They are more commonly known as Dwarf Sand Geckos, I believe. Im pretty sure we used to get something very similar when I lived in Saudi. I think there are about three or so species availbale for hobbyists, of Stenodactylus genus. They are S. doriae, S. petrii and S. sthenodactylus These are quite small, and are used to desert conditions. They are nocturnal, and they arent really suitable for rough handling as they are very fragile and their tail's do come off easily. From what I've read/seen, a temperature range from 75°F to 85°F (24°C to 29°C) during the day works well. Additionally, offer a small hot spot that reaches between 95°F and 100°F (35°C and 38°C). At night, the ambient temperature in the cage can fall to between 65°F and 75°F (18°C and 24°C). I think that incandescent light bulbs work best to achieve these temperatures, however heat pads or heat tape may be used instead. Avoid hot rocks and other dangerous heating devices. Established dwarf sand geckos are hardy in regards to the temperature at which they are kept, and cope well with temperatures temporarily outside of their ideal temperature range.
Hope this has helped!
