abstract = {The Great American interchange resulted in the mixing of faunistic groups with different origins and evolutionary trajectories that underwent rapid diversification in North and South America. As a result, groups of animals of recent arrival converged into similar habits and formed ecological guilds with some of the endemics. We herein present a reconstruction of the evolutionary events in Aspidoderidae, a family of nematodes that infect mammals that are part of this interchange: dasypodids, opossums and sigmodontine, geomyid and hystricognath rodents. By treating hosts as discrete states of character and by using parsimony and Bayesian inferences to optimize these traits into the phylogeny of Aspidoderidae we reconstructed Dasypodidae (armadillos) as the synapomorphic host for the family. In addition, four events of host switching were detected. One consisted in the switch from dasypodids to hystricognath rodents, and subsequently to geomyid rodents. The remaining set of events consisted in a switch from dasypodids to didelphid marsupials and then to sigmodontine rodents. The reconstruction of ancestral distribution suggests three events of introgression into the Nearctic. Two of these invasions would suggest that two different lineages of parasites of dasypodids entered into the northern hemisphere at different times.}
