The white-legged duiker, Cephalophus crusalbum, was described from Gabon. It has been observed in central Gabon forest, including one record of a young animal eating fruit.
The 1994 Gabon account describes conspicuously white lower legs. It reports that the legs look like two white flashes as the animal runs through the forest.
In Forêt des Abeilles, central Gabon, a subadult was seen about 10 m from an observer, calmly chewing fruit of Klainedoxa gabonensis. The paper describes this as one observation lasting about 15 minutes.
An extinction-risk assessment has not been added yet.
