DiagnosisDESCRIPTION: Size moderate (SVL in males to 28 mm, in females to 29 mm); dorsals large, acute, strongly keeled, imbricate, 24-31 axilla to groin; middorsal area of granular scales 1-3 rows wide; ventrals smooth, cycloid, 25-32 axilla to groin; dorsal caudal scales keeled, flat, imbricate, acute; ventral caudal scales cycloid, imbricate, no enlarged midventral row of scales; snout scales flat, smooth to weakly keeled, juxtaposed; 2 postnasals; 1-3 (mode 2) internasals; upper labials to mideye 2-3 (mode 3); gular scales keeled on sides of throat (occasionally keeled gulars extend across throat in a narrow band); midbody scales 41-49; escutcheon 3-6 x 22-25. Color pattern undergoes ontogenetic change: juvenile dorsum light brown, pattern of white crossbands edged with dark brown on neck, trunk, and tail (4-6 between axilla and groin), chin and venter white; with increasing age, dorsal crossbands fade or become indistinguishable from dorsal ground color; adult dorsal ground color varies from light to dark brown; dorsum may be uniform in color or speckled with dark scales (which may form vermiculations, especially on head); chin and venter white to light brown (from Schwartz & Henderson 1991: 493).
