aThe population more near the Andean region of Bolivia and Peru, e.g., the Austral Chaco region of Argentine, appeared very variable both in the number of C-banded autosomes and in the karyomorphs observed. By contrast, the samples farthest away from the Andean region, e.g., Brazilian Caatinga populations, were the most homogeneous, almost always exhibiting the same C-karyomorphs (BB BB AA).
