Taxonomy
The blue-backed tanager was formally described in 1819 by the French ornithologist Louis Pierre Vieillot under the binomial name Pyranga cyanicterus. The type locality is Cayenne in French Guiana. This species is now the only member of the genus Cyanicterus that was introduced by Charles Lucien Bonaparte in 1850. The word cyanicterus  is formed from the Ancient Greek kuanos meaning "dark-blue" and ikteros meaning "jaundice-yellow". The blue-backed tanager is monotypic: no subspecies are recognised.
