﻿AbstractIn this study, based on morphological and molecular data, a new bush frog species is described from Yunnan, China. Eleven samples ofRaorchestesmalipoensissp. nov. were collected from Malipo County, southeastern Yunnan. This species can be distinguished from other congeners by a combination of 13 morphological characters. Phylogenetic analyses based on the 16S rRNA gene indicate that these individuals form a monophyletic group, and genetic divergence between this clade and its closest relatives is higher than 3.1%, which is comparable to the divergence between recognizedRaorchestesspecies. The discovery of this new species suggests that additional extensive surveys in the southeastern Yunnan would yield more amphibian lineages yet unknown to science.
