We used morphological and genetic data to assess the taxonomic status of Rana amurensis coreana and R. a. amurensis. Morphological comparisons revealed these two subspecies to be different from each other in size of body, nature of tubercles on dorsal stripe, degree of development in toe webbing, and condition of lateral spots of trunk. They were also different in sequence of mitochondrial 16S rRNA gene, with genetic distance as large as those observed among different species of brown frogs. Therefore, Korean populations previously considered a subspecies of R. amurensis should be regarded as a distinct species (=R. coreana).
我们利用形态学和遗传学数据来评估东北林蛙朝鲜亚种（Rana amurensis coreana）和东北林蛙指名亚种（R. a. amurensis）的分类地位。形态学比较显示，这两个亚种在体型、背纹上瘤的特征、趾蹼发育程度以及躯干侧斑情况等方面彼此不同。它们在线粒体16S rRNA基因序列上也存在差异，遗传距离与在不同种类的林蛙之间观察到的一样大。因此，先前被认为是东北林蛙一个亚种的朝鲜种群应被视为一个独立的物种（=R. coreana）。
