Discussion: Subgenus Reithrodontomys , megalotis species group. The standard and banded karyotypes depart markedly from other species of the megalotis group, and substantial variation in fundamental numbers has been reported among populations ( Bradley et al, 1988; Carleton and Myers, 1979; Engstrom et al., 1981; Robbins and Baker, 1980). Genetically strongly divergent from six other species of the subgenus Reithrodontomys based on cytochrome b sequences ( Bell et al., 2001). Whitaker and Hamilton (1998) regarded the subspecies virginianus and humulis as broadly intergrading and synonymized the former; L. Choate and Jones (1998) mentioned possible westward expansion of R. h. merriami in Oklahoma. See Stalling (1997, Mammalian Species, 565).
