Etymology. In ancient Greek mythology, Dryope is the daughter of Dryops, king of Oeta, and mother of Amphissus by Apollo.

Remark. Cyana dryope is a member of the group of species including C. adita , C. signa , C. candida , C. trilobata and Nepalese C. lobbichleri (Daniel, 1961) . Species of the group have uniform genitalia and the diagnostic features can be found in the vinculum shape, the ampulla shape and the vesica diverticula configuration in males, and in the width of sclerotized section of corpus bursae and size of appendix bursae in females.

Diagnosis. Forewing length is 18.5–19 mm in males. Cyana dryope is similar externally to C. adita , but differs clearly by its broader forewing, larger black discal spots, antemedial line being strongly angled at costa and perpendicular to the anal wing margin (that is oblique in C. adita ), and strongly curved postmedial line. The male genitalia of C. dryope are similar to those of C. adita , but can be distinguished by the broader uncus, the U-shaped vinculum (in C. adita that has small lateral lobes), the narrower and less curved dorsal lobe of subbasal diverticulum, slightly smaller ventral lobe of subbasal diverticulum, and smaller spinules of the distal cluster.

The female is unknown.

Distribution. West Himalaya: North India (Himachal Pradesh) and West Nepal.
