A., 1974, in Webb, ed., Pleistocene Mammals of Florida, p. 60, and Chaline and Mein, 1979, for basis of allocation to Pitymys (Pedomys) . Van Der Meulen, 1978, Ann. Carnegie Mus., 47:101-145, regarded Pedomys as a subgenus of Microtus; Hall, 1981:812, placed this species in Microtus subgenus Pitymys . WDS recommended that, if Pitymys is considered a distinct genus, Pedomys should also be given generic status. Includes ludovicianus; see Raun and Laughlin, 1972, Southwest. Nat., 16:439. Includes minor, which Severinghaus, 1977, Proc. Biol. Soc. Wash., 90:49-54, listed as a distinct species without comment; but see Hall, 1981:8- 13.
