This black-and-white colobus occurs around Mount Kilimanjaro and Mount Meru. The catalogue uses species rank, while a 2015 field paper referred to it as the subspecies C. guereza caudatus.
Specimen and field descriptions record a black body with a long white shoulder mantle and a white tail; about 71–88% of the tail is white and it ends in a full tuft.
A short study of one group in Rau Forest Reserve, Tanzania, found that the monkeys spent 57.7% of observed time resting and 27.7% feeding.
