There are six recognized subspecies and one undescribed subspecies from the Mahale Mountains in Tanzania:[1] Like all black-and-white colobi, the Angola colobus has black fur and a black face, surrounded by long, white locks of hair.

There is a significant regional variation in the total amount of white on the body and the length of the fur.

The Angola colobus has a head-body length of 50 to 70 cm, with the males usually being larger than females.

The Angola colobus occurs in dense rainforests, both in the lowlands and coastal mountains.

The species can also be found in East Africa, especially in the interior and coastal forests of Kenya and Tanzania and in isolated mountain areas.
