A new genus of Lacertidae (Reptilia, Lacertilia) from the Miocene deposits of Anjou-Touraine (Maine-et-Loire, France).

A lacertid lizard, Pseudeumeces pouiti Augé, 1993, with posterior enlarged teeth (amblyodont teeth), was described from the middle Miocene locality of Pontbrault (France). New material (a dentary), referred to this species, differs sharply from the dentary of the type species Pseudeumeces cadurcensis (Filhol, 1877) and demonstrates that the species represents a distinct genus. Here we propose to erect a new genus, Ligerosaurus n. gen. Stratigraphic ranges and phyletic relationships of the european lacertid lizards during the Paleocene and the early Neogene are discussed.
