Three species of coccidia found in forest duikers (Cephalophus) in the forest of Ituri (Zaïre) are described. They do not appear to be identical with any of the coccidia already described in African ruminants and seem to represent new species for which the following names are proposed: Eimcria cephalophi (found in C. monticola), E. iturina (found in C. monticola), and E. turnbulli (found in C. dorsalis, C. monticola and C. nigrifrons). In addition this would be the first report of coccidia in the genus Cephalophus.
