Abstrakt: We examined the role of geographic barriers and historical processes on the diversification of Apogon species within the tropical eastern Pacific (TEP). Mitochondrial and nuclear DNA sequences were used in Bayesian and Maximum likelihood analyses to generate a phylogenetic hypothesis for Apogon species. Bayesian inferences were used to date the cladogenetic events. Analyses with BioGeoBEARS were conducted to reconstruct the biogeographic history and ancestral ranges. The phylogenetic results show a monophyletic clade of TEP Apogon species with A. imberbis from the eastern Atlantic as sister species. The two lineages diverged during the Miocene. Within the TEP clade, two subclades diverged at around 11.1 million years ago (Mya): one clusters the coastal continental species (A. pacificus, A. retrosella and A. dovii), and the second clusters the oceanic island species (A. atradorsatus, A. atricaudus and A. guadalupensis). The estimated diversification times of these subclades were 9.8 and 7.1 Mya, respectively. Within each subclade, species divergences occurred during the Pliocene-Pleistocene epochs. The divergent event between the Atlantic A. imberbis and Apogon TEP clade corresponds to the first closure event of the Central American Seaway. The biogeographic history of Apogon within the TEP appears to be the result of vicariant, dispersal and founder events that occurred during the last 11 million years. The vicariant and dispersal events occurred along the mainland and were associated with the origin of the Central American Gap. The founder events could have allowed the invasion of Apogon to TEP island areas and could have been driven by ancient warming oceanic waters, changes in circulation of marine currents, and the presence of seamounts in ancient marine ridges that allowed the settlement of marine biota. These factors may have allowed Apogon lineages to cross the TEP biogeographic barriers at different times, with subsequent genetic isolation.
