Relations phylogénétiques des Gonorhynchiformes (Ostariophysi).

The relationships of the fossil and living Gonorhynchiformes are reviewed and modified. The families Judeichthidae (Upper Cretaceous), Charitosomidae (Upper Cretaceous) and Gonorhynchidae (Tertiary and Recent) belong to the suborder Gonorhynchoidei. The suborder Chanoidei is paraphyletic. The genus Chanos is considered the sister-group of Kneriidae + Phractolaemidae + Gonorhynchoidei, the last one including fossil and recent forms. The phylogenetic position of Ramallichthys is reviewed so the place of Gonorhynchiformes inside the Ostariophysi.
