【摘要】A new species, Amolops mahabharatensis sp.nov., is described from Mahabharat range(middle mountain) of Nepal. The new species is a member of the A. marmoratus group and is distinguished from its congeners using morphological and molecular data.The new species is diagnosed by having numerous warts on dorsum and flanks, dorsal body greyish olivebrown/light brown, presence of vomerine teeth series,presence of a pair of subgular vocal sacs in males and tadpole with Ⅲ:5+5/1+1:Ⅱ– labial tooth row. In addition,evidenced by the phylogenetic and morphological analyses in this study, Amolops nepalicus is shown to be a valid species. A molecular phylogenetic analysis based on 16 S ribosomal gene for six members of the A. marmoratus group suggested that the new species is sister to a clade containing A. nepalicus and A. panhai.The uncorrected genetic divergences between the new species and its closest congeners A. nepalicus, A. panhai and A. marmoratus based on 16 S rRNA gene were 10.5%,11.6%, and 8.6% respectively. The new species showed wide distribution in the Mahabharat range of Nepal.
