Implications phylogenetiques et biogeographiques des dernieres decouvertes de Muridae en Afghanistan,au Pakistan et en Ethiopie

Based on recent discoveries of Murid species in Pakistan and Afghanistan, two Asiatic autochtonous lineagesare proposed. Two forms from the African Pliocene seem to be related to these lineages. On this set of data, a new faunal province can be defined at the Mio-Pliocene boundary.
