Résumé
The Rhizomyinae is a subfamily of myomorph rodents within the family Spalacidae. It is subdivided into two tribes: the Asian Rhizomyini and the Tachyoryctini. Even though the origin of the Tachyoryctini is to be found in Asia, they are nowadays restricted to Africa. African Tachyoryctini are known from the Late Miocene and include a single genus with five species: the recently discovered Tachyoryctes makooka, which is described in detail in this work, T. pliocaenicus, T. konjiti and the two extant T. splendens and T. macrocephalus. Their closest Asian counterparts are the Late Miocene Protachyoryctes and Eicooryctes. A cladistic analysis involving all the above-mentioned taxa was carried out. Protachyoryctes tatroti turned out to
