Glöer (2002)[3] considered Anisus septemgyratus (Rossmässler, 1835) as a junior synonym of Anisus leucostoma (Millet, 1813). Later Glöer & Meier-Brook (2008)[4] used name Anisus septemgyratus again.

Horsák et al. (2013)[5] consider Anisus calculiformis (Sandberger, 1874) as a synonym of Anisus septemgyratus.
