Abstract
- Abstract: Prolagus italicus n. sp., a new endemic Pliocene species of peninsular Italy, is described here, adding new details to the knowledge of this widespread and long-lasting ochotonid genus. Several dental morphodimensional characters suggest a close relationship between P. italicus and P. sorbinii (evaporitic and postevaporitic Messinian, central Italy). On the other hand, P. italicus shares with other Plio-Pleistocene Prolagus species of continental Europe a large size and some peculiar characters of dental occlusal surface. Actually, an evolutionary trend can be detected in Plio-Pleistocene species of the genus Prolagus. The value of P. italicus in biochronology is quite consistent, as this species seems to mark MN17 in central Italy. Moreover, some morphodimensional differences between P. italicus populations have been identified: this can help to infer relative chronological positions to the fossil sites in which P. italicus is present. Some morphological characters present in one of the two available P. italicus populations are apparently related to ecological more than to evolutionary factors: this may be a starting point for in-depth palaeoecological studies related to the genus Prolagus. The presence of P. italicus in the Italian peninsula may have prevented the entrance of other species of western European affinity. [Copyright &y& Elsevier]
