Abstract
A new species of the genus Odorrana is described based on specimens collected from Wenshan Prefecture, Yunnan Province, China. The new species can be distinguished from other species of the genus by a combination of the following characteristics: snout–vent length 43.5–46.9 mm in males, females approximately two times size of males, head length greater than head width, nostril closer to tip of snout than to eye, tibiotarsal articulation reaching tip of snout when hindlimb stretched forward, relative lengths of fingers III > IV > I > II, dorsolateral fold absent, anterior dorsum green with evenly distributed small irregular shaped black blotches and posterior dorsum greyish brown with evenly distributed, large, irregular-shaped, black blotches, external vocal sacs present in adult males. In addition, the new species differs from its congeners by a genetic distance of 3.6%–14.2% in the mitochondrial 16S rRNA gene.

Odorrana yangi sp. nov.
Diagnosis. Body size small in males (SVL 43.5–46.9 mm), females approximately two times size of males; head length greater than head width; nostril closer to tip of snout than to eye; tympanum relatively large in males (TD/ED 0.53–0.63); heels overlap when hindlimbs flexed at right angles to axis of body, tibiotarsal articulation reaching tip of snout when hindlimb stretched forward; relative lengths of fingers III > IV > I > II; dorsal surface relatively smooth, skin on dorsum shagreened, with some indistinct flat tubercles; dorsolateral fold absent; anterior dorsum green with evenly distributed, small, irregular-shaped, black blotches, posterior dorsum greyish brown with evenly distributed, large, irregular-shaped, black blotches; ventral surface white without distinct spots or patches; external vocal sacs and nuptial pads present in adult males.
