Ctenomys perrensi Thomas 1898

Ctenomys perrensi Thomas 1898 , Ann. Mag. Nat. Hist., ser. 6, 18: 311.

Type Locality: Argentina, Corrientes Prov., Goya.

Vernacular Names: Goya Tuco-tuco.

Distribution: Central area of W Corrientes Prov. (NE Argentina).

Conservation: IUCN – Lower Risk (lc).

Discussion: See Contreras et al. (1985) for distribution. Specimens from the type locality have karyotypes of 2n=50, FN=84 ( Ortells et al., 1990). Specimens taken north of the type locality with FN=84 and 2n=53-56 or 58 were tentatively assigned to this taxon ( Ortells et al., 1990; Reig et al., 1992) but specimens from two other localities with FN=84 and 2n=62 were not included. Little or no genetic differentiation and no fixed differences of isozymes were observed among any of the populations with FN=84 from Corrientes Prov., suggesting that these populations are conspecific ( Ortells and Barrantes, 1994). Further, no fixed differences of isozymes were observed among perrensi , dorbignyi , and roigi ( Ortells and Barrantes, 1994) .
