This distinctive species differs from all the other species of Beddomeia in having a small, elongate conic, almost pupiform shell with a weak columella fold and has a simple penis. In shell characters, this species is most similar to B. capensis, but differs from that taxon in its narrower, smaller shell, sculptured protoconch, thicker inner lip with a weak columellar swelling.
