描述了产自中国内蒙古晚渐新世早期的瘤齿短面猬(Exallerix pustulatus)新材料，补充和厘定了该种的下颌和下齿列特征，并与其他短面猬属种进行了初步比较。瘤齿短面猬此前仅见于蒙古湖谷地区塔钦郭勒(Taatsiin Gol)的三达河组(Hsanda Gol Formation); 苏尼特左旗的新材料代表了Exallerix在中国的首次发现。还对中国其他短面猬材料进行了讨论，结果肯定了皋兰山后短面猬(Metexallerix gaolanshanensis)的有效性，并认为其生存年代为晚渐新世晚期，约25 Ma; 内蒙古大庙16地点的短面猬材料很可能归入到准噶尔合短面猬(Synexallerix junggarensis), 而非皋兰山后短面猬。

This article describes new fossil material of Exallerix pustulatus from the early Late Oligocene of Nei Mongol, China. The specimens supplement and clarify certain mandibular and lower dental morphological features of this species, allowing for further comparisons with other short-faced hedgehogs. Previously, E. pustulatus had only been recorded from the Hsanda Gol Formation at Taatsiin Gol, in the Valley of Lakes, Mongolia. This discovery of new material from Sonid Left Banner marks the first occurrence of the genus Exallerix in China. In addition, discussions of other short-faced hedgehog fossils from Chinese localities confirm the validity of Metexallerix gaolanshanensis, which lived during the late Late Oligocene, approximately 25 Ma. Furthermore, the short-faced hedgehog specimens from locality Damiao 16 in Nei Mongol are tentatively referred to Synexallerix junggarensis, rather than M. gaolanshanensis.
