Remarks. 1. Elwes (1890) described the species based on three syntypes, two males and one female. All three specimens are found in the NHMUK collection ( Figs 98–100 ). In order to stabilize the nomenclature, here we designate the male specimen labeled as “Type” as lectotype. 2. Notes on the taxonomy of the C. dohertyi species-group were published by Volynkin et al. (2017; 2019).

Diagnosis. Forewing length is 15–17 mm in males and 18–19 mm in females. Cyana dohertyi can be easily distinguished from other Indian species of Cyana by the combination of features such as amber yellow forewing pattern, three well-developed round black discal spots on forewing of both sexes, and the presence of a discal spot on hindwing (among Indian species the hindwing discal spot is present only in the C. divakara — C. britomartis species pair). The male genital capsule of C. dohertyi is similar to that of C. sikkimensis , but in C. dohertyi the valva is slightly narrower and the distal saccular process is longer. The vesica configuration of C. dohertyi is similar to that of C. sikkimensis , C. divakara and C. britomartis , but in C. dohertyi the largest medial diverticulum bears a long semilunar cluster of short spinules ringing it, whereas in C. sikkimensis , C. divakara and C. britomartis medial diverticulum bears one or two broad clusters of spinules. The female genitalia of C. dohertyi is most similar to that of C. sikkimensis , but differ by the much narrower posterior sclerotized section of the corpus bursae, the larger signum, and the shorter but broader basal sclerotized part of the appendix bursae.

Distribution. The nominate subspecies is distributed from Eastern Himalaya (North East India (Sikkim, north of West Bengal, Assam, Meghalaya, Nagaland, Arunachal Pradesh and Manipur) and Central and East Nepal ( Kishida 1993, as C. sikkimensis )) to the Chinese province of Yunnan ( Fang 1992; 2000). The populations from North Thailand (Chiang Mai Province) and North Vietnam (Fan-si-pan Mts.) belong to the subspecies C. d. mertsana Volynkin & Černý, 2019. The record for the Chinese province of Sichuan ( Daniel 1952) belongs to C. lada Volynkin, Černý & Saldaitis, 2019 (Volynkin et al. 2019). The record for the Chinese province of Shaanxi ( Daniel 1952) is doubtful and needs confirmation.
