The Royal Antelopes ranges from south-western Guinea (the Kounounkan Massif perhaps representing the westerly known limit), Sierra Leone, Liberia, south-eastern Guinea, Côte d’Ivoire, to the Volta R., Ghana (Kingdon and Hoffmann in press). Records from the forests east of the Volta River in north-east Ghana remain questionable (Grubb et al. 1998). Fischer et al. (2002) reported what they considered to be reliable observations of the tracks of Royal Antelopes in Comoé N. P. in north-east Côte d’Ivoire.
