[1] Its fur is generally brown, with a lighter tail and chestnut-red undersides, neck and cheeks.

[1] Its body is approximately 35 cm long and its tail 61 cm, it weighs between 800 and 1400 g.[1] The species occurs between the Río Orteguaza and the Río Caquetá in the Colombian Department of Caquetá at altitudes between 190 and 260 m, but the exact distribution area is still unknown.

[5] Preliminary satellite analyses with Ladsat images show that from 1989 to 2002, 50 % of the primary forests in the species' range have been lost and the pasture areas have doubled.

[1] This is consistent with other titi monkey species, which form small, cohesive groups led by a bonded pair of adults.

[6] Like other titi monkey species, they are monogamous and pairs raise about one baby each year.
