Subgenus Cincinna Mörch, 1864

Type species: originally not specified. The authorship of this (sub-)generic name is usually attributed to Hübner (1810 — his letter was not published). However, Haszprunar (2014) argued that only Mörch (1864) first used the name Cincinna with a reliable diagnosis and thus made it available (more nomenclatural details see in Haszprunar, 2014). According to original classification (Mörch, 1864) the name Cincinna is subgenus of Valvata . Mörch (1864: 321–322) included in this taxon Valvata piscinalis, V. pusilla and V. antiqua though the type species was not specified. Most authors regarded Nerita piscinalis O. F. Müller, 1774 as the type species of Cincinna .
