Taxonomy of subgenus Temnoclemmys Bergounioux, 1958 (Testudines: Geoemydidae: Ptychogasterinae) based on new material from the Vallès-Penedès Basin (NE Iberian Peninsula)

The taxonomy of the freshwater turtle subgenus Ptychogaster (Temnoclemmys) (Testudines,Geoemydidae, Ptychogasterinae) is revised based on new and previously-published mate-rial from the Vallès-Penedès Basin (NE Iberian Peninsula). Additional remains of subgenusPtychogaster, first reported from this basin, are also described. Although the oldest remainsof Temnoclemmys are left unassigned, most of the available remains are attributed to its typespecies, Ptychogaster (Temnoclemmys) batalleri, originally described from the Late Miocene(MN9 and MN10) of this basin. The new material expands the chronostratigraphic rangeof P. batalleri in the Vallès-Penedès Basin back to the MN7 + 8 and shows that “Testudo”celonica is its junior synonym. Emended diagnoses for Ptychogaster and Temnoclemmys arealso provided.
