Ctenomys pearsoni Lessa and Langguth 1983 View in CoL

Ctenomys pearsoni Lessa and Langguth 1983 View in CoL , Com. Jour. Cienc. Nat. Montevideo ( Uruguay), 3: 86.

Type Locality: Uruguay, Dept. Colonia, 25 km SE of Carmelo, Arroyo Limetas.

Vernacular Names: Pearson's Tuco-tuco.

Distribution: Soriana, San José, and Colonia Depts. ( Uruguay).

Conservation: IUCN – Lower Risk (lc).

Discussion: Several karyotypes from different localities have been reported or associated with this taxon, including 2n=68-70, FN=80 ( Novello et al., 1990); 2n=70, FN=80 ( Kiblisky et al., 1977; associated with pearsoni by Lessa and Langguth, 1983); and 2n=56 and FN=77-79 ( Novello et al., 1990). Three different fundamental numbers have been reported for the 2n=70 karyotype (80 by Novello et al., 1990; 84 by Ortells et al., 1990; and 88 by Garcia et al., 2000). No karyotype can be associated with specimens from the type locality. The lack of G-band homology between the 2n=70 karyotype and the 2n=56 karyotype led Novello and Lessa (1986) to suggest that more than a single species was represented in C. pearsoni . Garcia et al. (2000) concluded that the 2n=70 karyotype of pearsoni was identical to the karyotype of dorbignyi and that there was no cytogenetic data for the regognition of dorbignyi .
