The material includes a new species of dwarf toad, Bufo grandisonae, which is described. It is most similar to Bufo dombensis, of which a redescription is given. A northern extension in the known range of Phrynomerus annectens is recorded. Keywords: Amphibia, Angola, Bufo grandisonae, Bufonidae, Distribution, taxonomy.
