The ursine colobus (Colobus vellerosus, white-thighed colobus, Geoffroy's black-and-white colobus, white-thighed black-and-white colobus[2]) is a species of primate in the Cercopithecidae family. It is found in Benin, Ivory Coast, Ghana, Nigeria, and Togo, as well as very southernmost Burkina Faso.[3] Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.[2]
Nomenclature
Geoffroy's black-and-white colobus was formerly thought to be a variety of Colobus polykomos with which it interbred;[4] however, it has since been recognized as indeed a separate species.[5][6]

- ^ "Combining this information [on loud calls] with data on cranial morphology (e.g. Hull, 1979) and pelage (e.g. Rahm, 1970), Oates and Trocco, (1983) concluded that the bIack-and-white colobus monkeys are best regarded as belonging to five species: Colobus polykomos (Zimmerman, 1780); C. vellerosus (Geoffroy, 1831); C. guereza (Ruppell, 1835); C. satanas (Waterhouse, 1838); and C. angolensis (Sclater, 1860). Oates and Trocco (1983) also concluded that C. salanas retains more primitive features than other members of the group. and that C. guereza and C. vellerosus, in their low-frequency loud call and other features, are the most derived species." page 432 of Oates, John F.; Bocian, C.
