A new day gecko of the genus Cnemaspis Strauch, 1887 is described from the intermediate bioclimatic zone (Haputale Forest and Idalgashinna Forest in Badulla District) of Sri Lanka. The new species belongs to the Cnemaspis kandiana clade and was recorded from granite caves and abandoned buildings within forested areas. The region in which these habitats are located, receives relatively high annual rainfall (2500–3500 mm) and has fairly cool, moist and well-shaded conditions. The new species is medium in size (30.2–32.9 mm SVL) and can be differentiated from all other Sri Lankan Cnemaspis by the presence of small subcaudals, heterogenous dorsal scales, smooth pectoral and ventral scales, 7 or 8 supralabials and infralabials, 143–159 ventral scales, 15–17 belly scales, 95–103 mid-body scales, 122–132 paravertebrals, 3 pre-anal pores, 4 or 5 femoral pores and 17 or 18 lamellae on 4th toe. The species described herein is categorised as Critically Endangered (CR) under the IUCN Red List Criteria. The major threats for the new species are habitat loss due to expansion of commercial-scale agriculture and illicit forest encroachments. Therefore, we recommend relevant authorities to take immediate conservation action to ensure the protection of these forest areas in Haputale and Idalgashinna along with the buffer zone in the near future.

斯里兰卡的一种新的壁虎新种(Reptilia,Gekkonidae,Cnemaspis Strauch,1887年),斯里兰卡和印度物种的ND2基因系统更新

从斯里兰卡的中间生物气候带(巴杜拉区的Haputale森林和Idalgashinna森林)描述了1887年Cnemaspis Strauch属的新壁虎。该新物种属于Cnemaspis kandiana进化枝,记录于森林地区内的花岗岩洞穴和废弃建筑物中。这些栖息地所在的地区,年降水量相对较高(2500-3500毫米),气候凉爽,阴凉。新物种的大小中等(30.2–32.9 mm SVL),可以通过以下方式与所有其他斯里兰卡的Cnemaspis区分开:小尾鳍,异质背鳞,平滑的胸腹面,7或8个上踝和下唇,143– 159个腹秤,15-17个腹部秤,95-103个中体秤,122-132个椎旁骨,3个肛门前毛孔,第四趾有4或5个股孔和17或18个薄片。根据IUCN红色清单标准,此处描述的物种被归为极度濒危(CR)。新物种的主要威胁是由于商业规模农业的扩张和非法森林侵占而造成的栖息地丧失。因此,我们建议有关当局立即采取保护行动,以确保在不久的将来对Haputale和Idalgashinna的这些森林地区以及缓冲区进行保护。
