Several studies attempting to explain Calisto diversity gave different weights to vicariance, dispersal and adaptive radiation. We utilized molecular phylogenetic approaches and secondary calibrations points to estimate lineage ages. We used the dispersal-extinction-cladogenesis model and the Caribbean paleogeographical information to reconstruct ancestral geographical distributions. We also evaluated different models of diversification to estimate the dynamics of lineage radiation within Calisto. By understanding the evolution of Calisto butterflies, we attempt to identify the main processes acting on insular insect diversity, the causes of its origin and maintenance. Results The crown age of the genus was estimated to the early Oligocene (31 ? 5 Ma), and one shift in diversification rate following a diversity-dependent process was the best explanation for its extant diversity assemblage. A major increase in diversification rate was recovered at 14 Ma, right after the geological arrangements that favoured the availability of empty niches. Inferred ancestral distributional ranges suggested that the origin of extant Calisto is in agreement with a vicariant model and the origin of the Cuban lineage was likely the result of the Cuba-Hispaniola split vicariance. Long-distance dispersal is supported for the colonization of Jamaica and the Bahamas. Conclusions The ancestral geographical distribution of Calisto is in line with the paleogeographical model of Caribbean colonization which favours island-island vicariance. Because the sister lineage of Calisto remains ambiguous, its arrival to the West Indies remains to be elucidated, although, given its age and historical biogeography, the hypothesized land bridge GAARlandia might have been a plausible introduction route from continental America. Intra-island radiation caused by ecological innovation and abiotic creation of niche spaces was found to be the main force shaping Calisto diversity and island endemism in Hispaniola and Cuba. } }
