We sequenced mitochondrial ۱۶S rRNA gene fragments of ۸۴ samples of Odorrana graminea (Boulenger, ۱۹۰۰) sensu lato from ۳۳ sites in southern China. Combining the newly generated sequences and congeneric sequences obtained from GenBank, we reconstructed a molecular phylogeny for the genus Odorrana Fei, Ye and Huang, ۱۹۹۰. Phylogenetic analysis revealed five highly divergent lineages which were paraphyletic within O. graminea sensu lato in southern China. The lineage from Medog and western Yunnan is assigned to O. chloronota (Günther, ۱۸۷۶). The lineage from Hainan, southeastern Guangxi, and southwestern Guangdong corresponds to O. graminea sensu stricto; the lineage from Fujian, Jiangxi, easternmost Guangxi, and northern, central, and eastern Guangdong corresponds to O. leporipes (Werner, ۱۹۳۰); and the remaining two lineages from southern Yunnan represent two cryptic new species. In addition, by checking the type specimens of O. rotodora (Yang and Rao, ۲۰۰۸) we confirmed that O. rotodora is the synonym of O. chloronota.
