最近的形态和分子研究导致识别出两种现存的云豹:来自东南亚大陆的Neofelis nebulosa和来自婆罗洲和苏门答腊岛(包括巴图群岛)的Neofelis diardi。除了这些新的物种水平的区别外,初步的分子数据表明,婆罗洲云豹和苏门答腊云豹之间存在遗传亚结构,这表明可能存在两个亚种。这一建议是基于对三名苏门答腊人和七名婆罗洲人的分析。因此,在这项研究中,我们使用了额外的分子(主要是历史上的)8只婆罗洲云豹和13只苏门答腊云豹的样本,对28个标本进行了颅骨测量分析,并检查了20个博物馆标本的毛皮形态和12个野生动物的照片,从而重新评估了这种亚种分化。分子(mtDNA和微卫星座位)、颅颌和牙齿分析有力地支持婆罗洲云豹和苏门答腊云豹的分化,但皮毛特征未能完全区分它们,很可能是由于样本量小,但也可能反映出两个岛屿之间的栖息地相似和最近的分歧。然而,提出了一些临时性的鉴别毛皮特征,需要进一步的检验。根据我们的估计,这两个种群在中更新世至晚更新世(400至120 kyr之间)彼此分化。我们对Neofelis diardi SSPP的进化史进行了讨论。在Sunda陆架上,修订了Sunda云豹N.diardi的分类,并正式描述了婆罗洲的亚种Neofelis diardi Borneensis,包括根据国际动物命名法的规则指定一个正模式(BM.3.4.9.2,来自沙捞越的巴拉姆)。
Recent morphological and molecular studies led to the recognition of two extant species of clouded leopards; Neofelis nebulosa from mainland southeast Asia and Neofelis diardi from the Sunda Islands of Borneo and Sumatra, including the Batu Islands. In addition to these new species-level distinctions, preliminary molecular data suggested a genetic substructure that separates Bornean and Sumatran clouded leopards, indicating the possibility of two subspecies of N. diardi. This suggestion was based on an analysis of only three Sumatran and seven Bornean individuals. Accordingly, in this study we re-evaluated this proposed subspecies differentiation using additional molecular (mainly historical) samples of eight Bornean and 13 Sumatran clouded leopards; a craniometric analysis of 28 specimens; and examination of pelage morphology of 20 museum specimens and of photographs of 12 wild camera-trapped animals. Molecular (mtDNA and microsatellite loci), craniomandibular and dental analyses strongly support the differentiation of Bornean and Sumatran clouded leopards, but pelage characteristics fail to separate them completely, most probably owing to small sample sizes, but it may also reflect habitat similarities between the two islands and their recent divergence. However, some provisional discriminating pelage characters are presented that need further testing. According to our estimates both populations diverged from each other during the Middle to Late Pleistocene (between 400 and 120kyr). We present a discussion on the evolutionary history of Neofelis diardi sspp. on the Sunda Shelf, a revised taxonomy for the Sunda clouded leopard, N. diardi, and formally describe the Bornean subspecies, Neofelis diardi borneensis, including the designation of a holotype (BM.3.4.9.2 from Baram, Sarawak) in accordance with the rules of the International Code of Zoological Nomenclature.
