A new species of the genus , , is described in this study based on morphological, molecular, and bioacoustic data. The species was discovered in the Shiwandashan National Nature Reserve in Shangsi County, Guangxi, China. Phylogenetically, is closely related to . However, there are distinct morphological differences between and , as well as three other sympatric species (, , and ). These differences include body size (SVL 30.5-32.5 mm in males; 38.7-41.8 mm in females in the new species vs 25.5-28.0 mm in males, 31.5-35.0 mm in females in ), the absence of brown spots on the ventral surface (vs chest and belly creamy white with many scattered brown spots in ), 1/3 toe webbing and wide toe lateral fringes (vs no toe webbing and no lateral fringes in ), and distinct dermal ridges under toes (vs absent in ). Furthermore, the dominant vocal frequencies of the new species range from 7.3 to 8.3 kHz, which is unique compared to other species and represents the highest dominant frequencies ever recorded. The Shiwandashan National Nature Reserve is now home to four known sympatric species of .
本研究基于形态学、分子学和生物声学数据描述了 属的一个新物种。该物种在中国广西上思县十万大山国家级自然保护区被发现。在系统发育上， 与 密切相关。然而， 与 以及其他三个同域分布物种（ 、 和 ）之间存在明显的形态差异。这些差异包括体型（新物种雄性的体长为30.5 - 32.5毫米；雌性为38.7 - 41.8毫米，而 在雄性中为25.5 - 28.0毫米，雌性中为31.5 - 35.0毫米）、腹面无褐色斑点（ 胸部和腹部为乳白色且有许多散在褐色斑点）、1/3的趾间有蹼且趾外侧边缘宽阔（ 在趾间无蹼且无外侧边缘）以及趾下有明显的皮嵴（ 在趾下没有）。此外，新物种的主导发声频率范围为7.3至8.3千赫兹，这与其他 物种相比是独特的，并且代表了有记录以来的最高主导频率。十万大山国家级自然保护区现在是已知的四种同域分布的 的栖息地。
