英文摘要	During a faunal survey in southern Xizang, we collected 27 specimens of voles that could not be identified as any known species in the Arvicolinae. These specimens shared the following morphological characteristics, not corresponding with any other arvicoline species: the first lower molar possessed five closed triangles, the third upper molar exhibited either four or three inner angles, and the tails of all specimens measured 30% of the body length. Their proximal baculum of the glans was very sturdy and trumpet-shaped, the distal baculum was tongue-like and sturdy, and the lateral bacula were very short. Molecular phylogenetic analyses based on nucleotide sequences of the mitochondrial cytochrome b (cyt b) gene clustered these specimens as a distinct lineage within the genus Neodon. According to the morphological and molecular data, we described them as a new species, Neodon linzhiensis. Our phylogenetic analysis strongly supported that Lasiopodomys fuscus, Phaiomys leucurus, Neodon sikimensis, N. irene and the new species formed a monophyletic group, not including N. juldaschi. We suggested that L. fuscus and P. leucurus should be transferred to Neodon and that N. juldaschi should be removed from this genus. Following our new delineation of Neodon, we proposed a redefinition of the morphological diagnostic characters of the genus.; Zoology; SCI(E); 0; ARTICLE; 3235; 1-22
