DiagnosisDiagnosis: A small member of the tabiltardieri group with legs olive brown longitudinally marked with series of black dots. Further dis tinguishable from labillardieri by its broken white dorsolateral line and from delli and gem mula by its heavily patterned back and lack of white midlateral stripe (Storr 1974: 92).

Description. Snout-vent length (mm): 33-58 (48.7). Length of appendages (% SVL): tail 168-191 (176); foreleg 21-29 (25.3); hindleg 33-44 (38.1). Nasals separated. Prefrontals separated, usu ally widely. Supraoculars 4, first 2 in contact with frontal. Supraciliaries 6-8 (7.2). Palpe brals 8-10 (8.8). Second loreal 1.1-1.4 (1.21) times as wide as high. Upper labials usually 7, occasionally 8. Ear lobules 3-6 (4.2), acute or subacute in adults, obtuse in juveniles, first or second usually largest. Nuchals 3 or 4 (3.5). Midbody scale rows 24-30 (26.7). Lamellae under fourth toe 21-25 (22.7), each with a dark obtuse keel or narrow callus. Dorsal ground colour olive grey flecked with black. An irregular black vertebral stripe oc casionally present. Broad black laterodorsal stripe from brow to tail, ragged edged and bearing a series of pale dots. White dorsolateral line from brow to tail, more or less broken into a series of short dashes. Black upper lateral zone bearing a series of white dots. Dark grey lower lateral zone irregularly flecked with whitish (Storr 1974: 92).
