A new species of the group is described from Wang Khrachae District, Kanchanaburi Province, western Thailand based on morphological and molecular data. The new species, Rujirawan, Aksornneam & Aowphol, , is distinguished from other species in the group by having the combination of SVL 42.2 mm in adult male ( = 1), 43.7 mm in adult female ( = 1); eight supralabials; seven or eight infralabials; ventral scales smooth; nine continuous precloacal pores in male; 17 or 18 paravertebral tubercles linearly arranged; tubercles on lower flanks present; lateral caudal furrows present; no caudal tubercles in the lateral furrows; ventrolateral caudal tubercles present on original portion of tail; caudal tubercles not encircling tail; subcaudals smooth; no enlarged median subcaudal row; two postcloacal tubercles on each side of tail; no shield-like subtibial scales; subtibial scales smooth; no enlarged submetatarsal scales; 26-28 subdigital lamellae on the fourth toe; sexually dimorphic for dorsal and ventral colour pattern; prescapular marking absent; gular marking absent; and yellow colouration in life on all ventral surfaces of head, body and tail in adult male. Phylogenetically, the new species is recovered as the sister taxon to , but the two species are separated by 8.3-9.4% uncorrected pairwise genetic divergences in the mitochondrial NADH dehydrogenase subunit 2 gene and flanking tRNAs.
基于形态学和分子数据，在泰国西部北碧府王克拉猜区描述了该类群的一个新物种。新物种Rujirawan、Aksornneam和Aowphol，与该类群中的其他物种的区别在于，成年雄性（n = 1）的体长为42.2毫米，成年雌性（n = 1）的体长为43.7毫米；有8枚上唇鳞；7或8枚下唇鳞；腹鳞光滑；雄性有9个连续的泄殖腔前孔；17或18个椎旁瘤呈线性排列；下侧腹有瘤；有尾侧沟；尾侧沟内无尾瘤；尾基部有腹侧尾瘤；尾瘤不环绕尾部；尾下鳞光滑；无扩大的中间尾下鳞行；尾两侧各有2个泄殖腔后瘤；无盾状胫下鳞；胫下鳞光滑；无扩大的跖下鳞；第四趾有26 - 28枚趾下瓣；背腹颜色模式存在两性异形；无肩前斑；无喉斑；成年雄性头部、身体和尾部所有腹面在生活时呈黄色。在系统发育上，新物种被恢复为与[物种名称未给出]的姐妹分类单元，但这两个物种在线粒体NADH脱氢酶亚基2基因和侧翼tRNA中的未校正成对遗传差异为8.3 - 9.4%。
