Habromys (Hooper and Musser, 1964) . Occas. Pap. Mus. Zool., Univ. Michigan, 635:12.

TYPE SPECIES: Peromyscus lepturus Merriam, 1898 .

COMMENTS: Peromyscine. Circumscribes species originally placed with the Peromyscus mexicanus complex, subgenus Peromyscus (Osgood, 1909) . Hooper and Musser (1964b) acknowledged their distinctive morphology as the subgenus Habromys of Peromyscus (and Hooper, 1968b), a clade which Carleton (1980) viewed at the generic level. Systematic evidence weakly supports common ancestry of Habromys with Neotomodon and/ or Podomys (Carleton, 1980; Hooper and Musser, 1964b; Stangl and Baker, 1984b). Male reproductive tract examined by Hooper (1958), Hooper and Musser (1964b), and Linzey and Layne (1969, 1974).
