Synonyms

• Cincinna Hübner, 1810 · accepted, alternate representation (Cincinna is treated as subgenus of Valvata)
• Cincinna (Atropidina) Lindholm, 1906 (subgenus-genus combination invalid; Atropidina is considered a junior synonym of Tropidina or Cincinna (depending on source); to avoid problems we refer to Valvata only)
• Cincinna (Cincinna) Hübner, 1810 (Cincinna is treated as subgenus of Valvata)
• Gyrorbis Fitzinger, 1833 (junior synonym (?))
• Planorbis (Gyrorbis) Fitzinger, 1833 (junior synonym (?))
• Valvata (Atropidina) Lindholm, 1906 (type species of Atropidina (Valvata pulchella Studer, 1789) is considered a junior synonym of V. (Cincinna) piscinalis; however, FE ranks Atropidina as synonym of Tropidina (type species: V. macrostoma Mörch, 1864); to avoid problems we refer to Valvata)
