Descriptive notes. Head-body 40-62 cm, tail 55-85 cm; weight 8 kg (males) and 4-5—6-7 kg (females). The Southern Black Crested Mangabey is very similar to the Northern Black Crested Mangabey ( L. aterrimus ), but it is entirely black and has longer, laxer fur . Cheek whiskers are not sepiagray, as in the Northern Black Crested Mangabey, but black without a noticeable curve. Crown crest of the Southern Black Crested Mangabey is more flat and not pyramidal; it is also broader than in the Northern Black Crested Mangabey and slopes back and slightly up. Albinism has been reported in the Southern Black Crested Mangabey. Females are smaller than males.

Habitat. Primary and some secondary rainforest, and swamp and gallery forest.

Food and Feeding. Diets of Southern Black Crested Mangabeys are undoubtedly similar to other crested mangabeys and probably include seeds as a major component, along with fruits, young leaves, bark, flowers, and animal prey (invertebrates and small vertebrates).

Breeding. There is no specific information available for this species, but female Southern Black Crested Mangabeys exhibit a pink genital swelling when sexually receptive.
