岩蜥三新种线纹蜥（Cnemaspis lineogularis sp. nov.），C. phangngaensis sp. nov.，和C.在泰国-马来半岛的泰国部分描述了Chanthaburiensis和Siamensis类群的thachanaensis sp. nov.。这些新的物种区别于所有其他物种在其各自的两个组的基础上，一个独特的组合的形态特征，这是进一步支持线粒体DNA（mtDNA）的NADH脱氢酶亚基2基因（ND 2）。与Chanthaburiensis组中的所有其他物种相区别的是，Cnemaspis lineogularis sp. nov.具有较小的最大SVL 38 mm，13个椎旁结节，股骨鳞片增大，没有尾带，以及19.5-23.0%的成对序列分歧（ND 2）。蓬加象甲（Cnemaspis phangngaensis sp. nov.）与暹罗象甲群中所有其他物种的区别在于，具有10个唇下鳞片、四个连续的带孔前鳞片、线性排列的椎旁结节的独特组合，下侧翼缺乏结节，腹外侧尾部结节在前方存在，尾部结节仅限于每侧一个椎旁骨排，一个中间排的龙骨状尾下骨，和8.8-25.2%的成对序列差异（ND 2）。Thachanaensissp. nov.与暹罗组所有其他种的区别在于有10或11个唇上鳞片9-11个唇下鳞片，椎旁结节线性排列，腹外侧尾结节在前，尾结节局限于每侧的单个椎旁排，单个中间排的龙骨状尾下鳞片，缺乏单个扩大的尾下鳞片排，雄性缺乏泄殖腔后结节，第一趾基部存在扩大的跖骨下鳞片，以及13.4-28.8%的成对序列差异（ND 2）。新的系统发育分析将C. punctatonuchalis和C. vandeventeri与C. punctatonuchalis为C. huaseesom和C. vandeventeri是C. siamensis，证实了以前的假设的基础上形态。三个新的喀斯特居住的地方病的发现带来的名义泰国Cnemaspis物种的总数为15，并强调需要继续在泰国-马来半岛鲜为人知的地区，特别是那些受到威胁，往往被忽视的生物多样性热点领域的实地研究。
Three new species of Rock Geckos Cnemaspis lineogularis sp. nov., C. phangngaensis sp. nov., and C. thachanaensis sp. nov. of the chanthaburiensis and siamensis groups are described from the Thai portion of the Thai-Malay Peninsula. These new species are distinguished from all other species in their two respective groups based on a unique combination of morphological characteristics, which is further supported by mitochondrial DNA (mtDNA) from the NADH dehydrogenase subunit 2 gene (ND2). Cnemaspis lineogularis sp. nov. is differentiated from all other species in the chanthaburiensis group by having a smaller maximum SVL 38 mm, 13 paravertebral tubercles, enlarged femoral scales, no caudal bands, and a 19.5–23.0% pairwise sequence divergence (ND2). Cnemaspis phangngaensis sp. nov. is differentiated from all other species in the siamensis group by having the unique combination of 10 infralabial scales, four continuous pore-bearing precloacal scales, paravertebral tubercles linearly arranged, lacking tubercles on the lower flanks, having ventrolateral caudal tubercles anteriorly present, caudal tubercles restricted to a single paraveterbral row on each side, a single median row of keeled subcaudals, and a 8.8–25.2% pairwise sequence divergence (ND2). Cnemaspis thachanaensis sp. nov. is distinguished from all other species in the siamensis group by having 10 or 11 supralabial scales 9–11 infralabial scales, paravertebral tubercles linearly arranged, ventrolateral caudal tubercles anteriorly, caudal tubercles restricted to a single paravertebral row on each side, a single median row of keeled subcaudal scales, lacking a single enlarged subcaudal scale row, lacking postcloaclal tubercles in males, the presence of an enlarged submetatarsal scale at the base if the 1st toe, and a 13.4–28.8% pairwise sequence divergence (ND2). The new phylogenetic analyses place C. punctatonuchalis and C. vandeventeri in the siamensis group with C. punctatonuchalis as the sister species to C. huaseesom and C. vandeventeri as the sister species to C. siamensis, corroborating previous hypotheses based on morphology. The discovery of three new karst-dwelling endemics brings the total number of nominal Thai Cnemaspis species to 15 and underscores the need for continued field research in poorly known areas of the Thai-Malay Peninsula, especially those that are threatened and often overlooked as biodiversity hot spots.
