We investigated the timing of origin and past connections between Andean and Atlantic Seasonally Dry Tropical Forests in South America based on the biogeographical history of Amorimia, a genus of Malpighiaceae restricted to South America. We used a time-calibrated phylogenetic tree based three cpDNA (ndhF, rpl16, and trnQ-rps16) and two nrDNA (ETS, and ITS) regions including all currently accepted species in Amorimia for ancestral area reconstructions. Our results show that: (1) the ancestor of Amorimia originated in Atlantic dry forests around 22.0 Mya; (2) ancestors of both Amorimia subgenera arose in Southern Brazilian dry forests from 18.0 to 14.0 Mya; (3) the remaining lineages in the genera diversified from Mid-Miocene to the late-Pliocene; and (4) a history of two expansion events during early and middle Miocene, besides several colonization events in different nuclei of dry forests in South America is suggested.
