Etymology. In ancient Greek mythology, Chrysopeleia is one of Hamadryad nymphs.
Diagnosis. Forewing length is 13.5–14.5 mm in males and 16–16.5 mm in females. Cyana chrysopeleia is very similar to the closely related C. atlanteia and can be separated from it by the genitalia structures only. The new species differs from C. intercomma by its larger size, amber yellow forewing pattern (that is darker, apricot orange in C. intercomma), and pure white male hindwing (whereas in male of C. intercomma the hindwing is pale ginger orange). The male genitalia of C. chrysopeleia are most similar to those of C. atlanteia, but differ by their narrower uncus, slightly broader valva with a well-developed medial costal crest, the presence of a bunch of spinules on the medial diverticulum. The male genitalia of the new species differ from those of C. intercomma by the longer and basally narrower uncus, the aedeagus without subapical dentate ring, the vesica without spinules subbasally and distally, the presence of a bunch of spinules on the medial diverticulum, and the shorter dorsal diverticulum with a small subbasal subdiverticulum and slightly smaller spinules on its tip (whereas in C. intercomma the dorsal diverticulum is longer, with larger spinules on its tip, and has no subdiverticulum; the vesica has a subbasal bunch of spinules and a long distal cluster of spinules stretching from the medial part of vesica to the base of the vesica ejaculatorius; the medial diverticulum has no spinules). The female genitalia of C. chrysopeleia differ from those of C. intercomma by the narrower and less sclerotized ductus bursae, the less sclerotized posterior section of the corpus bursae with the shorter but more heavily sclerotized lateral protrusion, the much larger signum, the less sclerotized basal part of the appendix bursae, and the smaller membranous section of the appendix bursae.
Distribution. North and North East India (Uttarakhand, Assam, Arunachal Pradesh and Mizoram).
