COMMENT: Includes Wilfredomys; see Hershkovitz, 1962, Fieldiana Zool., 46:21, Arata, 1967, in Anderson and Jones, p. 230, and Pine, 1980, Mammalia, 44: 195-202. Barlow, 1969, Life Sei. Contrib. R. Ontario Mus., 75:24-26, considered Wilfredomys a distinct genus. Includes Delomys; see Ellerman, 1941:366, and Cabrera, 1961:425; but also see Avila Pires, 1960, Boi. Mus. Nac. Rio de Janeiro, 220:1-6. Formerly included Rhipidomys macconnelli, Wiedomys pyrrhorhinos (see Hershkovitz, 1959, Proc. Biol. Soc. Wash., 72:5, 9), Aepeomys lugens, and A. fuscatus (see Gardner and Patton, 1976, Occas. Pap. Mus. Zool. Louisiana State Univ., 49:26, 32). Cabrera, 1961:431, and Walker et al., 1975:766, included Aepeomys in Thomasomys . This genus is in need of revision; its relationship to other thomasomyines needs clarification; see Hooper and Musser, 1964, Misc. Publ. Mus. Zool. Univ. Michigan, 123:21-22, Hershkovitz, 1966, Z. Saugetierk., 31: 125, and Cabrera, 1961:425. Reviewed, in part, by Carleton, 1973, Misc. Publ. Mus. Zool. Univ. Michigan, 146:1-43, Gardner and Patton, 1976:26, 32, and Voss and Linzey, 1981, Misc.
