Remark. In the original description, Moore (1877) mentioned two collections where the material is deposited therefore the existence of syntypes is obvious. In order to stabilize the nomenclature, we designate the male specimen deposited in NHMUK and labeled as ‘type’ as lectotype.

Diagnosis. Forewing length is 9–10 mm in males and 11 mm in females. Cyana amabilis   is a closest relative of C. quadrinotata   . Nevertheless, it mostly resembles externally C. pudens ( Walker, 1862)   ( Figs 66, 67 View FIGURES 52–67 , 173 View FIGURES 173–175 , 246 View FIGURES 246–251 ), but differs from it by the more elongate forewing, broader antemedial line, broader and almost straight postmedial line (in C. pudens   that is strongly curved at costa and anal forewing margin), and the not dentate inner margin of the subterminal line. In addition, in males of C. amabilis   the inner discal spot is larger, the outer discal spots are connected (those are well-separated in C. pudens   ), the subbasal line is broader and less curved, and the antemedial line is S-like curved (whereas in C. pudens   that is almost straight and only slightly curved at the wing costa). The male genital capsule of C. amabilis   differs from that of C. quadrinotata   by its larger lateral lobes of vinculum and slightly longer distal section of valva. The aedeagus of C. amabilis   is broader than that of C. quadrinotata   . The vesica of C. amabilis   differs from that of C. quadrinotata   by its dorsally broader dorsal diverticulum having short and narrow membranous subdiverticulum, broader ventral subbasal diverticulum, and its larger distal cluster of spinules. The female genitalia of the two species are very similar, but in C. amabilis   the laterally prominent sclerotized posterior section of corpus bursae is more rounded, whereas in C. quadrinotata   that is more trigonal.

Distribution. India: the Andaman and Nicobar Islands ( Arora 1983).
