Rumen ciliates of ten Tanzanian short horn zebu cattle were examined. A total of 15 genera and 46 species were identified, including a new Entodinium species. The ciliate density was 22.2×10⁴ ml⁻¹. The number of species per host and the diversity index showed high values, 33.8 and 2.80, respectively. Rumen ciliates had a low percentage composition of the genus Entodinium (7.0–25.0 % ) and a slightly higher percentage composition of the genera, Eudiplodinium (19.3 % ), Diplodinium (14.1 % ), and Ostracodinium (13.1 % ). Entodinium palmare n.sp., Eudiplodinium kenyensis, and Enoploplastron stokyi were found in all cattle examined. The former two species have been found only in African zebu cattle. Entodinium palmare n. sp. has a characteristic right surface of the body like the “palm of a hand” because of the concave part on the postero-dorsal part of the body, and has the same pattern of infraciliary bands as in other Entodinium species. Enoploplastron stokyi has a characteristic pattern of infraciliary bands analogous to those of Epidinium ecaudatum and Ostracodinium mammosum; with the right side of the adoral polybrachykinety gradually tapering and a slender short vestibular polybrachykinety.
