title: [Comparative cytotaxonomy of 3 species of Cichlasoma (Pisces: Cichlidae) native of Costa Rica].
abstract: The karyotype of three species of Cichlasoma: C. dovii, C. managuense and C. friedrichstali were studied. The number of diploid chromosomes is 2n = 48 in the first two species. Their karyotypes are composed of four pairs of meta-submetacentric chromosomes. The arms fundamental number (NF) is 56. C. friedrichstali has three pairs of meta-submetacentric chromosomes and 21 pairs of subtelocentric-telocentric chromosomes. This species presents two different diploid numbers, 2n = 48 and 2n = 47.
