我们之前发现，基于线粒体DNA序列分析，西表猫与广泛分布于亚洲的豹猫Felis bengalensis非常接近[24]。在这项研究中，为了了解Tsushima猫，这是在日本的另一种野猫的系统发育地位，线粒体细胞色素B区的部分序列（402个碱基）进行了测定，并与西表猫和其他猫科动物的比较。细胞色素B序列的系统发育树表明，对岛猫和西表猫与豹猫具有相同的线粒体DNA谱系，在这两种日本野猫和豹猫之间观察到一个或两个过渡性替换。根据序列资料推测的对马岛猫和豹猫的化石年代（约10万年前）与对马岛的形成年代相一致。这些结果表明，对岛猫和西表猫在地理隔离后的遗传漂变中，部分遗传和形态特征已被固定，而这两种日本野猫在遗传上仍与大陆豹猫接近。孟加拉人。
We previously revealed, based on mitochondrial DNA sequence analysis, that the Iriomote cat is very closely related to the leopard cat Felis bengalensis, which is widespread in Asia [24]. In this study, in order to understand the phylogenetic status of the Tsushima cat which is the other wildcat in Japan, partial sequences (402 bases) of the mitochondrial cytochrome b region were determined and compared with those of the Iriomote cat and other feline species. The phylogenetic tree of the cytochrome b sequences indicated that the Tsushima cat and the Iriomote cat have the same mitochondrial DNA lineage as the leopard cat. One or two transitional substitutions were observed among the two Japanese wildcats and the leopard cat. The divergence time (approximately 100,000 years ago) of the Tsushima cat and the leopard cat, estimated by sequence data, was in concordance with the formation date of the Tsushima Island. These results suggest that genetic drift after geographic isolation has brought fixation of some genetic and morphological characters to the Tsushima cat and the Iriomote cat, while these two Japanese wildcats are still genetically close to the continental leopard cat. Considering morphological differences and molecular phylogeny, it is reasonable for the two Japanese wildcats to be classified as two subspecies of F. bengalensis.
