We describe a new species of the genus based on five adult specimens from Bac Ha District, Lao Cai Province, northern Vietnam. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following morphological characteristics: medium size (SVL up to 89.5 mm); dorsal tubercles in 17-19 irregular transverse rows; ventral scales in 32-34 longitudinal rows at midbody; precloacal pores present in both sexes, 9 or 10 in males, 8 or 9 in females; 12-15 enlarged femoral scales on each thigh; femoral pores 9-12 in males, 5-10 in females; postcloacal tubercles 2-4; lamellae under toe IV 21-23; dorsal pattern consisting of 5 or 6 irregular dark bands, a thin neckband without V-shape or triangle shape in the middle, top of head with dark brown blotches; subcaudal scales transversely enlarged. Molecular phylogenetic analyses recovered the new species as the sister taxon to from Yunnan Province, China, with strong support from all analyses and the two taxa are separated by approximately 8.87-9.22% genetic divergence based on a fragment of the mitochondrial ND2 gene. This is the first representative of known from Lao Cai Province.
我们基于来自越南北部老街省巴沙县的5个成年标本描述了该属的一个新物种。该新物种与其他印度支那弯趾壁虎的区别在于以下形态特征的组合：中等体型（头体长可达89.5毫米）；背部瘤鳞有17 - 19排不规则横纹；身体中部腹侧鳞片有32 - 34排纵列；两性均有泄殖腔前孔，雄性9或10个，雌性8或9个；每条大腿有12 - 15枚扩大的股鳞；雄性股孔9 - 12个，雌性5 - 10个；泄殖腔后瘤2 - 4个；第四趾下瓣21 - 23枚；背部图案由5或6条不规则深色带组成，颈部有一条细带，中间无V形或三角形，头顶有深褐色斑点；尾下鳞片横向扩大。分子系统发育分析确定该新物种为中国云南省[物种名称未给出]的姐妹分类单元，所有分析均提供了有力支持，基于线粒体ND2基因片段，这两个分类单元的遗传分歧约为8.87 - 9.22%。这是老街省已知的该属的首个代表物种。
