The head is small and round, the gray face is surrounded by a wreath of black hair. The ear tufts are colored white. The hind legs are extended as an adaptation to the jumping locomotion.

Distribution and habitat

Beni titi monkeys inhabit only a 400 km ² area in the southwest of the Bolivian department of Beni, where they live along the rivers and Yacuma Manique. Their habitat are gallery forests, they live below 400 meters above sea level.

Way of life

Little is known about the lifestyle of the Beni- titi monkeys. Presumably, they are like all titi monkeys diurnal and arboreal, moving on all fours, or jumping through the branches. Titi monkeys live in strictly monogamous family groups. These groups inhabit a fixed area, attention is drawn to the conspecifics morning duet songs. The diet should consist of fruits and small pieces of leaves and other plant material and possibly insects.

Endangering

Deforestation and possibly also the hunting are the major threats to the Beni titi monkeys. Due to these factors and the small distribution area, the IUCN lists the species as endangered ( endangered ).
