Discussion: Subgenus Reithrodontomys, megalotis species group. Reconstruction of historical biogeography based on mitochondrial DNA sequence data intimates that " sumichrasti " as defined by Hooper (1952) is a composite of two or more species (Sullivan et al., 2000), a finding that should be expanded within the context of a full revision. Sister species ( sensu lato) to the R. megalotis and R. zacatecae clade based on cytochromeb data (Bell et al., 2001).
