It is endemic to Brazil, found in the southeastern Amazon and disjunctly in the Atlantic Forest between Rio Grande do Norte and Sergipe. Considerable taxonomic confusion has surrounded this species. Until 2001, most authorities included the Amazon black howler as a subspecies (or simply a taxonomically insignificant variation) of the red-handed howler, though its distinction had already been pointed out much earlier. The red-handed howler remained variable in ecology, colour and pattern of the fur, shape of the cranium, and

There are five subspecies of the "A. palliata" which are "Alouatta palliata aequatorialis", "Alouatta palliata coibensis", "Alouatta palliata palliata", "Alouatta palliata trabeata" and "Alouatta palliata mexicana". Compared with members of the howler monkey genus, the Mexican howler is sympatric with the Guatemalan black howler, "A. pigra", in Tabasco, Mexico. The Mexican howler differs from the golden-mantled howler, "A. palliata palliata", primarily in aspects of skull morphology, and in some differences in pelage. The golden-mantled howler's range includes parts of Guatemala and Honduras, and it is not clear if the
