DiagnosisDiagnosis: A large Lerista with one finger (terminating in wide flat scale), two toes, movable eyelid, two supraoculars and very weak to moderately strong pattern (four dark dorsal lines or rows of spots present or absent, and upper lateral stripe narrow and either solid, hollow or diffuse). Further differing from L. picturata in its shorter appendages, fewer subdigital lamellae, more greyish upper surface and whitish rather than yellow lower surface; it is also slightly smaller and more elongate.

Length of appendages etc. (% SVL): foreleg 0.5-1.5 (N 74, mean 1.0), hindleg 9.5-13.5 (N 71, mean 11.7), tail 70-98 (N 51, mean 82.0), snout to foreleg 20-27 (N 70, mean 23.9). Nasals in contact (N 53) or very narrowly separated (1). Prefrontals widely separated. Frontoparietals separated, much smaller than interparietal (N 52). Nuchals 1-6 (N 51, mean 3.8). Supraoculars two, first in contact with frontal (N 53). Supraoculars two, first in contact with frontal (N 53). Supraciliaries three with first much the largest (N 42), two with first much the largest (2) or four with first and third largest (7). Upper labials 6 (N 55). Midbody scale rows 18 (N 4), 20 (40),21 (1) or 22 (1). Lamellae under longer toe 7-10 (N 53, mean 8.8). (Storr 1991)
