The black-fronted duiker occurs from Cameroon to former Zaire , Rwanda and west Uganda , and southwards to north Angola . Its presence has also been confirmed from Mt. Elgon (across Uganda and Kenya ) and along the Aberdare range and Mt. Kenya in Kenya (Wilson & Reeder, 1993; East, 1996). A first rough map was acquired from Haltenorth & Diller (1980), then updated using specific country maps in East (1988, 1990) and according to Dr. R. East’s personal suggestions (23 June '97)
