Erythrotrichia platyphylla is described as new to science from the South African south coast; it is a relatively broad foliaceous species with a uniseriate stipe and a single endophytic basal cell. Its taxonomic relationships to other (foliaceous) Erythrotrichia species are discussed. Erythrocladia irregularis is recorded from the central Namibian coast, a first record for temperate southern Africa. An overview is given of the distribution of all members of the family Erythropeltidaceae now recognised in this area (nine species in five genera): the warm temperate south coast appears to be somewhat richer in species than the cool temperate west coast, a situation that reflects both the general trend in southern African marine algal biodiversity and the general pattern of geographical distribution of the Erythropeltidaceae world wide.
