An integrative analysis recovered a new species of the group from a karst formation in Lung Cu Commune, Dong Van District, Ha Giang Province, northeastern Vietnam. is embedded within clade 6 of the group, bearing an uncorrected pairwise sequence divergence of 4.6-20.2% from all other species based on a 1,038 base pair segment of the mitochondrial NADH dehydrogenase subunit 2 gene (ND2). It is diagnosable from other species in clade 6 by statistically significant mean differences in normalized morphometric, meristic, and categorical characters. A multiple factor analysis using the three aforementioned character types recovered its unique, non-overlapping placement in morphospace as statistically significantly different from that of all other species in clade 6. The description of this new species contributes to a growing body of literature underscoring the high degree of herpetological diversity and endemism in karst landscapes in Vietnam as well as in the genus .
一项综合分析从越南北部东北地区河江省同文县龙贵公社的一个喀斯特地层中发现了该类群的一个新物种。该物种嵌入该类群的进化枝6中，基于线粒体烟酰胺腺嘌呤二核苷酸脱氢酶亚基2基因（ND2）的1038个碱基对片段，与所有其他物种的未校正成对序列差异为4.6%-20.2%。通过标准化形态测量、可数性状和分类性状的统计显著平均差异，可将其与进化枝6中的其他物种区分开来。使用上述三种性状类型的多因素分析发现，其在形态空间中的独特、不重叠位置与进化枝6中的所有其他物种在统计上有显著差异。这个新物种的描述为越来越多的文献做出了贡献，这些文献强调了越南喀斯特地貌以及该属中高度的爬行动物多样性和特有性。
