Abstract | The osteology of the fossil priacanthid Pristigenys rutoti (= P. caduca) (Teleostei, Percoidei) from the Sands of Lede (marine Middle Eocene, Belgium) is described in details thanks to a nearly complete specimen with a skull preserved in volume and to other samples with isolated bones. A new species, Pristigenys hermani, also from the Sands of Lede, is erected on the basis of isolated bones and otoliths. The two species are compared together. It is shown that the skeletal elements and the otoliths of Pristigenys dentifer from the Eocene of England are identical to the homologous pieces of P. rutoti. The English species is put into synonymy of the Belgian species which has the priority. The evolution of the sagitta within Priacanthidae is discussed. |
