Abstract

In recent years, the class Cestoda has undergone considerable changes, mainly on the supra-generic categories. This restructuring was largely due to the contribution of new insights into the phylogenetic relationships of taxa based on molecular data. However, there are still numerous taxa that need revision, for example the family Rhinebothriidae Euzet, 1953. This family was recently attributed to the newly erected order Rhinebothriidea Healy, Caira, Jensen, Webster & Littlewood, 2009. But, the internal phylogenetic relationships of the family Rhinebothriidae are still poorly known, especially with respect to the apparent polyphyly of its type genus, Rhinebothrium Linton, 1890. The polyphyly of Rhinebothrium may be result of the low representativeness of species included in previous phylogenetic studies and/or the validity of species assigned to the genus. In addition, previous phylogenetic studies were based only on two molecular markers (18S and 28S ribosomal DNA), which limits the testing power of earlier hypotheses and species delimitations. On the other hand, recent technological advances (e.g., next generation sequencing, NGS) provide possibilities to obtain vast amounts of molecular data labor- and cost efficiently, allowing a more rigorous testing of existing and proposing of more robust hypotheses. Thus, the present proposal aims to provide a robust phylogenetic hypothesis for members of the Rhinebothriidae through an unprecedented number of samples and integrating NGS data, with a particular focus on the circumscription and diversity of Rhinebothrium.
