ABSTRACT: The species richness of the freshwater gastropods in Morocco is one of the highest in North Africa. Theodoxus sandsi sp.n. is a new gastropod from Morocco, which can be distinguished from its congeners by shell morphology and operculum criteria. The new species was found in the Middle Atlas massif, a cornerstone of the freshwater biodiversity in Morocco and North Africa in general. In addition, we discuss the taxonomic status of the problematic Theodoxus spp of Northern Africa.
KEY WORDS: Neritidae, freshwater biodiversity, Middle Atlas, Morocco; endemism.
