title: Morphological and biometric revision of the cleithra, opercular and pharyngeal bones of Iberian teleosts belonging to the genus Barbus (Pisces, Cyprinidae).
abstract: Species of the genus Barbus present in the Iberian Peninsula are an interesting study group, due to its diversity and complex taxonomic position. In this work, 299 specimens of eight species were studied. All of them are endemic to the Iberian Peninsula, except for Barbus meridionalis. Cleithra, opercular and pharyngeal bones were extracted from each specimen. These bones were morphologically compared and measured, obtaining biometric indices. From these indices, the biometric differences of each bone were analysed with a principal component analysis. Later, a principal component analysis and a discriminant analysis were performed considering the three bones together. The morphological differences and similarities are congruous with the biometric results. In addition, this osteological comparison partially agrees with the present taxonomic position of these species, being a contribution to the systematics and phylogeny of genus.
