摘　　要：The origin and colonization history of Kurixalus,a genus of small arboreal tree frogs breeding exclusively in shallow swamps,is under disputed.On the basis of comprehensive sampling program,the evolutionary history of Kurixalus is investigated based on 3 mitochondrial genes.Our results indicate that the genus Kurixalus originated in the Asian mainland and subsequently arrived at its current distribution in Borneo,Taiwan,Ryukyu,and Hainan islands by a series of dispersal events.Moreover,the colonization of Taiwan from mainland Asia has occurred 2 times.The initial colonization of Taiwan occurred at 3.46-8.68 Mya(95%highest posterior density),which rejects the hypothesis that Kurixalus probably originated from Taiwan during the early Oligocene and favors the model of Neogene-origin rather than the model of Quaternary-origin for Taiwan Residents Kurixalus.Kurixalus eiffingeri has dispersed from Taiwan to the Ryukyus once or 2 times pending more data.Both transoceanic dispersal and landbridge dispersal have played a role in the colonization process;the former resulted in the colonization of Taiwan and the Ryukyus and the latter led to the colonizati on of Bor neo and Hain an.
