Original taxon: Neritina valentina.
The shell differs from that of baeticus by its spire, always high, and by its two bulgy keels that cover the whole surface of the last whorl. The apex, globose, prominent, and the fat columellar callus recall those of the moroccan poppei. Sculpture: numerous prosocline commarginal growth marks.
