Diagnosis. Forewing length is 14.5– 17 mm in males (15 mm in the holotype) and 19–20 mm in females. Cyana dohertyi mertsana ( Figs 21–24 ) differs from the nominate subspecies ( Figs 17–20 ) by its broader transverse lines of forewing. The male genitalia of the new subspecies ( Figs 35 ) are very similar to those of C. dohertyi dohertyi ( Figs 33, 34 ), but are characterized by the slightly broader sacculus with slightly more robust distal process, and the slightly longer band-like cluster of spinules on the largest diverticulum of vesica. Compared to those of the Chi- nese sister species C. ariadne ( Figs 15, 16 , 36 ), the male genitalia of C. dohertyi mertsana are characterized by the slightly broader sacculus with slightly more robust and short distal process, and the smaller spinules of the cluster on the largest diverticulum. The female genitalia of the new subspecies ( Fig. 44 ) have the slightly longer sclerotized posterior section of cospus bursae than those of C. dohertyi dohertyi ( Fig. 43 ), and the narrower sclerotized posterior section of corpus bursae, the smaller signum bursae, and the smaller appendix bursae than those of C. ariadne ( Fig. 45 ).

Distribution. North Thailand (provinces of Chiang Mai and Nan) and North Vietnam (Lao Cai Province). The nominate subspecies is distributed in Himalaya and Southwestern China (NW Yunnan).

Etymology. In the Slavic mythology, Mertsana is the heavenly Goddess, the ruler of the dawn and the patroness of a good and abundant harvest.
