Delma haroldi Storr, 1987 Delma butleri, also known commonly as Butler's legless lizard, Butler's scalyfoot, the spinifex snake-lizard, and the unbanded delma, is a species of lizard in the family Pygopodidae.

[2] The specific name, butleri, is in honor of Australian naturalist William Henry "Harry" Butler.

[3] The preferred natural habitat of D. butleri is grassland.

[1] Populations of butleri are broadly separated by the hyperarid center of Australia across the Simpson Strzelecki Dunefields, Stony Plains, Great Victoria Desert, Finke, MacDonnell Ranges, and Nullarbor bioregions- most likely due to recent (<10 Mya) aridification.

[4] Limbless and small for its genus, D. butleri may attain a snout-to-vent length (SVL) of 9 cm (3.5 in), with a tail length of three times SVL.
