COMMENT: Includes Macruroryzomys, Melanomys, Micronectomys, Mieroryzomys, Oligoryzomys , and Sigmodontomys; see Gardner and Patton, 1976, Occas. Pap. Mus. Zool. La. St. Univ., 49:1 -48, who considered Oecomys a distinct genus, as does RAO; but also see Hershkovitz, 1960, Proc. U.S. Nat. Mus., 110(3420):515-532, Husson, 1978:402, Hall, 1981: 618, and Voss and Linzey, 1981, Misc. Publ. Mus. Zool. Univ. Mich., 159:13, who considered Oecomys a subgenus of Oryzomys . Ellerman, 1941: 340, included Oligoryzomys in Oryzomys as a subgenus; Cabrera, 1961:380, included Oligoryzomys in subgenus Oryzomys as a synonym. Gardner and Patton, 1976, Occas. Pap. Mus. Zool. La. St. Univ., 49:2, included Macruroryzomys and Micronectomys in Oryzomys; these names were proposed as subgenera by Hershkovitz, 1948, Proc. U.S. Nat. Mus., 98(3221):49-56, but Hershkovitz, 1970, J. Mammal., 51: 791, and Pine and Wetzel, 1975, Mammalia, 39:653, considered Macruroryzomys and Micronectomys, nomina nuda. Walker et al., 1975:759, considered Melanomys a distinct genus. Formerly included Nesoryzomys (see Gardner and Patton, 1976:20, and Voss and Linzey, 1981, Misc. Publ. Mus. Zool. Univ. Mich., 159:24), borreroi (which Gardner and Patton, 1976:41, transferred to Zygodontomys), Wiedomys pyrrhorhinos (see Hershkovitz, 1959, Proc. Biol. Soc. Wash., 72:5), Pseudoryzomys wavrini (see Hershkovitz, 1962, Fieldiana ZooL, 46:208), Rhipidomys maculipes (see Hershkovitz, 1960, Proc. U.S. Nat. Mus., 110:519), and simplex (which Massoia, 1980, Ameghiniana, 17: 280- 287, transferred to Pseudoryzomys). North American species revised by Goldman, 1918, N. Am. Fauna, 43:1 -100. Oryzomys is in need of revision. Subfamily Hesperomyinae; see comment under Cricetidae.
