The evolutionary and biogeographic history of West Indian boid snakes (Epicrates) was once thought to be well understood; however, new research including molecular studies has indicated that we are missing a clear understanding about the relationships of this group of nine species and 14 subspecies. Here, we present the first explicit set of molecular data-based analyses of the evolutionary relationships, divergence times, and historical biogeography of this group using a multilocus species-tree approach (10 genes and 6,256 bp). We find evidence for a single colonization of the Caribbean from mainland South America in the late Eocene/early Miocene, followed by a radiation throughout the Greater Antilles and Bahamas. Our results suggest some diversification within island banks, though most species divergence events seem to have occurred in allopatry. We also find evidence for a remarkable diversification within the Bahamian archipelago, and our data suggest that the recognition of another Bahamian endemic species is warranted. Furthermore, we find support for the previous suggestion that the genus Epicrates sensu lato Wagler is paraphyletic with respect to the anacondas (Eunectes Wagler), and hence we restrict Epicrates to the mainland clade and use the available name Chilabothrus Duméril and Bibron for the West Indian clade.
