Anisus leucostoma
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
Glöer (2002)[1] considered Anisus septemgyratus (Rossmässler, 1835) as a junior synonym of Anisus leucostoma (Millet, 1813). Later Glöer & Meier-Brook (2008)[2] used name Anisus septemgyratus again.
Anisus leucostoma may be a narrow-whorled morphotype of Anisus spirorbis.[3]
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.[4]
