DESCRIPTION. Based on five specimens (four adults and one subadult). Measurements are given for four adults only. Scalation and osteology for all specimens unless otherwise stated.
Measurements: maximum SVL 41 mm; distance from axilla to groin 61.0-63.5% of SVL (
Scalation: prefrontals present, very small and widely separated; supraciliaries 7 (50%) or 8 (40%), rarely 6; ear opening positioned two scales posterior to lower secondary temporal; body scales with 3-4 fine striations, midbody scale rows 22-24 (
Osteology: presacral vertebrae 29-30 (
Colouration: dorsal and lateral colour mid to dark brown with numerous small, scattered, pale spots on head, and faint dark markings along dorsolateral and vertebral axis. Dark dorsolateral markings poorly defined, extending from back of eye to level of hindlimbs, breaking up and becoming ill defined along tail. Ventral surface pale with scattered brown markings at ventrolateral edge, and irregular brown markings to throat.
Subadult colouration (Single specimen) markedly two-toned, with a light dorsal and darker lateral surface. Dorsal surface mid brown with dark vertebral markings forming a faint but continuous line from nape to base of tail. Lateral surface dark brown, unmarked. Dorsal and lateral surfaces defined by a dark (notably darker than lateral colour) dorsolateral stripe (inflected over tympanic region) (Sadlier et al. 2002: 241).
Distribution: see map in SADLIER et al. 2014: 54.
