Diagnosis. The species is diagnosed by the androconial hairs in male covered with the whole cell from the upper edge and the hindwing with a dark fusoucs area above the submarginal band. In male genitalia, it is special by the three strong specialized setae present at apex, about half length of valva, third seta with minute spines laterally and a knife-shaped apex. In female genitalia, it is special by the ductus bursae about the same length of corpus bursae, and corpus bursae with a pair of broad signa, little shorter than corpus bursae.

The species is very closed to E. inouei Yoshiyasu, 1979 . Both species can be easily distinguished from other species by their hindwing have the area between postmedial band and submarginal band suffused with dark scales. However, E. conjunctalis is different from E. inouei Yoshiyasu, 1979 by the latter species with more fuscous gound color on both wings and 3 smaller marginal spots at the underside of hindwing, constrasting with 4 spots in E. conjunctalis ( Yoshiyasu, 1979, 1985).

Male genitalia ( Fig. 10 ). Uncus with base broad; gnathos about 2/3 length of uncus, apex with several dorsal teetn; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, wided from base to apex, apex truncated, three strong specialized setae present at apex, about half length of valva, third seta with minute spines laterally and a knifeshaped apex; vinculum broad; saccus round; juxta plate-like, with apex bifid; aedeagus slender, veisica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 11 ). Anal papillae relatively narrow, densely covered with setae; apophysis anterioris and posterioris near same length; antrum relatively short; collar sclerotized; ductus seminalis arising below collar; ductus bursae elongated, as long as corpus bursae, with many minute spines; a pair of signa present, little shorter than corpus bursae, and consisting of many minute spines, with base half thin and terminal half broad.
