The belly is orange or red, with a light band between the belly and flanks. Both the belly and throat may be spotted. The male is very similar to the female, although the female's cloacal swelling is slightly pointed. The male also has slight dorsolateral ridges, and a small crest on the tail. No crest is present on the male's body.
