Evaluator/s: Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Justification:
Listed as Least Concern as the species is thought to be common and there are no major threats to the species. However, given the impact of habitat loss within the range of the species, it is likely that the species is currently in decline.
