Head scales are large, the specimen presents four rows of snout scales of sub-equal size between the internasal and the anterior pair of frontal scales, there are four moderately-sized parietal scales and the most lateral scales are smaller than the median scales, two rows of post parietal scales are present, there is no enlarged lateral post-parietal scale, there are three internasal scales, there are four lorilabial scales anterior to the first lorilabial contacting the elongated sub-ocular scale, the cephalic scales lack ridges, the temporal scales are of sub-equal size and no elongated temporal scales are present, the lateral nuchal scales are smaller than surrounding body scales, the lateral body scales are the same size as dorsal and ventral scales, a prominent middorsal body crest formed by overlapping scales is present, the dorsal crest (occiput to vent) is composed of 53 scales, the tricarnate scales at the base of the first and second toes grow into comb-like fringes but are not prominent, the venter is dull and patternless, there is no scapular patch, no suprascapular blotches, no facial band, and the base of tail is laterally compressed.
