Identification:
This snake species is small in size with a slender body that is not overly thick. The head is large. The dorsal (back) coloration is pale gray or pale yellowish-green, sometimes entirely white. The back features large, dark transverse bands or diamond-shaped markings that are separated by narrow spaces. These bands narrow or disappear towards the belly. The ventral (belly) coloration is pale yellow or white. The head is yellowish-green.
The dorsal scales on the posterior part of the body are hexagonal, numbering approximately 33-35 rows. Females typically have a higher number of scale rows than males. The scales often possess short ridges or raised bumps, which are either interleaved or just slightly overlapping. The ventral scales are quite distinct, being twice as wide as the surrounding scales. These scales broaden towards the anterior (front) of the body and narrow towards the posterior (back).
