Patagioenas is a genus of New World pigeons whose distinctness from the genus Columba was long disputed but ultimately confirmed. It is basal to the Columba-Streptopelia radiation. Their ancestors diverged from that lineage probably over 8 million years ago. While the biogeographic pattern of this group suggests that the ancestors of the typical pigeons and turtle-doves settled the Old World from the Americas, Patagioenas may just as well be the offspring of Old World pigeons which only radiated into different genera later, given that the cuckoo-doves (Macropygia) of Southeast Asia seem also close relatives.
There are 17 species of Patagioenas, which can be assigned to 4 groups based on mtDNA , subunit I, and NADH dehydrogenase subunit 2, as well as the nuclear β-fibrinogen intron 7 data combined with analyses of vocalizations and morphology. They could be considered subgenera, but one of them remains unnamed as such and thus they are only informally listed here:
