A Proposal For The Common Names For Species Of Chiropotes (Pitheciinae: Primates)

The common English name for the genus Chiropotes is currently bearded saki. We propose the use of "cuxiu" as the common name for Chiropotes species, arguing that this term not only has deeper cultural and historical roots, but would mesh with the common name currently in use over the vast majority of the genus range. Cuxiu (pronounced "coosh-e-oo") would be phylogenetically and taxonomically more appropriate, and less ambiguous, than the currently used term, and remove the implied close affiliation between Pithecia and Chiropotes. Finally, as an indigenously-derived name, it would fit with the common names in use for the other two genera in the sub-family Pitheciinae (uacari, Cacajao; saki, Pithecia), both of which also have indigenous origins.
