Description
Tab. 1. Cytogenetic data for Corydoras species from southern Brazil. 2n= diploid number; PR = Paraná State; SC = Santa Catarina State; RS = Rio Grande do Sul State; M = metacentric; SM = submetacentric; ST = subtelocentric; A = acrocentric; 18S = number of 18S rDNA sites; 5S = number of 5S rDNA sites; NOR = number of 18S rDNA sites detected by Ag-NOR staining. * The river was not identified in the original paper.
