Sand frogs of the African genus Tomopterna Dumeril and Bibron, 1841 comprise seven described cryptic species. In this paper we describe a new species from Khorixas, north west Namibia. It is considered a distinct form based on the advertisement call, morphology and mitochondrial DNA sequences.

A new species of sand frog in the genus Tomopterna is described from the highlands of south-central Tanzania. It is distinguished from the other three species of sand frogs in East Africa on the basis of a low-pitched advertisement call, more webbing, and differences in morphology and colour pattern. It is genetically different from eight other species of sandfrogs.

The study describes for the first time the larva of the Red Sand Frog, Tomopterna luganga. The description is based on colour photographs of living specimens, preserved specimens, and SEM images of the oral field and internal oral features. Larval stages were obtained from captive breeding experiments. The identity of the species was verified by DNA matching with the holotype and paratypes. Tomopterna luganga tadpoles were very similar to other described larvae within the genus. The Labial Tooth Row Formula 4(2-4)/3(1) of T. luganga distinguishes the species from some of its congeners. However, the currently available data does not allow the development of a reliable determination key for the tadpoles of Tomopterna species.
