A cytogenetic chromosome study was carried out on specimens of four species of Ctenomys-C. talarum, C. rionegrensis, C. pearsoni and C. dorbignyi-from 10 different populations. The analysis of chromosomes was performed through sequential uniform stain, G and C-banding, and with restriction enzymes. The results obtained are discussed in relation to phylogeny. Chromosome evolution in the species studied suggests that the chromosome number has increased due to fissions, and that a reduction of the amount of constitutive heterochromatin has occurred. Different types of heterochromatin, with different patterns, have been added in parallel during evolution. Some taxonomic suggestions can be deduced from this cytogenetic study.
