Mono Patas del Dinde

This species has white hairs on upper lip hair which forms the shape of a handlebar moustache. This, when combined with the lack of the band between the ear and eye found in other members of Erythrocebus, distinguishes it from the rest of the genus.

This species is thought to be restricted to the area between the Nile and the western escarpment of the Great Rift Valley. It ranges from the vicinity of Metemma south to the Sudd. Although it is only known from Ethiopia and Sudan, it could potentially occur in South Sudan. In prehistoric times, this species may have had its range restricted to a montane refugium in western Ethiopia, through which it survived a period of aridification.
