In 2012 and 2013, we collected six specimens of odorous frogs from Tianping Mountains located in Hunan Badagongshan National Nature Reserve. Results of morphological comparisons and molecular phylogenetic analyses showed that these specimens belong to the species Odorrana yizhangensis. These specimens presented almost same diagnosis of O. yizhangensis: body size smaller, Snout-vent length (SVL) of male 52.45 ± 2.54 mm (48.96﹣54.92 mm, n = 3), of female 73.11 ± 1.43 mm (71.26﹣74.74 mm, n = 3) (Table 2), which little bigger than those of types; irregular brown spots are big and crowded on dorsum of body; belly brown, with few stripes; hind side of thigh light in color with dark spots (Fig. 1a, b). Based on 16S rRNA gene data (502 bp), the phylogenetical analyses suggested that the specimens from Tianping Mountains were clustered together with other known populations into a monophyly corresponding to the species O. yizhangensis (Fig. 2a, b), the genetic distances between Mt. Tianping and other known populations of O. yizhangensis (0.002 0﹣0.008 1) were distinctly smaller than that between O. yizhangensis and O. lungshengensis (0.035 2﹣0.043 9) (Table 3); indicating that the odor frog specimens from Mt. Tianping should belong to the species O. yizhangensis. This work provided new information to the geographical distribution and systematics about the species.
