Duiker

A duiker /ˈdaɪkər/ is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini. The tribe Cephalophini comprises three genera and 22 species, three of which are sometimes considered to be subspecies of the other species. The three genera include Cephalophus (15 species and three disputed taxa), Philantomba (three species), and Sylvicapra (one species). The subfamily was first described by British zoologist John Edward Gray in 1871 in Proceedings of the Zoological Society of London. The scientific name "Cephalophinae" probably comes from the combination of the New Latin word cephal, meaning head, and the Greek word lophos, meaning crest.
