The present study aimed to describe partial leucism, which is a pigmentation disorder, in two duiker species: Philantomba monticola and Sylvicapra grimmia. Leucism is a condition characterized by partial loss of pigmentation, resulting in white or pale patches on the animal's body. This is the first report of leucism in the subfamily Cephalophinae, which includes duikers, and similar occurrences may exist in other duiker species across their sub-Saharan distribution range. This finding highlights the potential for further research on pigmentation disorders in duikers and their prevalence in different species within the subfamily.
