Abstract


Three new species of bunodont otters are described from the Mio-Pliocene of East Africa. They are provisionally attributed to the genus Sivaonyx Pilgrim, 1931. The species described are Sivaonyx soriae, nov. sp. and Sivaonyx senutae nov. sp. from the Latest Miocene Lukeino Formation (Kenya) and Sivaonyx kamuhangirei nov. sp. from the Pliocene of Kazinga and Warwire (Uganda). Additional material of the species Sivaonyx ekecaman (Werdelin, 2003) is described from Sagatia, Mabaget Formation (Kenya). The systematics of the new tribe Enhydriodontini are discussed and we report the presence of evolutionary tendencies in the bunodont African otters: increase in body size, modification of the carnassial teeth. In particular in the P4/ the protocone becomes well separated from the paracone, at the same time that an anterior valley develops.
