The pygmy toad genus    Poyntonophrynus    is endemic to southern Africa. The morphology of these small toads is conserved. They are usually dully colored, and are predominately adapted to arid conditions. During recent surveys in Angola we found    Poyntonophrynus    specimens that were not assignable to known species. Using an integrative approach, based on mitochondrial and nuclear DNA, morphology, osteology, biogeography and ecology, we identified three new lineages, and describe two of them as new species. All three lineages are closely related to    P.   pachnodes   , an Angolan endemic species, but they are geographically isolated from it. The new species are morphologically distinguishable, and are associated with two of the most important Angolan centers of endemism: the western escarpment and the central highlands. In order to get a more comprehensive understanding of the osteology of the genus, we also provide an osteological characterization of    P.   dombensis   , which was not available to date. Our findings i) increase the number of earless species in the genus    Poyntonophrynus   , ii) emphasize southwestern Africa as the cradle of diversification in this genus, iii) report the occurrence of    Poyntonophrynus    in humid environments, thus showing that these toads are ecologically more variable than previously thought, and iv) underline the importance of further biodiversity studies in Angolan centers of endemism.

Two new Poyntonophrynus species ( Anura : Bufonidae ) highlight the importance of Angolan centers of endemism
