[Glöer P. (2002). ''Die Süßwassergastropoden Nord- und Mitteleuropas''. Die Tierwelt Deutschlands, ConchBooks, Hackenheim, 326 pp., , page 190-194.] recognized four subgenera ''Bithynia'', ''Codiella'', ''Neumayria'' and ''Parafossarulus'' within European species. He reassigned two European extinct species of ''
Parafossarulus'' into a subgenus of the genus ''Bithynia'', but the genus ''Parafossarulus'' is generally accepted for the Asian species.
The subgenus ''Digoniostoma'' is also recognized for Asian species.
