Pimelodus luciae is described from rio Itacaiunas, rio Tocantins basin. The new species exhibits a unique spotted pigmentation pattern for Pimelodidae. Pimelodus luciae differs further from remaining valid Pimelodus species by the following combination of characters: the relatively short distance between the posterior nostril and the anterior orbital border; dorsal surface of the supraoccipital process rounded; horizontal orbital diameter greater than interorbital distance; and distal portion of dorsal fin hyaline. Pimelodus luciae is known only from the type-locality.
