This saki occurs in Amazonian forests of northeastern Peru. A taxonomic study described specimens from Peru's Río Javari-Mirim as reddish chestnut, while specimens from another area differed in color. At the Quebrada Blanco study site, sightings were more frequent in drier periods than during the rainy season.
The 2022 paper describes the Río Javari-Mirim series from Peru as reddish chestnut, with some dark-red or black hairs on the limbs and upper tail. Specimens from a different area were lighter reddish orange, showing variation among examined series.
Long-term records at Estación Biológica Quebrada Blanco in northeastern Peru show sightings were more common in drier parts of the year and rarer in the rainy season. The authors suggest movement between terra firme and floodplain forest, but did not directly track those long-distance movements.
