Abstract

<jats:p>A new species of endemic Cnemaspis is described from Gunung Jerai (also known as Kedah Peak) in the northwestern state of Kedah, Peninsular Malaysia. Cnemaspis harimau sp. nov. differs from all other Sundaland congeners except C. affinis, C. biocellata, C. kumpoli, C. mcguirei, C. pseudomcguirei, and C. shahruli in having a black shoulder patch with a white or yellow ocellus anteriorly located. It is most similar in appearance to its sister species, C. affinis, but differs by having a smaller maximum SVL of 40.7 mm vs. 50.8 mm; three vs. five postmentals; caudal tubercles encircling vs. not encircling tail; lateral caudal tubercles on anterior 25% of tail highly spinose and protruding vs. slightly spinose; and an overall higher degree of scale keeling (most prominent on the tail). The discovery of another montane endemic once again highlights the understudied nature of Peninsular Malaysia’s extensive mountain ranges.</jats:p>
