It is this historical dimension that we shall examine next. Historical Zoogeography Early Pleistocene "Modern" voles, including Microtus in the broad sense of this volume, first appeared in the New World in the early Pleistocene (Irvingtonian—Martin, 1979; Repenning, 1980; Zakrzewski, this volume), about These first modern voles with root- less molars are placed in Allophaiomys {=Pitymys; see Zakrzewski, this volume), an extinct Holarctic genus thought by some to be ancestral either to modern Pitymys (van der Meulen, 1978; Za- krzewski, this volume) or to all later rootless cheektoothed voles (Chaline, 1974). According to Repenning (1980), these modern voles dispersed into the Nearctic from the Palearctic across the Bering.
