Anisus leucostoma is a European species of small air-breathing freshwater snail, an aquatic pulmonate gastropod in the family Planorbidae, the ram's horn snails and their allies.
Taxonomy
[edit]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
[edit]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
[edit]This species occurs in countries and islands including:
- Czech Republic[7] – near threatened (NT)[8]
- Slovakia[7]
- Germany[9]
- British Isles: Great Britain, Ireland
