Abstract
A new species of odorous frog, Odorrana damingshanensis sp. nov., was found at the Damingshan National Nature Reserve in Guangxi, China. This species can be distinguished from its congeners by a combination of the following characters: medium body size (SVL 52.3–54.8 mm in males and 74.8–81.2 mm in females), sawtooth spinules on the upper lip, obtusely rounded snout that extends beyond the lower margin, distinct dorsolateral folds, horny tubercles on the rear of the back, presence of outer metatarsal tubercles, dilated nuptial pad with velvety spinules, distinct maxillary gland with tiny spines, and external lateral vocal sac. Through analysis of the 16S mitochondria gene, the new species is closely related to O. nasica and O. yentuensis, but the genetic divergence between the new species and the latter exceeds 7% (uncorrected p-distance). Currently, the new species is only known from its original discovery site. Furthermore, a discussion on the taxonomy of Odorrana (Bamburana) was conducted, identifying seven species within the subgenus Odorrana (Bamburana).

Odorrana damingshanensis sp. nov.
Diagnosis: Based on both molecular analyses and specific morphological traits, these specimens were assigned to the genus Odorrana. The distinguishing morphological characteristics of these species include dilated and tapering tips of the digits, disks with circummarginal grooves and a longer vertical diameter than horizontal diameter, fully webbed toes, the absence of a tarsal fold, a thick first finger with a distinct nuptial pad, sawtooth spinules on the upper lip, and well-defined dorsolateral folds (Fei et al. 2001, 2005).

Etymology: The specific name of this species, damingshanensis, is derived from its discovery locality, Damingshan National Nature Reserve. In English, it is suggested to be called the Damingshan Bamboo-leaf Frog. In Chinese, it is known as大明山竹叶蛙(Dà Míng Shān Zhú Yè Wā).
