Abstract
The frog genus Odorrana is distributed across east and southeastern Asia. Based on morphological differences and molecular phylogenetics, a new species of the genus occurring from Leigong Mountain in Guizhou Province, China is described. Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA, 16S rRNA, and ND2 genes supported the new species as an independent lineage. The uncorrected genetic distances between the 12S rRNA, 16S rRNA, and ND2 genes between the new species and its closest congener were 5.0%, 4.9%, and 16.3%, respectively. The new species is distinguished from its congeners by a combination of the following characters: body size moderate (SVL 39.1–49.4 mm in males, 49.7 mm in female); head width larger than head length; tympanum distinctly visible; small rounded granules scattered all over dorsal body and limbs; dorsolateral folds absent; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between eye to nostril when leg stretched forward; vocal sacs absent in male and nuptial pads present on the base of finger I.

Odorrana leishanensis sp. nov.
Diagnosis: Odorrana leishanensis sp. nov. can be distinguished from its congeners by the following characters: (1) body size moderate (SVL♂ (n = 6) = 39.1–49.4 mm, SVL♀ (n = 1) = 49.7 mm in female); (2) head width larger than head length; (3) tympanum distinctly visible; (4) small rounded granules scattered all over dorsal body and limbs; (5) dorsolateral folds absent; (6) heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between eye to nostril when leg stretched forward; (7) vocal sacs in male absent, and nuptial pads in male present on base of finger I.
Etymology: The specific epithet leishanensis refers to the distribution of this species, Leishan County, Guizhou Province, China. We propose the common English name “Leishan Odorous Frog” and the Chinese name as “Lei Shan Chou Wa (雷山臭蛙)” for this species.
