We describe a new species of the gekkonid genus Cnemaspis from Erawan National Park in Kanchanaburi Province of western Thailand. Molecular phylogenetic analyses, based on the mitochondrial NADH dehydrogenase subunit 2 gene and flanking tRNAs, revealed that Cnemaspis auriventralissp. nov. is nested within the C. siamensis group and is closely related to C. huaseesom, but has uncorrected pairwise genetic divergences of 12.12–27.92% from all other species in the C. siamensis group. The new species is also distinguished from other species in the C. siamensis group by having the combination of snout-vent length 36.7–38.6 mm in males (N = 3), 32.9–36.9 mm in females (N = 2); eight to ten supralabials; seven to nine infralabials; ventral scales smooth; six or seven precloacal pores in males; 16–17 paravertebral tubercles linearly arranged; tubercles on the lower flanks present; lateral caudal furrows present; no caudal tubercles in the lateral furrows; ventrolateral caudal tubercles present anteriorly; caudal tubercles not encircling tail; subcaudals smooth bearing a single median row of enlarged smooth scales; two postcloacal tubercles on each side; no shield-like subtibial scales; subtibial scales smooth; no enlarged submetatarsal scales; 23–27 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 of all ventral surfaces of head, body and tail in adult males. The new species is currently known only from upland karst habitat at its type locality.

泰国西部北碧府的 Cnemaspis siamensis 群(爬行动物,壁虎科)中的一种新岩壁虎

我们描述了来自泰国西部北碧府四面佛国家公园的壁虎属 Cnemaspis 的一个新物种。基于线粒体 NADH 脱氢酶亚基 2 基因和侧翼 tRNA 的分子系统发育分析揭示了 Cnemaspis auriventralissp。十一月 嵌套在 C. siamensis 组内,与 C. huaseesom 密切相关,但与 C. siamensis 组中的所有其他物种的未校正成对遗传差异为 12.12-27.92%。该新物种还与 C. siamensis 组中的其他物种区分开来,雄性的鼻子-通风口长度为 36.7-38.6 毫米(N = 3),雌性为 32.9-36.9 毫米(N = 2);八到十个上唇;七到九个下唇;腹面鳞片光滑;雄性有六个或七个前泄殖腔孔;16-17个椎旁结节线形排列;下侧有结节;侧尾沟存在;侧沟无尾结节;腹外侧尾结节在前面存在;尾结节不环绕尾巴;尾下光滑,带有一排扩大的光滑鳞片;每侧有两个后泄殖腔结节;无盾状胫下鳞片;胫下鳞片光滑;没有扩大的跖骨下鳞片;第四趾上有 23-27 个亚趾片;背侧和腹侧颜色图案的性二态;肩胛前标记缺失;无规则标记;成年雄性头部、身体和尾部的所有腹面均呈黄色。该新物种目前仅在其典型产地的高地喀斯特栖息地中为人所知。腹外侧尾结节在前面存在;尾结节不环绕尾巴;尾下光滑,带有一排扩大的光滑鳞片;每侧有两个后泄殖腔结节;无盾状胫下鳞片;胫下鳞片光滑;没有扩大的跖骨下鳞片;第四趾上有 23-27 个亚趾片;背侧和腹侧颜色图案的性二态;肩胛前标记缺失;无规则标记;成年雄性头部、身体和尾部的所有腹面均呈黄色。该新物种目前仅在其典型产地的高地喀斯特栖息地中为人所知。腹外侧尾结节在前面存在;尾结节不环绕尾巴;尾下光滑,带有一排扩大的光滑鳞片;每侧有两个后泄殖腔结节;无盾状胫下鳞片;胫下鳞片光滑;没有扩大的跖骨下鳞片;第四趾上有 23-27 个亚趾片;背侧和腹侧颜色图案的性二态;肩胛前标记缺失;无规则标记;成年雄性头部、身体和尾部的所有腹面均呈黄色。该新物种目前仅在其典型产地的高地喀斯特栖息地中为人所知。胫下鳞片光滑;没有扩大的跖骨下鳞片;第四趾上有 23-27 个亚趾片;背侧和腹侧颜色图案的性二态;肩胛前标记缺失;无规则标记;成年雄性头部、身体和尾部的所有腹面均呈黄色。该新物种目前仅在其典型产地的高地喀斯特栖息地中为人所知。胫下鳞片光滑;没有扩大的跖骨下鳞片;第四趾上有 23-27 个亚趾片;背侧和腹侧颜色图案的性二态;肩胛前标记缺失;无规则标记;成年雄性头部、身体和尾部的所有腹面均呈黄色。该新物种目前仅在其典型产地的高地喀斯特栖息地中为人所知。
