Abstract
    Several specimens of a phyllophorid holothuroid collected from off the KwaZulu-Natal coast, Republic of South Africa, represent a species new to science. In the structure of the calcareous ring and the absence of tables from the body wall it resembles Neothyonidium magnum and N. arthroprocessumo. In all three species the posterior processes of the calcareous ring are distally joined. Hence, they do not correspond with the diagnosis of Neothyonidium as defined by its type species, N. hawaiense, and are now assembled in the new genus Massiniumo The new species is described as Massinium maculosumo The three species are keyed and a distribution map is provided.
