The Itombwe black- forehead duiker ( Cephalophus hypoxanthus ) is a small antelope species from the tribe of the duiker (Cephalophini) within the family of horned bearers (Bovidae). It was described in 2001 by Peter Grubb and Colin Groves as a subspecies of the black forehead duckers ( Cephalophus nigrifrons ). After a revision of the ungulates in 2011 by Colin Groves, however, it is recognized as a separate species.
features
The Itombwe black forehead duiker reaches a head-torso length of approximately 85 to 95 cm, a tail length of approximately 11 to 15 cm and a weight of 13 to 16 kg. Overall, the fur is light yellowish to chestnut-colored, with the hair base tinted light gray. It is clearly brighter than that of the black-headed duck. The hair is long and relatively soft. There is no middle stripe on the back as in some other types of duiker, but the hair base is darker in color in this area. The legs are only slightly darker than the body. The front legs are tinted slightly gray-brown below the knee. On the hind legs, the tint is only barely visible on the thighs. The chin is white. Both sexes have horns. The tooth formula is I 0 / 3- C 0 / 1- P 3 / 3- M 3/3 (× 2), so a total of 32 teeth.

The distribution area extends to the Itombwe Mountains in the Democratic Republic of the Congo west of Lake Tanganyika . Its habitat are mountain forests.
Way of life
Nothing is known about his way of life. Like the black forehead duiker, it is probably diurnal and feeds on fruits and leaves.
