Twenty-four specimens of Tadarida bemmeleni, collected in Cameroun in 1970, appear to be the first taken since the holotype was collected in 1875 from Liberia. Morphological comparisons with T. cistura from East Africa indicate that the two taxa are subspecies of the same species. Systematic relations, age, and sexual variation, as well as ecological notes, are provided. The facial features, caudal glands, palatal ridges, and cranial details are illustrated for the first time.
