The stripe is broken into two rectangular orange blotches behind eye which are surrounded by black. Mid-body the stripe is dark brown to black. The stripe finally grades into golden yellow irregular blotches onto the caudal peduncle. Ventrally, the head and belly have alternating small and large golden blotches suffused with orange near the ventral midline. Dorsum rosy red to salmon with pale blotches.
