Kais. Leop.-Carol. Akad. Wiss., 16(2):599 . REVIEWED BY: M. D. Carleton (MDC); A. Langguth (AL); M. A. Mares (MAM); R. A. Ojeda (RAO); O. A. Reig (OAR). COMMENT: Ellerman, 1941 , included in Akodon , as subgenera, the following genera named by Thomas: Thalpomys, Thaptomys , Bolomys, Chroeomys, Deltamys, Hypsimys , and also Abrothrix Waterhouse. Cabrera, 1961:457-458, followed Ellerman but also included Microxus as a subgenus and Chalcomys as a synonym of Akodon . Reig, 1978 , Publ. Mus . Munie. Cienc. Nat. Mar del Plata “Lorenzo Scaglia," 2(8): 164-190, included Abrothrix , Chroeomys, Deltamys, Hypsimys, and Thalpomys as subgenera and Chalcomys and Thaptomys as synonyms but considered Bolomys and Microxus distinct genera; this was a réévaluation of his views in Bianchi et al., 1971 , Evolution, 25:724-736, in which Abrothrix, Bolomys, Chroeomys, Hypsimys, Microxus, Thalpomys, and Thaptomys were considered distinct genera; also see Reig, 1980, J. Zool. Lond., 192:257-281. Corbet and Hill, 1980:150- 151 , followed Bianchi et al., 1971 , Evolution, 25:724-736. Massoia, 1964, Physis, ser. 24, 68:299-305, included Deltamys as a subgenus of Akodon; but also see Massoia, 1980, Hist. Nat., 1 (25): 179, who listed Deltamys as a distinct genus, but did not mention Reig, 1978:164- 190 , (followed here) who included it in Akodon as a subgenus. Thalpomys, based on T. lasiotis (which is a synonym of Bolomys lasiurus), is a subjective synonym of Bolomys; see Langguth, 1975 , Papeis Avulsos Zool. Sao Paulo , 29(8):45-54. Gardner and Patton, 1976 , Occas. Pap. Mus . Zool. La. St. Univ., 49:1 -48, listed Abrothrix as a distinct genus, following Bianchi et al., 1971 , Evolution, 25:724-736, but included it in the oxymycterine group following Hershkovitz, 1966, Z. Saugetierk., 31: 127. Arata, 1967, in Anderson and Jones, p. 229, included Microxus in Akodon; Hershkovitz, 1966, Z. Saugetierk., 31: 86, placed Microxus in Abrothrix as a synonym. Reig, 1978:164- 190 , and Reig, 1980, J. Zool. Lond., 192:257-281, are followed here (except Thalpomys is included in Bolomys). Formerly included arviculoides, tapirapoanus (which were included in species of Bolomys by Reig, 1978:167 ), and chacoensis (which was transferred to Bibimys by Massoia, 1980, Ameghiniana, 17: 280-287). This genus is in need of revision. Subfamily Hesperomyinae ; see comment under Cricetidae . ISIS NUMBER: 5301410008001000000.
