The Acanthosaura Tree Lizard shown here is considered an undescribed species. It occurs in Fraser's Hill, Peninsular Malaysia.

An adult specimen (left) was found clinging to the main trunk of a sapling, at the edge of primary forest at an elevation of around 1000 metres. Its body length measured 15 cm from snout to vent, but its tail length is unknown. It possesses a long spine extending above each eye socket, and small spines above the head and along the vertebral line. There are no spines on the back of the neck.

Adult body colour is yellow-brown to olive-green, patterned with numerous ocelli, or eye-like patterns. There is a dark band around the neck, and the tail is plain.

A smaller, juvenile specimen (right) was found inside a large house in the same general area of Fraser's Hill. This specimen differed to the adult in having a green head : the vibrancy of the green colour appeared dependant upon mood i.e. appearing bright green when not stressed, and brownish-green when stressed. The dark neck-band and ocelli of the juvenile are clearly similar to the adult patterning.

Nothing is known of the range of this lizard.
