Abstract

The known European record of the Gondwanan group Podocnemididae begins in the Early Eocene. Neochelys underwent a rapid diversification and was an abundant and diverse representative of this group during the Eocene of Europe from the Early Ypresian to at least the Bartonian. However, several of its species are poorly known, and the phylogenetic relationships among them are poorly understood. A complete shell from the Ypresian of Hérault (southern France) is described here. It is assigned to a new species, Neochelys liriae. The availability of characters of N. liriae is tested by comparison with the other European species, which appear to be well differentiated, and particularly with the neighbouring French taxa N. eocaenica and N. laurenti, of which the latter has been little known to this point.
