A new species of forest dwelling Rock Gecko, Cnemaspis roticanai sp. nov., is described from the upper elevations of Gunung Raya, Pulau Langkawi, Kedah, Peninsular Malaysia. Cnemaspis roticanai is the second species of Cnemaspis described from Pulau Langkawi and is differentiated from all other Southeast Asian Cnemaspis in having a unique combination of color pattern and scale characteristics including keeled subtibials, ventrals, subcaudals, dorsal tubercles, and forearm scales; 25–27 paravertebral tubercles; a median row of enlarged, keeled subcaudals; five or six precloacal, pore-bearing scales in males separated medially by one or two non-pore-bearing scales; 26–29 subdigital lamellae on the fourth toe; no dark, longitudinal gular markings or blotches; no dark shoulder patch enclosing a white to yellow ocellus; and having a yellow to white, prescapular crescent. Cnemaspis roticanai is the latest species in a growing list of new taxa being discovered from the Langkawi Archipelago.
