Twenty three new sequences, including 3 outgroups are added in our new dataset. The Gangesiinae and the Acanthotaeniinae appear to be the most primitive clades. They are followed by a robust clade comprising the Palaearctic Proteocephalinae from freshwater fishes. The structure of the more derived clades, comprising most Neotropical and Nearctic species, is less resolved. At the nomenclatural level, we erect a new genus, Glanitaenia n. g., and define an aggregate for the Palaearctic Proteocephalus. After re-examination of all studied taxa, we identify two types of uterine development and show the importance of this character for the systematics of the order. Our phylogeny does not support the classical view of a Neotropical origin of the Proteocephalidea but rather favours an Old World origin of the group either in saurians or Palaearctic Siluriformes.} }
