This red colobus was historically recorded in forests of eastern Côte d’Ivoire and western Ghana. Adults have a glossy black crown, back and tail, with maroon forehead, limbs, lower flanks and underparts. It is active by day in the upper canopy. The 2021 IUCN conservation plan lists it as Critically Endangered and reports no confirmed sightings of living individuals in surveys from 1993 onward.
Adults have a glossy black crown, nape, shoulders, back, and tail. The forehead, limbs, whiskers, lower half of the flanks, and underside are bright maroon. The backs of the thighs and male scrotum are white; the face is slate blue, the lips are pink, and the nose is flat. Head-and-body length is 45–67 cm in males and 42–56 cm in females; tail length is 56–68 cm in males and 52–67 cm in females. Body mass is reported as 5.5–6.3 kg.
It inhabits moist forest, including some semi-deciduous forest with a marked dry season. Where it occurs with King Colobus, it uses higher levels of the forest canopy. It is diurnal and arboreal. A short study at Bia National Park, Ghana, in the 1970s recorded groups of 34 and 58 animals, with home ranges of 140 ha and 100 ha, respectively.
