Four species of coccidia are described which were found in Kobus defassa Rüppel, in the National Park Albert (Zaïre). These coccidia appear to be different from any of the coccidia so far described in African ruminants and seem to represent new species. For three of these the authors propose the names Eimeria kobi, E. congolensis and E. katangensis.

The fourth species is reported as Eimeria sp. because it was not possible to appreciate the morphology of the sporocysts completely.
