Abstract
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.

Odorrana feii sp. nov.
Diagnosis. Odorrana feii sp. nov. is assigned to the genus Odorrana based upon molecular phylogenetic analyses and the following morphological characters: (1) dorsum is mostly green; (2) tips of digits dilated, tapering, disks with circum-marginal grooves or lateroventral grooves, and vertical diameter longer than horizontal diameter in the disks; (3) supernumerary tubercle below the base of fingers III and IV; (4) feet fully webbed to disks, without tarsal fold; (5) dorsal skin smooth, dorsolateral folds absent or fine (Fei et al. 2009; Li et al. 2018).
Odorrana feii sp. nov. is distinguished from congeners by a combination of the following characters: (1) having 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 hind-limb clear; and (7) vocal sacs absent in males.
Etymology. The specific epithet ‘Feii’ is in commemoration of Fei Liang, a renowned Chinese herpetological taxonomist who made significant contributions to the study of the genus Odorrana. For the common English name “Fei’s Odorous Frog” and Chinese name “Fei Shi Chou Wa (费氏臭蛙)”.
