R. nigrella DC. (Lamarck & De Candolle 1815), with which R. capensis auct. non Steph.: S. Amell (1952, 1963), is conspecific, is now also recognized from southern Africa. The thallus is brown marginally and dorsally and has shiny black scales with smooth margins at which coloured and hyaline cells alternate irregularly. Arnell's (1961) records of R. capensis Steph. from the Canary Islands are to be regarded as erroneous. R. capensis Steph. (Stephani in Brunnthaler 1913) is now placed in synonymy under R. limbata Bisch.
