| Diagnosis | DESCRIPTION: Size small (SVL in males to 42 mm, in females to 40 mm); limbs very short; 2-6 rows of loreals; scales between supraorbitals 2-5 (mode 3); 2-6 (mode 4) scales between interparietal and supraorbital semicircles; 6-10 (mode 9) postrostrals; 4-6 (mode 4) postmentals; no enlarged postanal scales in males; supraciliary scales granular; only 2 (posterior) differentiated canthals; head scales smooth; frontal depression shallow; middorsal scales smooth, fiat, not larger than flank scales; ventrals larger than dorsals, smooth, cycloid, juxtaposed, in transverse rows; dewlap large, present in both sexes, inset, all scales granular, smaller than throat scales, much smaller than ventrals, edge scales especially small, lateral scales of dewlap small but well developed in well-separated rows (males), or weakly developed to almost absent (females); limb and supradigital scales smooth; tail round, without crest; verticils indistinct with about 11 granules dorsally and 5 keeled scales below per verticil. Dorsum: (1) unicolor-gray through olive-brown, olive, yellow-green, to dirty orange; pattern elements (see below) minimal, but lumbar spot(s) usually present; axillary and inguinal areas dull to bright yellow; yellow edge to lumbar spot; usually green during day and gray or brown at night; (2) lichenate-pattern boldly developed and black or dark gray, ground color off-white to very light gray; (3) intermediate-ground color as above, but with pattern represented by fragments, moderately or poorly developed, or reticulate; pattern elements: a dark cephalic figure or interocular triangle, solid or hollow; dark, radiating eye-lines; 4 zones of transverse banding on body (scapular, dorsal, lumbar, sacral), manifested as either very hazy, indistinct, dark bands or as bands with sharply defined, sinuous, dark anterior edge and posteriorly fading zone of dark pigment; a yellow lumbar spot (often paired) in lumbar band (resembling eye-spots-is this to warn off potential predators, or is it for intraspecific recognition?) the most constant pattern feature; a fine, reticulum of dark lines, appearing as faint small ocelli; venter pale, frequently with some stippling and a distinct but irregular zone of juncture with dorsal color; transverse body bands continue onto tail as small, dark chevrons; dewlap pinkish gray or cream, posterior edge rusty (no sexual dichromatism) (Schwartz & Henderson 1991: 306). |
