CommentHabitat. Very open, often undulating, stony plains, including areas of low rock outcrops with sparse chenopod ground cover and scattered Acacia overstorey. Through much of this area, a common component of the ground surface is silcrete gravel, its smooth surfaces and white to pale beige colouring contrasting with the underlying light to dark reddish clay.

Distribution: see map in Melville et al. 2019: 6 (Fig. 1: species C) 
EtymologyFrom fictilis, Latin adjective meaning fashioned from clay, as in porcelain or pottery, referring to the smooth scale surface and strongly contrasting colours of this lizard that match the equally contrasting silcrete and clay substrate on which they live.
