Une espéce nouvelle ?ophisaurus (lacertilia,anguidae) de ?oligocène des phosphorites du quercy. révision de la sous-famille des anguinae

Ophisaurus roqueprunensis is a new anguine species (Lacertilia, Anguidae) from the Oligocene of the Phosphorites du Quercy (France). Blade-like teeth are the main feature of the new taxon. Several characters demonstrate the monophyletic nature of the Anguinae subfamily. The Anguinae subfamily is now subdivided into three groups: the genusPseudopus, with enlarged (molariform) teeth at the rear of the dental row; the anguine lizards with blade-like teeth (caniniform) or theAnguis —Ophisaurus harti lineage and the AmericanOphisaurus lizards, a group that shares no derived character and, thus, is a metataxon.Ophisaurus roqueprunensis is placed within theAnguis- Ophisaurus harti lineage. Phyletic relationships within those three taxons are envisaged.
