Abstract:A new species of microtine, Pliophenacomys finneyi, is named on the basis of smaller crown height and shorter dentine tracts from the Fox Canyon local fauna of late Pliocene age. Pliophenacomys finneyi is considered to be ancestral to P. primaevus, which has a higher crown height and dentine tracts and is found in stratigraphically younger local faunas in the Great Plains area. We suggest that the absence of Pliophenacomys from the type locality of the Rexroad local fauna is due to its ecological replacement by the genus Sigmodon.
