is described from Si Sawat District, Kanchanaburi Province, in western Thailand. The new species superficially resembles Taylor, 1962 from southern Thailand. However, differences between the new species from and other congeners were supported by an integrative taxonomic analysis of molecular and morphological data. Phylogenetic analyses based on the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene showed that the new species is a member of the group and closely related to sp. MT468911 from Thong Pha Phum National Park, Thong Pha Phum District, Kanchanaburi Province. Uncorrected pairwise genetic divergences (-distances) between the new species and its congeners, including , ranged from 7.7-17.7%. can also be distinguished from all members of the group by having a unique combination of morphological characters, including a snout to vent length of 53.7-63.3 mm in adult males and 58.6-75.8 mm in adult females; 22-34 paravertebral tubercles; 34-42 ventral scales; 30-39 enlarged contiguous femoroprecloacal scales; femoral pores and precloacal pores absent in both sexes; four or five rows of postprecloacal scales; enlarged median subcaudal scales absent; weak ventrolateral folds present; 4-7 rows of paired, paravertebral, dark-brown blotches edged in yellow or yellowish white; and two rows of small, diffuse, yellow or yellowish white spots on flanks. The new species occurs in a narrow range of forest at mid to low elevations associated with karst landscapes in the Tenasserim mountain range.
该物种发现于泰国西部北碧府的四色菊县。这个新物种表面上类似于1962年在泰国南部发现的泰勒物种。然而，通过对分子和形态数据的综合分类分析，支持了该新物种与其他同属物种之间的差异。基于线粒体NADH脱氢酶亚基2（ND2）基因的系统发育分析表明，该新物种是该种群的一员，并且与北碧府通帕蓬县通帕蓬国家公园的MT468911物种密切相关。该新物种与其同属物种（包括……）之间的未校正成对遗传差异（-距离）范围为7.7%-17.7%。该新物种还可以通过独特的形态特征组合与该种群的所有成员区分开来，包括成年雄性的吻肛长度为53.7-63.3毫米，成年雌性为58.6-75.8毫米；22-34个椎旁瘤；34-42个腹侧鳞片；30-39个连续扩大的股前泄殖腔鳞片；两性均无股孔和泄殖腔前孔；四或五排泄殖腔后鳞片；无扩大的中位尾下鳞片；有微弱的腹侧褶皱；4-7排成对的、椎旁的、边缘为黄色或黄白色的深褐色斑点；以及身体两侧有两排小的、分散的、黄色或黄白色斑点。该新物种出现在丹那沙林山脉中低海拔的与喀斯特地貌相关的狭窄森林区域内。
