The specificity is one of the main features of parasites. The founding of highly specific parasite species can offer information on their hosts. Also, the host specificity describes patterns of current association that can reflect the macroevolutive history. The host specificity of the Syphaciini (Oxyuridae) nematode parasites of American Muroidea (Rodentia) and akodontine rodents was analyzed in this study. On the other hand, with the aim of distinguishing possible evolutionary events, the taxonomic-ecological knowledge and the results of specificity of Syphaciini were integrated with the phylogeny of the Akodontini rodents. The results showed correspondence between parasite specie-genus host and explain that these parasites accompany the diversification of their hosts. As regarded, it is suggested that these nematodes would be useful as taxonomic markers of the evolutionary history of their hosts.
