Abstract: In China the living porcupines are known to be distributed in Tibet and the area south to the Yangtze River, not beyond N 35°. The distribution of Quaternary fossil porcupines is known to be much wider than that of today, reaching Benxi in Northeastern China (north to N 41°) . However, our knowledge of the Chinese Neogene porcupines is limited to two species from south China: H. Zhengi from Pliocene of Sichuan and Guangxi, and Hystrix sp. from late Miocene of Lufeng of Yunnan. So far no fossil porcupines have ever been reported from Gansu Province. The discovery of the new porcupine from Linxia, Gansu, not only widened the distribution of the Neogene porcupines in China , but also shed new light on the evolutionary history of the fossil porcupines .

摘要： 在甘肃临夏盆地发现豪猪化石一新种，甘肃豪猪(Hystnx gansuensis):其主要特征是:个体大;鼻骨较宽大，后缘圆凸，达M3的后上方;门齿与P4间齿缺长，胯面较宽，两齿列彼此近于平行;后鼻孔前缘弧形;颊齿为中度单面高冠;P4的前边脊短，褶I向颊侧开口，具低小的前附尖;上臼齿褶I不向颊侧开口;M3较少退化。根据共生的哺乳动物群判断，其时代为晚中新世.
