摘　　要：DEAR EDITOR,Currently,the genus Polypedates comprises 26 species distributed in South,Southeast,and East Asia.Because of their relatively low dispersal capability and intolerance to seawater,this genus is ideal for the study of terrestrial range evolution that extends into the island archipelagos of southeastern Asia.In this study,based on data compiled for Polypedates from previous studies and partial mitochondrial and nuclear genes collected in this study,we performed systematic biogeographical analysis.We confirmed a Sundaland origin for the extant genus and showed northward dispersal into mainland Southeast Asia and Asia,which coincided with the timing of paleoclimatic change from the Oligocene to Middle Miocene.Climate fluctuations had a profound impact on species diversification within the genus Polypedates.Furthermore,the Red River did not mediate species exchange between Southeast Asia and mainland Asia until the end of the Miocene,with the sudden onset of northward dispersal in several clades independently at that time.Alternatively,the lineage of widespread insular P.leucomystax strongly supports the hypothesis of terrestrial connection between island archipelagos of Southeast Asia during the Mid-Pleistocene paleoclimate fluctuations.Our biogeographical analysis also supports the recent introduction of P.leucomystax to the Philippines and Ryukyus,as previously suggested.
