A reddish-brown reptile growing to 8 cm with a dark brown/black streak from below eye to ear, dark vertical patch on the side of the neck, orange-brown tail with four broad black bands, pale orange belly, distinct nuchal (nape of the neck) series of slightly enlarged scales and clusters of scales in skinfolds on the neck (Cogger 2000).

Occurs within an area of approximately 35 km&#178 around the Gascoyne River on Yinnietharra Station, east of Carnarvon, WA (Cogger et al. 1993). Only known from two localities within this area, 5 km east, and 25 km south-west of Yinnietharra (Storr 1981; Wilson & Knowles, 1988; Cogger et al. 1993).

First described as Amphibolurus yinnietharra (Storr 1981).

Generally occurs in tall open shrubland. Inhabits granite outcrops separated by stony flats supporting sparse Acacia shrubs. Appears to be restricted to rocks of one origin - Archean gneissic biotite granites and granodiorite - whilst nearby outcrops of Early Proterozoic migmatite are inhabited by a different species, Ctenophorus caudicinctus (Cogger et al. 1993). Basks on low rocks and Acacia limbs (Wilson & Knowles 1988). One specimen was observed running across gibber flats between granite outcrops and climbing stunted Acacias (Storr 1981). Individuals have been captured sheltering beneath exfoliating granite, from burrows under granite boulders and in a hollow Acacia log (Storr 1981; Wilson & Knowles 1988).

Extremely wary - dashes for cover when approached. Males lash their tails in the presence of females or other males (Wilson & Knowles 1988).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
