摘要：报道了发现于云南昭通水塘坝的晚中新世兔类，它与时代较早的云南禄丰地点的长褶“翼兔”(“Alilepus” longisinuosus)属于同一个种，两者栖息的环境均为潮湿的沼泽地区。前臼齿的形态表明该种是现今生活在湿润地区条纹兔(即苏门答腊兔Nesolagus)的早期代表，因此将该种更名为长褶苏门答腊兔Nesolagus longisinuosus (Qiu & Han, 1986)。Nesolagus化石记录在大约7 Ma的华南地区的证据与线粒体学研究推测Nesolagus的现生种类在晚中新世从兔科演化主线上分出来的结论一致。重建了苏门答腊兔演化历史的大致一幕，即其在8 Ma后出现，随即迅速地扩散到整个东南亚并最终到达现今的苏门答腊地区。

Abstract  The rabbit from the Late Miocene Shuitangba site in Yunnan Province represents the same species as that from the older site of Lufeng, Yunnan. Both settings record a wet, swampy habitat. Premolar morphology shows that the species is an early representative of the extant striped rabbit genus, which today lives in moist habitat, and should be designated Nesolagus longisinuosus (Qiu & Han, 1986). Fossil evidence for Nesolagus by about 7 Ma in the fossil record of South China is consistent with mitochondrial evidence for the Late Miocene split of the extant species of Nesolagus. We reconstruct a scenario for the origin of Nesolagus after 8 Ma, followed by rapid spread through Southeast Asia into present-day Sumatra.
