摘　　要：A new species of the genus Liurana is described from Medog,Xizang,China,based on morphological and molecular data.Molecular phylogenetic analysis based on the mitochondrial gene COI indicated that this new species represented an independent evolutionary lineage.In addition,the uncorrected genetic distance between the new species and its closest congener species,L.alpina,was 9.6%-9.8%for COI.The new species,Liurana namchabarwa sp.nov.Yu,Lin,Wang,Jiang and Xie,could be distinguished from its congeners by following characters:(1)relatively large body size in this genus,SVL=21.2-23.1 mm in adult males(n=3);(2)relatively narrow head(HL/HW=100.5%-104.8%(n=3));(3)digital disc not expanded;(4)relatively long hindlimbs,with tibiotarsal articulation reaching tip of snout when adpressed.
