The colors indicate the different hydrographic basins in Brazil listed in the legend and the colored circles indicate the collection sites, with the corresponding karyomorphs found as: A blue, B pink, C yellow, D red, F green, and G black. The ellipse indicates a site with sympatry for both karyomorphs A and D. The ideograms on the right represent partial karyotypes of each karyomorph and their sex chromosomes. Pairs of karyomorphs with homologous sex chromosomes are boxed (see the text). Karyomorphs C and D differ from A and B by micro-rearrangements, though the details are not yet fully clear.
