The background colour is a pale reddish brown with a close covering of yellow or white specks. There are a series of symmetrical white patches on the body which are scattered with large yellow spots. It is somewhat similar externally to T. brunnea but in that species the background colour is a uniform dark brown and there are no yellow spots in the large white patches.They differ considerably in tooth morphology.
