A new species of the genus Odorrana (Amphibia, Anura, Ranidae) from Guizhou Province, China

Based on morphological comparisons and molecular phylogenetics, a new species of the genus Odorrana from Xiuwen and Jinsha counties, Guizhou Province, China, is described. Phylogenetic analyses of mitochondrial 16S rRNA and COI gene sequences supported the new species as a sister species to O. lipuensis . The uncorrected p-distances of 16S rRNA and COI genes between the new species and its closest congeners were 2.6% and 4.4%, respectively. The new species is distinguished from its congeners by a combination of the following characters: (1) medium body size (SVL 37.0–39.0 mm in males and 49.4–52.2 mm in females); (2) tympanum distinctly visible, greater than one-half the diameter of the eye; (3) dorsolateral folds absent in males; (4) relative finger lengths: I < II < IV < III; (5) tibiotarsal articulation reaching the nostril when the leg is stretched forward; (6) bands on the dorsal surface of the hindlimb clear; and (7) vocal sacs absent in males.
