• 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 Rhinebothri…

  Systematics of Rhinebothrium Linton, 1890 and the composition of the Rhinebothriidae Euzet, 1953 (Platyhelminthes: Cestoda): a new approach for an old problem in cestodes systematics, AP.R

• Abstract

  Molecular techniques have been useful throughout Biology and have been incorporated within many its disciplines due to their ability to compile data very fast and efficiently to be used to address relevant scientific questions. An example could be how molecular systematics have used nucleotide sequence data under the expectation that they could help to solve questions regarding species bo…

• Abstract

  The documentation of the diversity and phylogenetic studies of parasites are essential to the understanding of the global biodiversity and historical associations between the lineages involved. Despite the recent efforts to discover and describe new species of parasites worldwide, there are strong evidence that the diversity of many groups still underestimated. The genus Rhinebothrium Lin…

  Taxonomic diversity of Rhinebothrium Linton, 1890 (Cestoda: Rhinebothriidea) from Hypanus guttatus (Bloch & Schneider) in NE Brazilian coast, BP.IC

• Abstract

  Taxonomic studies of parasites are important to the knowledge of the biological diversity, mainly because many of these lineages are poorly known and parasites, in general, are often neglected as a component of the biota. This project is centered in the description of a new specie of Anthocephalum Linton, 1891 (Cestoda: Rhinebothriidea), a genus of cestodes parasites of marine batoids (i.…

• Abstract

  Throughout the last two decades, molecular data became an integral component of many disciplines in Biological Sciences. As such, Systematics experienced a considerable change as a result of the development of new techniques for compiling massive amounts of genomic data and new analytical tools that enable researches to answer questions not permitted before. To date, high throughput seque…

• Abstract

  In recent years, the class Cestoda has undergone considerable taxonomic 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 instance: the family Rhinebothriidae Euzet, 1953. This family includes 71 spec…
