Based on the results of morphological and molecular phylogenetic analyses of newly collected material, we reinstate the
soft coral genus Eunephthya Verrill, 1869 for a group of species endemic to South Africa. Eunephthya is morphologically
and phylogenetically distinct from the zooxanthellate, tropical genus Capnella Gray, 1869 with which it had been synonymized.
In Eunephthya the polyp sclerites include unilaterally spinose or leaf spindles, and the sclerites of the stalk surface
and interior (when present) are small radiates and spheroids. In contrast, C. imbricata, the type species of Capnella, has
leaf clubs and leaf-capstans in the polyps and stalk surface, and large ovals and irregular forms in the interior. We describe
four new species of Eunephthya from Algoa Bay, South Africa—E. celata, E. ericius, E. granulata, and E. shirleyae—
and propose a new combination, E. susanae.
