Tandy's sand frog (Tomopterna tandyi ) is a species of frog in the family Pyxicephalidae. It is found in South Africa, Botswana, Namibia, and south-western Angola, and from inland Tanzania and Kenya. It probably occurs more widely within and between these two disjunct areas. The specific name tandyi honours Robert Mills Tandy, an American biologist, herpetologist, and photographer and the collector of the type material.
The holotype, an adult male, measures 38 mm (1.5 in) in snout–vent length. The tympanum is visible. The fingers have no webbing whereas the toes are partially webbed. The dorsum has patches of grey or olive on lighter background. The dorsal warts are reddish brown with black marks. Many individuals have a dark interocular bar.
The male advertisement call is a series of continuously repeated notes. The call rate is about 7–8 notes per second and the emphasized frequency about 2700–2800 Hz. The call is distinct from T. delalandii and T. cryptotis.
