Remark. In order to stabilize the nomenclature, here we designate the male specimen from Khasi Hills deposited in NHMUK and labeled as “Type” as lectotype, and fix the species’ type locality as “Khásis”.

Diagnosis. Forewing length is 14–15 mm in males and 17–18 mm in females. Cyana watsoni  has no external differences from C. moelleri  and can be distinguished by the genitalia structures only. The male genitalia of C. watsoni  differ from those of C. moelleri  by their narrower aedeagus and the vesica structure: in C. watsoni  the vesica bears a long transverse band-like cluster of strong spine-like cornuti stretching from the base of the dorsal diverticulum to the vesica ejaculatorius, whereas in C. moelleri  there is a longitudinal band-like cluster of smaller spine-like cornuti stretching from the vesica base to the base of the distal diverticulum, and a subapical bunch consisting of 5–6 spine-like cornuti. The female genitalia of these species are very similar, but in C. watsoni  the ductus bursae is narrower than that of C. moelleri  , the posterior sclerotized section of corpus bursae is more rugose, and the signum is slightly smaller.

Distribution. North East India (Assam and Meghalaya) ( Hampson 1897; Hampson 1900, as part of C. molleri  , missp.), North Myanmar ( Černý & Pinratana 2009, as a part of C. molleri  , missp.) and China (Yunnan) (present study).
