Anisus septemgyratus is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.

Taxonomy

Glöer (2002)[2] considered Anisus septemgyratus (Rossmässler, 1835) as a junior synonym of Anisus leucostoma (Millet, 1813). Later Glöer & Meier-Brook (2008)[3] used name Anisus septemgyratus again.

Horsák et al. (2013)[4] consider Anisus calculiformis (Sandberger, 1874) as a synonym of Anisus septemgyratus.

Distribution

  • Czech Republic[5][4] – in Moravia, critically endangered (CR)[6]
