The Urubamba brown titi[1] (Plecturocebus urubambensis) is a species of Titi, a New World Monkey native to Peru.
- Populations of this species were previously classified under the brown Titi (Plecturocebus brunneus). Still, a 2015 study found it to be a separate, undescribed species that also belonged to a different species group from Plecturocebus than P. brunneus (the Plecturocebus donacophilus group) and therefore described it as P. urubambensis.
- Its appearance is very different from other titis, the whole body and tail are much darker, and the face is all black.
- This species is not as gray as brown titis and has a variable amount of black on the head. In addition, the species does not exhibit sexual dimorphism.
- The average body and head length of males are 31.1 centimeters (12.2 in), while that of females is 34 centimeters (13 in).
- Their fluffy tails are longer than the length of their head and body combined. It typically has thick fur with a back and limbs that vary in color from a tan or grayish agouti, with white ear tufts and a reddish underside.
