The species differs from all other known Leristain the following combination of character states: nasals in moderately broad contact; supraoculars three; loreal single; only one supraciliary (the posteriormostof the primitive Lerista series); forelimb absent; hindlimb monodactyl or stylar; midbody scale rows 16, and a distinct lateral brown stripe.|
Description. A small slender lizard with an obtusely angular snout and slightly countersunk lower jaw in lateral view; forelimbs lacking, hindlimb monodactyl or stylar, and a light sandy ground color with a dark brown lateral stripe. Rostral crescent-shaped,with an acute posteromedial projection partially separating the nasals; nasals large, in contact for approximately 30 percent of their maximum length; nostril situated anteriorly in nasal; frontonasal 1.8-2.3 times wider than long; prefrontals absent; frontal 1.1-1.3 times wider than long; frontoparietals distinct and separated; interparietal slightly wider than long, slightly to appreciably larger than a single frontoparietaland with parietal eye spot located just posterior of center; parietals in broad contact posterior to interparietal, each bordered along its posterolateraledge by primary temporal, upper secondary temporal and a nuchal; transversely enlarged nuchals on each side one or two; loreal single; presubocular present or absent; preocular single; supraoculars three, first two in contact with frontal; supraciliaries absent except for last just below suture between third supraocular and pretemporal (new term, see Fig. 1); postoculars two; lower eyelid movable, with clear window; primary temporal large, in broad contact with parietal; secondary temporals two, upper as large as primary or larger, lower much smaller than primary; external ear opening small (equal in size or smaller than nostril), even with or just below level of mouth; supralabials five, third below center of eye; infralabials five; mental 1.4-1.6 times wider than long; postmental 1.7-2.2 times wider than long, in contact with first two infralabials on each side; first pair of chin scales in broad contact; scales smooth, in 16 longitudinal rows at midbody; paravertebral scales 99113 (x̅ = 105.7, SD = 4.57, N = 7; counted from level of posterior edge of thighs forward to parietals); inner preanals overlap outer, medial pair much larger than neighboring scales; snout-vent length 4969 mm (N = 7); tail length at least 80 percent of SVL (tails of all specimens either broken or regenerated); maximum width of body approximately 5 percent of SVL; front limb absent; hind limb monodactyl with claw, or stylar without claw, two to five percent of SVL. Premaxillary teeth 7; presacral vertebrae 50-52 (x̅ = 50.1, N = 7); hind limbs with remnantof single digit (probably4th) comprising two phalanges or with all bones distal to proximal tarsals absent; sternum with two articulating ribs (from 9th and 10th presacral vertebrae); mesosternum absent, and parasternal chevrons 14 (N = 1, the type) (Greer 1983).
