Identification. This species has a long, spear-shaped head and exceptionally long fangs. The back is streaked with lichen-green, black, and yellow. There is a lateral row of white spots at the juncture of the ventrals and the first dorsal scale row. The iris, infralabial, and gular scales are mottled, and the posterior part of the belly is heavily pigmented. A lacunolabial scale is present. Mid- body dorsal scale rows are usually 27 but range from 25– 29 ( Torres-Carvajal et al. 2020). In males, ventrals are 203–252, whereas in females there are 228–254. The prehensile tail has 70–91 undivided subcaudal scales in males and 66–80 in females.
