Neotropical sunbeam snakes have a prominently upturned snout. The scales on top of the head are large, whereas the
scales on the body are smaller, smooth, and slightly iridescent. Pelvic spurs are present in both sexes but usually are not visible in females. Individuals are uniformly brown or have a white or cream belly sharply set off from the dark dorsum. In addition to this variation in body coloration, many individuals have small, highly irregular white blotches.
