This harmless snake species reaches approximately 1 meter in length. The head is distinct from the neck. The reddish-brown back features two thin black lines running from behind the eyes to the tip of the tail. A slightly darker black marking runs down the center of the head, from near the snout to the top of the head. A row of large, reddish-brown spots with black borders runs along the back. These spots become progressively fainter towards the posterior end of the body. The ventral side is pale yellow. Females are slightly larger than males.
