The distribution of aquatic insects has been poorly explored in quantitative analyses aiming at the historical reconstruction of area relationships in the Neotropics. Ephemeroptera is an ancient group, characterized by its low vagility, and of high richness and endemicity in this region.Systematic knowledge of the group has enormously increased in the last decades, achieving a sufficient background to explore biogeographical historical patterns. Our aim is to reconstruct area history in the Neotropics using the rationale of Brarrier biogeography (Hovenkamp protocol). We present eleven mayfly phylogenies, representing groups that evolved independently at least fromthe Jurassic (i.e., not a one-taxon history). With these groups, we conducted independent biogeographical analyses (using Vicariance Inference Program), and extracted the events that repeated in two or more clades. We found fifty-eight TVEs (Traceable Vicariant Events), from which four were found at least twice, thus constituting SVEs (Supported Vicariant Events).
