Resumen

The saki monkeys, genus Pithecia Desmarest, 1804, have undergone drastic taxonomic changes in a 2014 revision of the genus. In that revision, Pithecia hirsuta Spix, 1823, and Pithecia inusta Spix, 1823 were considered as valid species, although both have been widely considered synonymous with Pithecia monachus (E . Geoffroy Saint-Hilaire, 1812). Nonetheless, by reviewing the original descriptions of both species, we argue that inusta cannot be applied to the Peruvian populations of Pithecia inhabiting the Ucayali River watershed since the type locality is in a distinct geographic region from the species' distribution, as outlined in the 2014 revision. In fact, the area falls completely outside the expedition's itinerary that collected the holotype. Thus, to preserve stability until further evidence is furnished, the abovementioned Pithecia populations should be regarded as P. monachus.
