The distribution of aquatic insects has been poorly explored in quantitative analyses aiming atthe 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 knowledgeof the group has enormously increased in the last decades, achieving a sufficient background to explorebiogeographical historical patterns. Our aim is to reconstruct area history in the Neotropics using the rationaleof Barrier biogeography (Hovenkamp protocol). We present eleven mayfly phylogenies, representinggroups that evolved independently at least from the Jurassic (i.e., not a one-taxon history). With thesegroups, we conducted independent biogeographical analyses (using Vicariance Inference Program), andextracted the events that repeated in two or more clades. We found fifty-eight TVEs (Traceable VicariantEvents), from which four were found at least twice, thus constituting SVEs (Supported Vicariant Events).
