Podogymnura, a Philippine endemic genus of gymnures ("soft-furred hedgehogs"), has been known previously only from the highlands of central Mindanao (P. truei truei and P. t. minima) and from two small islands off the northeast tip of Mindanao (P. aureospinula). Based on a combination of mitochondrial genetic and qualitative and quantitative morphological data, we recognize P. minima, formerly considered a subspecies of P. truei, as a distinct species. We also recognize specimens from two little-studied montane regions of southeastern Mindanao, Mt. Hamiguitan and Mt. Kampalili, as a distinctive new species, P. intermedia n. sp. We estimate that dispersal of a common ancestor from Borneo to Mindanao ca. 1.9 to 3.5 Ma gave rise to Podogymnura, followed by speciation within Mindanao beginning 0.53 to 0.97 Ma. These results further increase the rich diversity of mammals on Mindanao, and underscore the importance of the eastern Mindanao highlands as a likely important but little-studied center of Philippine mammalian diversity.
菲律宾特产的裸足猬属（“毛软猬”）动物，此前仅在棉兰老岛中部高地（真裸足猬指名亚种和微小裸足猬）以及棉兰老岛东北端外的两个小岛上（金色裸足猬）被发现过。基于线粒体基因以及定性和定量形态学数据的综合分析，我们将此前被视为真裸足猬一个亚种的微小裸足猬认定为一个独立物种。我们还将来自棉兰老岛东南部两个研究较少的山区——哈米吉坦山和坎帕利利山的标本认定为一个独特的新物种，即中间裸足猬新种。我们估计，约在190万至350万年前，一个共同祖先从婆罗洲扩散至棉兰老岛，从而产生了裸足猬属，随后在053万至097万年前棉兰老岛内开始出现物种形成。这些结果进一步增加了棉兰老岛哺乳动物的丰富多样性，并凸显了棉兰老岛东部高地作为菲律宾哺乳动物多样性一个可能重要但研究较少的中心的重要性。
