DIVA ANALYSIS

Optimization of geographic distributions of taxa using dispersal/vicariance analysis ( Fig. 4 ) revealed the basal clade (constituted by O. microtis ) to be from the Amazonian, Cerrado, and Chaco ecoregions of South America. The next succesive basal clade, clade 1, is from the highlands of the Andes and Patagonia; clade 2 is from the Pacific Province ; clades 3, 4, and 5 are from the Cerrado; whereas clade 6 is from the Cerrado and Yungas (see Fig. 4 ) .
