Etymology
The specific name africanus is given for the known distribution of the new species and its probable widespread distribution off the coast of west Africa.
Distribution
DNA sequence data and previously reported geographic distribution of R. africanus likely occurs from Mauritania to Angola, and the oceanic Islands of Cabo Verde and the Gulf of Guinea, although we have not examined specimens throughout this range.
