Abstract

In recent years, the class Cestoda has undergone considerable changes, mainly on the supra-generic categories. This restructuring was mostly due to the contribution of new insights into the phylogenetic relationships of taxa based on molecular data. However, numerous taxa still need to be revised. For example, the family Rhinebothriidae Euzet, 1953, and notably its type-genus Rhinebothrium Linton, 1890. The family Rhinebothriidae includes 64 species which exclusively parasitize batoids worldwide (i.e., rays and skates). Despite the diversity of these hosts in Brazilian coastal waters, of which 78% of species have been reported from the state of São Paulo, records of marine rhinebothriids are entirely absent. Given the diversity of batoids present in marine environments of Brazil and the fact that they act as primary hosts for rhinebothriids, it is expected that numerous species are yet to be discovered in this biogeographic region. Within this context, our research proposal aims to advance the understanding and documentation of the biodiversity for this group of parasites targeting representatives of our biota and from other biogeographical areas. The understanding of the full spectrum of rhinebothriid diversity is crucial to elucidate the composition of the family and to circumscribe its type-genus. Thus, the present proposal will provide a robust phylogenetic hypothesis for members of the Rhinebothriidae, using genomic and morphological data, focusing on the systematic revision of Rhinebothrium by the insertion of the Brazilian parasite fauna to the phylogeny of the family.
