الملخص EN
The Astyanax scabripinnis complex is composed of a large number of almost morphological indistinguishable species, including Astyanax paranae and Astyanax rivularis, which exist in the Paraná and São Francisco Basins, respectively, and sometimes are considered subspecies of the A.
scabripinnis group or even are cited just as A.
scabripinnis.
The two river basins are separated by the Upper Paranaíba Arc, likely the main cause of the isolation of these species.
We used geometric morphometric tools and DNA analyses of populations of both species to identify the differences between them.
Geometric morphometrics separated the two species into distinct groups, whose main difference was the body depth.
This is generally related to the speed of the water flow in the river basins.
The maximum likelihood phylogram based on mitochondrial DNA sequences formed two main clades: one composed of the population of A.
rivularis and the other, of A.
paranae.
In the haplotype network, the species were similarly separated into two groups from the same ancestral haplotype, with A.
rivularis dispersing into two lineages in the São Francisco River Basin.
The distribution of A.
paranae is a consequence of a secondary dispersion event in the Paraná River Basin.
It forms two lineages from a haplotype derived from the ancestor.
The vicariant effect of separate basins, through the elevation of the Upper Paranaíba Arc, led to the allopatric speciation of the populations originating the present species.
The results of geometric morphometrics and molecular data of the fish show the importance of this geological event in the biogeography and evolutionary history of the ichthyofauna of the region and indicate that the isolation of these species seems to be effective.
