Tlirolian and Ruscinian porcupines (genus<Emphasis Type="Italic">Hystrix</Emphasis>, Rodentia) from Europe,Asia and North Africa

Specimens of the larger Neogene porcupines, generally allocated toHystrix primigenia (Wagner, 1848), from 17 localities are studied, and their taxonomic status is recon-sidered. Material from one of these localities has recently been described asHystrix depereti Sen, 2001. The diagnoses of both species are revised. Tooth size and crown height are considered diagnostic characters at the species level. As a resuit, specimens from eight localities are allocated toH. primigenia, from eight other localities toH. depereti, and from one locality toHystrix sp. indet. The level of specialisation of the cranial morphology of these fossil species is compared withH. refossa Gervais, 1852 and with extant species. Diagnostic characters ofH. aryanensis SEN, 2001 and ofH. zhengi van Weers & Zhang, 1999, are discussed.
