Taxonomy

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.

Anisus leucostoma may be a narrow-whorled morphotype of Anisus spirorbis.[5]

Shell description

The shell of this species is about 8 mm in maximum dimension, usually planispiral and tightly coiled, with a white rib in the aperture.[6]

Distribution

This species occurs in countries and islands including:

gollark: Deploy bee however.
gollark: Fascinating.
gollark: There are too many of them.
gollark: Approximately, yes, but facial muscles are hard.
gollark: I never actually worked out how to do smirks.
