Callicebus torquatus is not a white‐sand specialist

The hypothesis of Kinzey and Gentry [Primate Ecology: Problem Oriented Field Studies. New York, John Wiley & Sons, 1979] that Callicebus torquatus may be specialized for living in vegetation on white sand was evaluated by reviewing all observations I made of this species, where the substrate had been noted, and including some collection sites of J. Hernández Camacho. There was no evidence for the white-sand hypothesis. Instead, Callicebus torquatus was found to prefer upland and flooded forests that are tall and well stratified, and growing on many soil types, including white sand.
