Three new species of Coccidia (Apicomplexa: Eimeriidae) are described from rodents of the Ruwenzori Mountains, Uganda. Oocysts of n.sp., found in Thomas, 1888, are spindle-shaped, 19.6 (17.0-22.0) × 13.6 (12.5-15.0) µm, with a bilayered, moderately rough oocyst wall. An oocyst residuum is present. Sporocysts are ellipsoidal, with a flat Stieda body. Oocysts of n.sp. found in Thomas, 1906, are cylindrical and brownish, 26.9 (26.0-28.0) × 14.3 (12.0-15.0) µm; a polar granule is present and oocyst residuum absent. The oocyst wall is thick, unilayered, with a roughened surface. Sporocysts are broadly ellipsoidal and contain sporozoites with distinct refractile bodies. The oocysts of n.sp. were found in Thomas, 1906, and are ellipsoidal to cylindrical and unpigmented, 18.9 (18.0-20.0) × 10.8 (10.5-12.0) µm, with a smooth and unilayered oocyst wall. Sporocysts are broadly ellipsoidal with sporozoites with distinct refractile bodies. and represent the first coccidian species described from and .
