Foa's red colobus

Foa's red colobus, Piliocolobus foai, also called the Central African red colobus, is a red colobus monkey known only from two widely separated parts of the Itombwe Mountains in the Democratic Republic of the Congo. It probably once ranged more widely across the Albertine Rift, but past deforestation is thought to have caused a major contraction. Several other red colobuses were once its subspecies and have since been raised to species: Lang's, Oustalet's, the Lomami, Tana River, Semliki and Ugandan red colobuses, and the Ulindi River red colobus. The highland form, now Piliocolobus foai in the strict sense, was long confused with a lowland form that is now a separate species. It has long red and black fur on the back and head and pale underparts, and its teeth are smaller than those of most red colobuses. Males have a body length of 50 to 69 cm and weigh 9 to 13 kg, and females weigh 7 to 9 kg. It is arboreal and diurnal and is often hunted for bushmeat.
