| Abstract |
The genus Spaniodon is decribed in detail. Contrary to previous authors, we have only recognized two species, S. elongatus and S. latus. Spaniodon shows the synapomorphies of clupeocephalans, protacanthopterygians and salmoniforms. Its relationships among salmoniforms are still undecided, although it could be closely related to the Osmeroidei. The main character that supports this grouping is the dermal part of the mesethmoid formed by the partial fusion of a pair of lateral dermethmoids, whereas the rostral is absent. These conclusions are also supported by a global phylogenetic study of the teleosts. |
