Abstract
A new genus of eomyid, Metanoiamys, is described from the Uintan of southern California. Two new species, M. agorus and M. marinus are also named. All Eocene species previously referred to “Namatomys” are included in Metanoiamys. Species of Metanoiamys increase in crown height and lophodonty of the cheek teeth through time, though no species lineages are recognizable. Metanoiamys represents the stem genus for the Namatomyini and possibly Eomyinae, but not for the entire Eomyidae.
