52213A9D2A390D9B2B16D20C08D947CD.taxon	discussion	Discussion: Sometimes considered the most primitive group of South American hystricognaths with numerous fossil genera from Oligocene on, but Reig (1986: 418) reserved this distinction for the Echimyidae. Ctenomys is often placed here as a subfamily, and is closely related to octodontids (see comments under Ctenomyidae and in Cook et al. (1990: 22 - 23). Chromosomal variation is not as conservative as previously thought, 2 n = 38 - 102 and includes the only known mammalian tetraploid (Gallardo et al., 1999). Molecular data (Gallardo and Kirsch, 2000; Honeycutt et al., 2003) support the monophyly of the Octodontidae and the sister taxon relationship with the Ctenomyidae.	en	Wilson, Don E., Reeder, DeeAnn (2005): Order Rodentia - Family Octodontidae.

4F55D9B5FBDADC354F66F38FBBB8BFAE.taxon	discussion	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).	en	Wilson, Don E., Reeder, DeeAnn (2005): Order Rodentia - Family Octodontidae.

02905EFFA6682760DF0E553A4AFC9F92.taxon	discussion	Discussion: Waterhouse never designated a type specimen, which was finally designated by Thomas (1917 a). Waterhouse’s original type locality was " from Chile ", but in 1848 he added that the locality was from the Valle de las Cuevas near the Volcano of Peteroa, which would make the locality in Argentina (Pearson, 1984).

D8A606D64C48344FFA0422EFC2657EF2.taxon	discussion	Discussion: Considered a synonym of Octomys (see Reig, 1986: 408; Corbet and Hill, 1991: 204), but Cabrera (1961: 516) and Redford and Eisenberg (1992) considered it a separate genus based on very enlarged tympanic bullae. Octomys identified as sister taxon by molecular data (Gallardo and Kirsch, 2001; Honeycutt et al., 2003), however, Mares et al. (2000) suggested Pipanacoctomys and Salinoctomys are the sister taxa. Although demonstrated to be a tetraploid, its chromosomal evolution is more complicated than a simple duplication of the chromosomes of Octomys (Gallardo et al., 1999).	en	Wilson, Don E., Reeder, DeeAnn (2005): Order Rodentia - Family Octodontidae.
