Aulacodes melanops Hampson, 1896 , Fauna Br. India (Moths), 4: 214. Type-locality: Sikkim.

Eoophyla melanops: Yoshiyasu, 1987 , Microlep. Thai., 1:163; Speidel & Mey, 1999a, Tijds. v. Ent., 142: 129; Li, You & Wang, 2003, Acta Zootaxonomica Sinica, 28(2): 299.

Diagnosis. The species is different by the forewing of male has the upper edge of cell diffused with fuscous long setae at basal half and androconial hairs covered with apical 2/3 of the cell from the upper edge. In male genitalia, it is special by three strong specialized setae about 2/3 length of valva, the third seta with minute spines laterally and a knife-shaped apex. In female genitalia, it is characteristic by its signa slender, about 5/6 length of corpus.

The species is very similar to E. halialis . It’s hard to distinguish them in external characters, except that the species has the androconial hairs obvious larger than E. halialis , and more or less yellower than the latter. In genitalia, the species has its uncus little slender than the latter in male and the signa slender than E. halialis in female.

Male genitalia ( Fig. 14 ). Uncus slender, apex pointed; gnathos about 3/4 length of uncus, with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, slightly constricted in base and apex, three strong specialized setae present at apex, about 2/3 length of valva, third seta with minute spines laterally and a knifeshaped apex; vinculum broad; saccus round; juxta plate-like, with apex slightly incurved; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 15 ). Anal papillae relatively broad, densely covered with setae; apophysis anterioris and posterioris near same length; antrum elongated, cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae about 1/3 length of corpus bursae, with many minute spines; a pair of slender singa present, about 5/6 length of corpus bursae, consisting of many minute spines.

Distribution. China (Gansu, Zhejiang, Hubei, Jiangxi, Hunan, Fujian, Guangxi, Guizhou), Thailand, India.

Remarks. A male specimen from Mt. Jiulian (Jiangxi) has the specilized setae basally kinked ( Fig. 15 ), rather than smoothed. By contrasting with other materials from Mt. Jiulian and other localities, we treated this material as a variation of E. melanops .
