Diagnosis. Forewing length is 20–21 mm in males and 24–25 mm in females. Cyana divakara is a closest relative of C. sikkimensis and C. britomartis It differs externally from C. sikkimensis by its very broad orange forewing pattern occupying the most of the forewing area, larger basal discal black spot, distal black spots fused to the comma-like dash, and the presence of a discal spot on hindwing. The male genitalia of C. divakara differ from those of C. sikkimensis by their broader juxta, slightly broader valva with stronger curved costa, narrower subbasal dorsal diverticulum, smaller cluster of spinules of the medial diverticulum, larger lateral cluster of spinules, and shorter and broader distal diverticulum. The female genitalia of C. divakara differ from those of C. sikkimensis by the narrower and less sclerotized posterior section of the corpus bursae with a sclerotized left lateral protrusion, the slightly larger signum, the less sclerotized basal section of the appendix bursae, and the broader distal membranous section of the appendix bursae. The differences between C. divakara and C. britomartis are listed in the diagnosis of the latter.

Distribution. North East India (Sikkim, north of West Bengal and Assam) ( Hampson 1900), Nepal and Bhutan (present study). The records for China ( Fang 1992; 2000) belong to C. britomartis .
