REMARKS
The very limited material, represented by one specimen attached to the substrate, prevents identification to species level. The shell is thin, small, and subcircular in outline, with the apex situated subposteriorly. The external surface of the adult shell is covered with numerous, very indistinct ribs. A similar discinid with indistinct radial ornamentation was reported by d’Hondt (1987) from the
Réunion Island
region.
