The genus Capricornis Ogilby, 1837, is divided into three species and widely distributed in sourthern China, Tibet, Myanmar, IndoChinese peninsula, Malaysia peninsula, Sumatra, Japanese archipelagos and Taiwan. Using complete cytochrome b sequences (1140 bp) analyzes the genetic variation and phylogeny of genus Capricornis from Taiwan, Japan and Mainland China. Constructed by both distance and maximum parsimony methods, the phyloenetic tree distinguish the Capricornis to three clades: Formosan serow, Japanese serow, and Sumatran serow from mainland China. Formosan serow is more familiar with Sumatran serow than Japanese serow. Local populations of Formosan serow of Taiwan island and Japanese serow of the Japanese archipelagos are already differentiated. Serow and goral are apparently distinguishable. The results of Principal Component Analysis and Discriminant Analysis show that serows from Taiwan, Japan and mainland China and goral are apparently distinguishable at morphological characters. The variation of morphological analysis may be a good tool to identify serow and goral. From the paleogeology and fossil records of serow of Quaternary, we could infer that ancestors of serow from southwestern mountain of mainland China migrated to Taiwan island and Japanese archipelagos through the land bridge of east Asian islands to mainland China in the early Pleistocene caused by the glaciation of Quaternary, then separated from mainland of east Asia and speciation of serow occured in Taiwan island and Japanese archipelagos after the end of the glaciation of Quaternary.
