Potamolithus is a genus of small freshwater snails that have an operculum, aquatic gastropod mollusks in the family Tateidae.[2][3][4]

Potamolithus was traditionally classified within the Hydrobiidae.[2] However, anatomical study of Potamolithus by Davis & Pons da Silva (1984)[2] showed its relationship with Lithoglyphus,[2] and it is then placed within the family Lithoglyphidae.

The first appearance of the name Potamolithus was in November 1896 as a nomen nudum (a bare name with no description or illustration).[5][6] The genus was formally defined by Pilsbry in December 1896.[1]
