Open encyclopedia reference
The Ugandan red colobus (Piliocolobus tephrosceles) or ashy red colobus is an endangered species of red colobus monkey, recognised as a distinct species since 2001. There is disagreement however over taxonomy with many considering the Ugandan red colobus to be a subspecies (Procolobus rufomitratus tephrosceles). The Ugandan red colobus is an Old World monkey which is found in five locations across Uganda and Tanzania.
