Abstract
Based on morphological and genetic data, we describe a new species of Tropidophorus from the tropical karst landscape in southeastern Yunnan Province, China, close to the Vietnam border. Phylogenetically, the new species forms a clade with T. baviensis, T. murphyi, and T. hainanus, with p-distances ranging from 4.7–5.1% for the 16S gene and 3.9–6.8% for 12S gene. Morphologically, the new species shares the karst morphotype of Tropidophorus, particularly similar as T. murphyi and T. baviensis, in which all having a dorsally compressed head and body, smooth dorsal head scales, and distinctively keeled body scales. However, the new species can be distinguished from these similar species by numbers of supralabial scales, ventral scales, scales around the tail at the10th subcaudal, and a larger body size. We emphasize the urgency of conservation for the tropical karst landscape in northern Indochina.
基于形态学和遗传学数据，我们描述了产自中国云南省东南部靠近越南边境的热带喀斯特地貌中的一个新的Tropidophorus物种。在系统发育上，该新种与 T. baviensis、T. murphyi 和 T. hainanus 组成一个支系，16S 基因的 p 值差异为 4.7-5.1%，12S 基因的 p 值差异为 3.9-6.8%。从形态上看，新种与 Tropidophorus 具有相同的喀斯特形态，尤其与 T. murphyi 和 T. baviensis 相似，都是头和体背压扁，头背鳞片光滑，体鳞呈明显的龙骨状。然而，新种可以通过上唇鳞片、腹鳞片、尾下第 10 节周围鳞片的数量以及较大的体型与这些相似物种区分开来。我们强调保护印度支那北部热带喀斯特地貌的紧迫性。
