Remarks. 1. In the original description of Bizone Adita, Moore (1859) did not mention a number of specimens, therefore the existence of syntypes is possible. To avoid any confusion with the similar species C. signa , here we designate the female specimen deposited in NHMUK and labeled as “Type” as lectotype. 2. In the original description of Bizone bifasciata, Poujade (1886) cited three specimens of both sexes, which are syntypes. One of them (female) is labeled as lectotype (this designation is not valid as it is never published) and its photos are published in the MNHN website. In order to stabilize the nomenclature, here we designate this specimen as lectotype. 3. The type of Bizone walkeri Elwes is not found in the NHMUK collection. Here we follow Hampson (1900) and Strand (1922) and consider this taxon to be a synonym of C. adita .

Diagnosis. Forewing length is 16–18 mm in males and 20–21.5 mm in females. Cyana adita is very similar to C. signa , and can be distinguished by its separated distal discal spots and slightly more curved and wavy antemedial line (that is oblique and almost straight in C. signa ). The male genitalia of C. adita differ from those of C. signa by their slightly narrower uncus, larger lateral lobes of vinculum, slightly longer ampulla, longer distal lobe of subbasal diverticulum, shorter ventral lobe of subbasal diverticulum, and more robust spinules of the distal cluster. The female genitalia of C. adita differ from those of C. signa by the narrower ostium bursae, the shorter sclerotized area in the posterior section of corpus bursae, and the narrower appendix bursae.

Distribution. Pakistan (Azad Jammu & Kashmir) (present study), North and North East India (Himachal Pradesh, Uttarakhand, north of West Bengal, Sikkim, Assam, Meghalaya and Arunachal Pradesh) ( Hampson 1900; Strand 1922; Smetacek 2008; Singh et al. 2014), Nepal ( Kishida 1993; 1994), China (Shaanxi, Sichuan, Yunnan, Guangdong, Hubei, Fujian) ( Poujade 1886; Fang 2000; Dubatolov et al. 2012), North Thailand (Chiang Mai Prov.) and North Vietnam (Fan-si-pan Mts) ( Černý & Pinratana 2009).
