SUMMARY:

The aim of this study is to contribute information about the helminth fauna of the rodent Delomys dorsalis, collected in the Itatiaia National Park, Rio de Janeiro. Despite the scarcity of information about the parasitic community of this small mammal, this study allowed the description of a new species of nematode and the redescription of an already known species, updating the knowledge about the helminth fauna of this host. Alippistrongylus itatiaensis was described using integrative taxonomy and characterized by being different from the other two species of the genus, through the pattern of rays present in the copulatory pouch of the male and the spherical appendage in the female. On the other hand, it was seen as necessary to contribute new and more updated taxonomic information about the nematode species Protospirura numidica, adding morphological and molecular data. Thus, the use of integrative taxomony tools such as SEM and molecular biology proved to be relevant in the descriptions and redescriptions of species, including information that could help in the identification of new species and in understanding the relationships between parasites and hosts.
