leg. Yingdang Ren (genitalia slide No. LWC06135). Paratypes: 11 3, 3 ƤƤ, same data as holotype (genitalia slide Nos. LWC06006, LWC06204, LWC08011, LWC08025, LWC08220); 1 3, Diancangshan (25°34ʹN, 100°13ʹE), Dali, Yunnan Province, 2990 m, 19–20.vii.1974, leg. Yao Zhou & Feng Yuan (genitalia slide No. LWC06297).

Diagnosis. This species is similar to E. angustea (Curtis, 1827) , but can be distinguished by the forewing densely covered with black scales, the postmedian line inconspicuously bending towards distal discoidal stigma and meeting dorsum by acute angle; and by the costa concave near base in the male genitalia. In E. angustea , the forewing is sparsely suffused with blackish brown scales, the postmedian line is acutely dentate towards distal discoidal stigma and meets dorsum perpendicularly; and the costa is straight in the male genitalia.

Description. Adult ( Fig. 7 ): Forewing length 7.5–8.0 mm. Frons pale brown. Vertex pale brown mixed with white. Labial palpus black; first segment white ventrally at base. Maxillary palpus black, apex white mixed with pale brown. Antenna with scapus blackish brown dorsally, white ventrally; flagellomeres blackish brown. Patagium blackish brown, white medially. Thorax white mixed with pale brown. Tegula black, posterior margin with long white scales. Forewing nearly parallel-sided towards blunt apex except narrowed basal part, covered with dense black scales; antemedian line white, broad, oblique outwards; antemedian stigmata black, stripelike, connected with antemedian line; distal discoidal stigma black, X-shaped, separated from black spot at costa; postmedian line white, much thinner than antemedian line, meeting costa perpendicularly, inconspicuously bending towards distal discoidal stigma, straight anteriorly, obliquely curved inward posteriorly, meeting dorsum by acute angle; subterminal line white, incurved at about posterior two fifths, where it meets postmedian line, together forming an X-shaped pattern; fringe white mixed with pale brown. Hindwing white, apex sparsely suffused with pale brown scales; fringe white. abdomen pale brown.

Male genitalia ( Fig. 19 ): Uncus ovate, notched at middle on posterior margin. Gnathos slender, as long as uncus, bluntly rounded apically. Valva narrowed near base, then broadened to rounded apex, slightly concave near base ventrally; costa concave subbasally. Juxta ovate. Phallus curved slightly, nearly as long as valva.

Female genitalia ( Fig. 30 ): Papilla anale ovate, notched posteriorly; about one fourth as long as apophysis posterior. Tergite eight one third length of apophysis anterior. Ostium bursae about twice as wide as colliculum. Antrum funnel-shaped, covered with dense granules; anterior one third as wide as colliculum, posterior two thirds broadened. Colliculum about one third length of ductus bursae, anteriorly covered with sparse tiny spines. Ductus bursae looped once anteriorly. Corpus bursae rounded, covered with dense tiny spines; signum oblong, placed at middle of corpus bursae; appendix bursae ovate, arising from anterolateral portion of corpus bursae.

Distribution. China (Yunnan).

Etymology. The specific name is derived from the Latin furvus = jet black, in reference to the parts of forewing densely covered with black scales.
