Background and aims - The paleotropical genus Neuropeltis of the Convolvulaceae was recently treated in a synopsis for the African continent (Breteler 2010), counting nine species. This number is now enlarged by a new, overlooked, species from the South Province of Cameroon. Methods - Normal practices of herbarium taxonomy have been applied to study all herbarium material available, mainly from BR, K, P, and WAG. The distribution map has been produced using Arcview 324. Its collecting data are stored in the NHN (Nationaal Herbarium Nederland) database. Key results - The new species Neuropeltis eladii is described and illustrated, its distribution is mapped, and its conservation status assessed as Vulnerable (AOO) and Endangered (EOO). The key published earlier for the nine continental African species (Breteler 2010) is partly changed and extended to accommodate the new species.
