The bent-toed geckos of the group are widely distributed along the Thai-Malay Peninsula. Although taxonomic and phylogenetic studies of this species group have been continuously conducted, only some populations from Thailand have been included, resulting in hidden diversity within this group. In this study, we used morphological and molecular data to clarify the taxonomic status and describe a new population from Tarutao Island, Satun Province, southern Thailand. can be distinguished from its congeners by the combination of the following morphological characters: body size; tuberculation; number of dark body bands, ventral scales, and femoroprecloacal pores in males; presence of precloacal pores in females; and scattered pattern on dorsum. Phylogenetic analyses of the mitochondrial ND2 gene recovered the new species as the sister species to , with an uncorrected pairwise divergence of 9.78-12.37%. is currently only known from Tarutao Island, Thailand. The discovery of this species suggests that the diversity within the group remains underestimated and future exploration of unsurveyed areas are needed to further the understanding of this group and its geographic range.
该类群的弯趾壁虎广泛分布于泰国-马来西亚半岛。尽管对该物种群的分类学和系统发育研究一直在持续进行，但仅纳入了泰国的一些种群，导致该类群内部存在隐藏的多样性。在本研究中，我们使用形态学和分子数据来阐明分类地位，并描述了来自泰国南部沙敦府达鲁他岛的一个新种群。它可以通过以下形态特征的组合与同属其他物种区分开来：体型；瘤状突起；雄性的深色体带数量、腹侧鳞片数量以及股前泄殖腔孔数量；雌性泄殖腔前孔的存在情况；以及背部的散布图案。线粒体ND2基因的系统发育分析将新物种鉴定为[某物种]的姐妹物种，未校正的成对差异为9.78 - 12.37%。该物种目前仅在泰国的达鲁他岛被发现。这一物种的发现表明，该类群内部的多样性仍被低估，需要对未调查地区进行进一步探索，以加深对该类群及其地理范围的了解。
