Diagnosis. Forewing length is 14.5–15 mm in males and 18–18.5 mm in females. Cyana flavicincta  morphologically well differentiated from other Cyana  species. Externally it slightly resembles C. peregrina  , but differs clearly by its much larger size and larger black discal spots. In addition, the male of C. flavicincta  differs from that of C. peregrina  by the absence of an elliptical dark brown spot at hindwing costa, the discal black spots forming a more elongated triangle, the postmedial line perpendicular to the forewing costa (that is oblique in C. peregrina  ), the additional red stroke at costa situated in the medial area (whereas in C. peregrina  that is situated in the postmedial area). The male genital capsule of C. flavicincta  is similar to that of C. peregrina  , but the distal section of valva is slightly broader and the distal saccular process is slightly narrower. The vesica structure of C. flavicincta  is very different from that of C. peregrina  and most resembles those of not related C. puer  and C. neopuer  , but differs from them clearly by the presence of a hook-like curved ventral subbasal diverticulum, the presence of a cluster of very short spinules on the subbasal ventral diverticulum, and the absence of small medio-lateral diverticula bearing dense clusters of numerous short spinules (whereas in C. puer  and C. neopuer  there are two and one such diverticula respectively). The configuration of the female genitalia of C. flavicincta  also resembles those of C. puer  and C. neopuer  , but C. flavicincta  can be easily distinguished from them by its narrower ductus bursae, weakly sclerotized and rugose posterior section of the corpus bursae (similar to that of C. peregrina  ), and less elongate corpus bursae with a band-like signum (whereas in C. puer  and C. neopuer  corpus bursae is more elongate and bears two signa, round and elliptical ones).

Distribution. North East India (Assam, Meghalaya) ( Hampson 1903).
