Fourteen specimens of a shallow-water, sand-inhabiting, polytentaculate holothuroid, dredged from Durban, South Africa, are new and described as Phyllophorus (Phyllophorella) rosetta sp. nov. The new species is distinct in possessing an abundance of rosettes in all parts of the body wall, often in combination with tables typical of those of the Phyllophorus subgenus Phyllophorella Heding & Panning, 1954. In the form of its tables and rosettes the new species appears to be closely related to P. (P) contractura Cherbonnier, 1988 from madagascar but differs from it in the form of its calcareous ring, the number of polian vesicles and the presence of rosettes throughout the body wall, instead of their restriction to the anal region. The presence of rosettes makes the new species, together with P. (P) contractura, a good intermediate between Phyllophorus and Lipotrapeza. The new species increases to nine the number of species now classified in the subgenus phyllophorella. All nine species are keyed.
