Diagnosis Rostral elongated; 9 supralabials, 3 supralabials in contact with the eye, the fourth, fifth and sixth; 10–11 infralabials; a single preocular; a single loreal scale; prenasal in contact with the second supralabial; a second pair of chinshields in contact with each other or separated by a row of scales; 182–197 ventrals; 125–145 subcaudals; tail length is 31 to 42% of total length; 15 +3 maxillary teeth. Color pattern on the first third of the body consists of mottled transverse patches becoming transverse bars on the neck; the back of the head is dark with pale longitudinal patch in the center; the rest of the body has pale vertebral line flanked by two dark dorsolateral lines; and two dark lateral lines.
