matschiei, occurs from western Kenya and Uganda south into northern Tanzania. Mt Uaraguess guereza or Percival's black-and-white colobus, C. g. percivali, found in the Matthews Range in Kenya. Eastern black-and-white colobus, C. g. kikuyuensis, occurs in Kenya on the Ngong Escarpment of Mount Kenya and in the Aberdare Range. Kilimanjaro guereza, C. g. caudatus, found in Tanzania and Kenya in the forests surrounding Mount Kilimanjaro and Mount Meru. The morphological difference between subspecies is most pronounced between the southeastern Kilimanjaro guereza, C. g. caudatus, and the northwestern western guereza, C. g. occidentalis. The intermediate subspecies show a gradual change between the two. Physical description The mantled guereza has a distinctive pelage, it is mostly black, with long white fringes of silky hair—known as a mantle or ornamentation—along the sides of its body and tail. The bands that make up the mantle start at the shoulders and extend along the back until they connect at the lower torso. The tail is long and ends in a white tuft which varies in how much it covers the tail. These features vary in color among subspecies, for example the tail of C. g. guereza is gray until the white tail tuft which covers half of its length, while the tail tuft of C. g. caudatus makes up 80% of the tail. The mantle color ranges from white to cream or yellow. Its face is framed by white hair and it has bushy cheek hairs. The thigh has a white stripe. Infants are born with pink skin and white hair. The hair and skin darken as they age and by three to four months they attain adult coloration. Male usually gain their coloration before females. The male typically weighs and the female weighs between . The head and body length averages for males and for females. Like most colobi, the mantled guereza has a small thumb that is vestigial. There is dentition sexual dimorphism among the subspecies. In some, the males have larger teeth than females, in others the reverse is true, and some have no significant difference. Distribution and habitat The mantled guereza is distributed throughout Equatorial Africa. It ranges from Nigeria and Cameroon in the west to Ethiopia, Kenya, Uganda, and northern Tanzania in the east. The mantled guereza lives in both deciduous and evergreen forests. It mainly inhabits forest and savannah woodlands and often extend into highland and montane forests. It
