Subspecies Ctenomys minutus subsp. minutus Nehring 1887

Subspecies Ctenomys minutus subsp. bicolor Ribeiro 1914

Distribution: Rio Grande do Sul, Santa Catarina, and Mato Grosso (S Brazil) and E Bolivia, but see Freitas (1995) who suggested that minutus is endemic to the Coastal Plains of S Brazil and that specimens described as minutus from Bolivia represent another species.

Discussion: Reviewed by Langguth and Abella (1970). Six subspecies were recognized by Contreras and Contreras (1984), however, no justification was given for the four new subspecies named in that paper. Altuna and Lessa (1985) and Altuna et al. (1985) regarded C. m. rionegrensis as a full species (see comments under rionegrensis ). Karyotype has 2n=42, 45-50 and FN=76 ( Freitas, 1997).
