Nacaduba is a genus of gossamer-winged butterflies (Lycaenidae). It constitutes many of the species commonly called "lineblues". As they are the genus initially erected to contain all lineblues, they might be considered the "typical" lineblues, as opposed to the species relatives now separated in Catapyrops, Prosotas and Petrelea.
