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 .
