| Diagnosis | Diagnosis (genus): A genus consisting of large agamid lizards in the subfamily Amphibolurinae, with exposed tympanum, gular scales smooth to weakly keeled, ventral scales weakly to strongly keeled. Stoutly built with moderately long legs and tail. Broad white stripe on the upper and lower lips, extending along the full extent of the jaw, pale stripe from behind the eye to the top of the ear, which is cream, white, grey or yellow in life. This pale stripe is well defined ventrally and dorsally by a row of darkly pigmented scales (fig. 6). Heterogenous scales on the back both at the midline and doroslaterally, associated with a weak to prominent row of enlarged, strongly keeled scales. Colour patterns of grey, brown, rust-brown and black. Well- developed nuchal crest continuous with the enlarged row of vertebral scales. Broad pale dorsolateral stripes, which may extend from top of ear or back of head to hips. Dorsolateral stripes are not continuous with the pale lip stripes. On the back, dorsolateral stripes may be intersected by wedges of brown or grey. Preanal pores 3–6; femoral pores 2–8 (Melville et al. 2018: 53) |
