The genus Astyanax is a specious Neotropical fish group, occurring from the south area of the United States to Argentina. During the past few years, intensive studies on representatives of this group have been performed, broadening the genetic, taxonomic and biogeographical knowledge considerably. However, phylogenetic relationships among many species remain uncertain. Significant karyotypic variations occur in A. bimaculatus, A. scabripinnis and A. fasciatus, suggesting the existence of… CONTINUE READING
