Etymology. In ancient Greek mythology, Britomartis is a goddess of mountains and hunting, who was primarily worshipped on the island of Crete.
Diagnosis. Forewing length is 20–21.5 mm in males and 25–25.5 mm in females. Cyana britomartis is a closest relative of C. divakara, from which it differs by its smaller black discal spots, broader subbasal white strip along the forewing costa, longer subbasal white spot along the anal forewing margin, and larger medial white spot. In addition, male of C. britomartis differs from that of C. divakara by its distal discal black spots well separated from each other. The male genital capsule of C. britomartis is very similar to that of C. divakara, but differs by its slightly narrower juxta, narrower valva with less curved costa, longer distal section of valva, and slightly more robust distal saccular process. The vesica of C. britomartis differs from that of C. divakara by its shorter but much broader dorsal subbasal diverticulum, larger cluster of spinules on the largest medial diverticulum, larger lateral cluster of spinules, and larger distal diverticulum. In the female genitalia, C. britomartis differs from C. divakara by its less sclerotized posterior section of the corpus bursae, and much smaller appendix bursae.
Distribution. The new species is known from North East India (Sikkim, Arunachal Pradesh and north of West Bengal), Nepal (Kishida 1994, as divakara) and China (Sichuan and Yunnan) (Fang 1992; 2000, as divakara).
