The karst landform in Yunnan Province, China, represents one of the most biodiverse regions for . Previous research has revealed that the karst forests in this province host a greater diversity of than previously acknowledged. However, substantial fundamental data essential for taxonomic and biogeographical studies are lacking. We conducted extensive surveys for in the Yunnan Province that led to the discovery of three new species from Menglian Dai, Lahu, and Wa Autonomous County and Jinghong City based on morphological and genetic data. A phylogenetic reconstruction based on the ND2 gene (1038 bp) placed the three new species into clade 3 and clade 4 of Agung et al. The uncorrected genetic pairwise distance of the Menglian specimens were greater than 5.7%, and those of the Jinghong City specimens were greater than 5.2% and 8.5%, respectively. They could be distinguished from their congeners by body size, chin scales, internasal scales, ventral scales, dorsal scales, and the total number of femoral and precloacal pores. Furthermore, we update the distributional knowledge of the known species.
中国云南省的喀斯特地貌是生物多样性最为丰富的地区之一。此前的研究表明，该省的喀斯特森林拥有比之前认知中更为丰富的[物种名称未明确]多样性。然而，分类学和生物地理学研究所需的大量基础数据仍然匮乏。我们在云南省对[物种名称未明确]进行了广泛调查，基于形态学和遗传学数据，在孟连傣族拉祜族佤族自治县和景洪市发现了三个新物种。基于ND2基因（1038碱基对）构建的系统发育树将这三个新物种归入阿贡等人研究中的分支3和分支4。孟连标本的未校正遗传成对距离大于5.7%，景洪市标本的未校正遗传成对距离分别大于5.2%和8.5%。它们可以通过体型、颏鳞、鼻间鳞、腹鳞、背鳞以及股孔和肛前孔的总数与同属其他物种区分开来。此外，我们更新了已知物种的分布信息。
