DistributionAustralia (Gawler, Flinders and Mt Lofty Ranges of South Australia, extending eastwards into SC New South Wales and SW to the coast of the Great Australian Bight as far west as Ceduna and the Nuyts Archipelago)

Type locality: “Mt Colley”, Cocoparra National Park, near Griffith, N.S.W., Australia.

Type locality [annettae]: Willandra National Park, near Hillston, N.S.W.

CommentDiagnosis. A moderate sized Gehyra (max. Snout-vent length (SVL) 59 mm) with divided subdigital lamellae, two or three pairs of enlarged chin shields, a dorsal pattern combining small pale spots and irregular, dark spots or short wavy lines, and a diploid chromosome number of 44. Most similar to G. nana, from which it differs in grey to brown rather than rufous dorsal colouring with more prominent black flecks and lines. Gehyra lazelli is sympatric or parapatric with two other species, G. variegata (2n=40a form) and G. purpurascens. Distinguished from G. variegata by fine spotted rather than ladder-like colour pattern, the white spots not margining the dark markings, slightly larger size, higher preanal pore counts and (in syntopy) rockdwelling rather than arboreal habits. Distinguished from G. purpurascens (2n=40c) by bolder spotted pattern, with larger black flecks and wavy lines and numerous white spots present in adults, and smaller size (max. SVL of G. purpurascens 65 mm).
