It was supposed that the current records of might be a species complex composed of multiple species. In this study, on the basis of wide sampling, we found that the records of from Yunnan, China, and northern Vietnam actually represent a cryptic species based on morphological and molecular evidence. can be distinguished from other members of the species group by its moderate body size (SVL 35.5‒37.3 mm in males and 39.2‒45.7 mm in females); white spines on the temporal region, loreal region, snout, and lips in breeding males but absent in females; overlapping heels; tibiotarsal articulation reaching tip of snout; indistinct longitudinal glandular folds on the skin of the shoulders; presence of supernumerary tubercles below the base of fingers II‒IV, distinct pineal body; presence of vomerine teeth; and absence of vocal sacs. Phylogenetic analysis supports that the new species is sister to and the populations from Jingxi, Guangxi and Lào Cai, Vietnam previously reported as also belong to it. Additionally, our results indicate that more cryptic species may exist within the species group, implying that more studies are needed to achieve a complete understanding of the species diversity of this group.
据推测，目前的[物种名称]记录可能是一个由多个物种组成的复合物种。在本研究中，基于广泛采样，我们发现来自中国云南和越南北部的[物种名称]记录实际上代表了一个隐存物种，这是基于形态学和分子证据得出的结论。[物种名称]可以通过以下特征与该物种组的其他成员区分开来：体型适中（雄性体长35.5 - 37.3毫米，雌性体长39.2 - 45.7毫米）；繁殖期雄性的颞部、吻部、唇和吻侧有白色棘刺，雌性则无；足跟重叠；胫跗关节达吻端；肩部皮肤有不明显的纵向腺褶；第II - IV指基部下方有额外的瘤；松果体明显；有犁骨齿；无声囊。系统发育分析支持该新物种是[另一物种名称]的姐妹种，之前报道为[物种名称]的广西靖西和越南老街的种群也属于该新物种。此外，我们的结果表明，该物种组内可能存在更多隐存物种，这意味着需要更多研究来全面了解该组的物种多样性。
