The Semliki red colobus (Piliocolobus semlikiensis) is a type of red colobus monkey from central Africa. Historically it has been treated as a subspecies of the Central African red colobus (P. foai) but more recent taxonomies generally treat it as a separate species.[1] [2]
The Semliki red colobus lives in ironwood forest in the portion of the northeastern Democratic Republic of the Congo between the Semliki River valley and the Ruwenzori Mountains.[1] It may also live in a small area of Uganda.[2]
