A new species of the genus is described from Guizhou Province, China. Molecular phylogenetic analyses supported the new species as an independent clade nested into the . The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 49.3-58.2 mm in males); vomerine ridges present distinctly, vomerine teeth present; tongue feebly notched behind; tympanum distinctly visible, oval; two metacarpal tubercles in hand; toes with one-third webbing and wide lateral fringes; heels overlapped when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between tympanum and eye when leg stretched forward; an internal single subgular vocal sac present in male; in breeding male, the nuptial pads with large and sparse black nuptial spines present on the dorsal bases of the first two fingers.
在中国贵州省发现了该属的一个新物种。分子系统发育分析支持该新物种为嵌套在该属中的一个独立分支。新物种可通过以下特征组合与同属其他物种区分开来：体型适中（雄性体长49.3 - 58.2毫米）；犁骨嵴明显，有犁骨齿；舌后部有微弱缺刻；鼓膜明显可见，呈椭圆形；手部有两个掌突；趾间有三分之一蹼且外侧边缘宽；当大腿与身体呈直角时，脚跟重叠；腿向前伸展时，胫跗关节达到鼓膜和眼睛之间的水平；雄性有一个内部单一的喉下声囊；在繁殖期雄性中，第一、二指基部背面有大而稀疏的黑色婚垫，婚垫上有婚刺。
