Aconaemys Ameghino 1891, Rev. Argent. Hist. Nat., 1: 245.

Type Species: Schizodon fuscus Waterhouse 1842

Species and subspecies: 3 species:

Species Aconaemys fuscus (Waterhouse 1841)

Species Aconaemys sagei Pearson 1984

Discussion: Reig (1986:408) noted that Aconaemys is not separable from the Pliocene/Pleistocene form Pithanotomys Ameghino, 1887 at the generic level. If indeed the two are not separable, Pithanotomys would have priority as a name over Aconaemys . McKenna and Bell (1997) included in Pithanotomys . Aconaemys appears to by paraphyletic to Spalacopus (Gallardo and Kirsch, 2000; Honeycutt et al., 2003).
