Diagnosis. Forewing length is 10.5–12 mm in males and 12.5–13 mm in females. Cyana guttifera is similar externally to C. moelleri and its allies, but can be distinguished by the pale ochreous hindwings of both sexes. The male genital capsule of C. guttifera is very different from that of C. moelleri and its allies by its V-shaped vinculum (that is U-shaped in C. moelleri ), longer transtilla, and valva being narrowed distally and having narrow and heavily sclerotized ventral medial lobe of costa (whereas in C. moelleri and its allies the valva is strongly broadened distally and the ventral medial lobe of costa is short, broad and more weakly sclerotized). The aedeagus of C. guttifera is shorter and broader than that of C. moelleri and its allies, and bears a V-like cluster of short spinules distally. The vesica of C. guttifera is broad and has two large diverticula, one of which bears a large and strongly dentate cornutus, whereas in C. moelleri and its allies vesica is smaller, has smaller diverticula and bears clusters of spinules. The female genitalia of C. guttifera differ clearly from those of other Indian congeners by the very broad and heavily sclerotized ductus bursae.

Distribution. South, North and North East India ( Hampson 1900; Smetacek 2008; Singh et al. 2014), Nepal ( Kishida 1993; 1994; 1998), Bhutan, China (Xizang, Yunnan, Guangxi, Hainan) ( Fang 2000), North and West Thailand ( Černý & Pinratana 2009), North Vietnam (de Joannis 1928).
