The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polonicus. The Late Villanyian localities are well characterized with M. pliocaenicus, M. pitymyoides and M. tigliensis.The older part of the Early Biharian is documented by assemblages containing Microtus (Allophaiomys) ex gr. pliocaenicus, M. pusillus,M. cf. ostramosensis and M. tornensis, while the later part of the Early Biharian, is characterized by advanced Microtus (Allophaiomys)species occurring together with M. pusillus or M. blanci. In the Late Biharian M. savini, Microtus hintoni-gregaloides, Microtus (Iberomys)ex gr. huescarensis-brecciensis and Terricola arvalidens occur. The Early Toringian with A. mosbachensis, Allocricetus bursae, Pliomysepiscopalis and small-sized Microtus brecciensis, and the Late Toringian with A. terrestris in diversified associations are quoted. The most important faunal events are calibrated by independent chronological controls, thanks to the record of small mammals from lacustrine deposits. Several figures illustrate the most significant rodent species occurring in the succession of selected Italian localities.
