Rarely observed in the wild, the existence of the Andean mountain cat (Oreailurus jacobita) has been established based on only 3 skulls and 14 museum skins. The Andean mountain cat's evolutionary relationship to other felids based on morphological characters is largely contradictory, with evidence aligning it with South American small spotted cats (ocelot lineage) or alternatively with pantherine lineage felids. Here we describe the phylogenetic distinctiveness and placement of the Andean mountain cat using DNA extracted from pieces of nine independent pelt specimens, including one confiscated from a trapper in 1995. A phylogenetic analysis of DNA sequences from three rapidly evolving mitochondrial genes (16S rRNA, NADH-5, and ATP-8) indicate that the Andean mountain cat is a distinct species belonging to the ocelot lineage. Our findings suggest that the Andean mountain cat diverged from a common ancestor with the ocelot (Leopardus paradalis) and margay (L. wiedii) and exhibits moderate levels of genetic variation.
安第斯山猫（Oreailurus jacobita）在野外极为罕见，其存在仅基于3个头骨和14张博物馆皮毛标本得以确认。基于形态特征，安第斯山猫与其他猫科动物的进化关系在很大程度上相互矛盾，有证据表明它与南美小斑猫（豹猫谱系）相关，或者与豹亚科谱系的猫科动物相关。在此，我们使用从9个独立毛皮标本碎片中提取的DNA来描述安第斯山猫的系统发育独特性和分类位置，其中包括1995年从一名捕猎者手中没收的一个标本。对来自三个快速进化的线粒体基因（16S rRNA、NADH - 5和ATP - 8）的DNA序列进行系统发育分析表明，安第斯山猫是属于豹猫谱系的一个独特物种。我们的研究结果表明，安第斯山猫与豹猫（Leopardus paradalis）和虎猫（L. wiedii）有着共同的祖先，并表现出中等程度的遗传变异。
