The mantled guereza (Colobus guereza), also known simply as the guereza, historically the eastern black-and-white colobus, and Abyssinian black-and-white colobus, is a black-and-white colobus, a type of Old World monkey. It is native to much of west central and east Africa, including Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda and Chad. The species consists of several subspecies that differ in appearance. It has a distinctive appearance, which is alluded to in its name; the long white fringes of hair that run along each side of its black trunk are known as a mantle. Its face is framed with white hair and it has a large white tail tuft. The mantled guereza is diurnal and arboreal, found in both deciduous and evergreen forests. Wikipedia →
