Potamolithus
Genus of gastropods
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]
Distribution
Potamolithus is the only genus of the family Tateidae in South America. Distribution of Potamolithus includes Argentina (22 species, 11 species are endemic to Argentina),[7] Uruguay (17 species)[8] and Brazil.[3] Potamolithus is the largest genus (i.e. the one with the highest species richness) of recent freshwater snails in Argentina[7] and in Uruguay.[8]
