The high diaper snail ( Columella columella ) is a type of snail of the family of the diaper snail (Vertiginidae) from the suborder of the terrestrial lung snail (Stylommatophora).
features
The case is 2.7 to 3.3 mm high and 1.3 to 1.5 mm wide. It is almost cylindrical with up to 7½ slightly arched passages. The first three turns increase more rapidly, the apex is therefore somewhat flatter, the outer lines of the following whorls are almost parallel. The seam is deep and the last passage noticeably expanded. The mouth is egg-shaped, significantly higher than it is wide and barely flattened at the top. The rim of the mouth is simple and fragile, and bent over in the spindle area. The needle-shaped navel is therefore almost completely covered. The housing is dull green to horn brown and translucent. The skin is thin, the shiny surface shows only weak, irregular growth stripes.
Similar species
The shell of the tall diaper snail is very similar to the shell of the toothless diaper snail ( Columella edentula ), but is somewhat smaller and has fewer whorls.
Geographical distribution and habitat
The species occurs in the mountains of northern Scandinavia (to the north of the Arctic Circle), in northern Russia (61-69 ° N), in the Swiss Alps, rarely in the Bavarian and Austrian Alps, in the Polish and Slovak western Carpathians ( Tatra Mountains , Little Fatra , Great Fatra ) as well as in the Crimea. Larisa A. Prozorova and Viktoria V. Berezhok also reported the species in 2004 from the island of Sakhalin ( Russian Far East ).
It prefers boggy meadows and wet, subarctic forests. In the Alps and Carpathians it occurs on alpine meadows on calcareous soil. In Switzerland the occurrence is limited to the altitude range from about 1000 to 2900 m.
Taxonomy
The taxon was first described by Georg von Martens in 1830 as Pupa Columella . He noted the name Benz after the name Columella . Benz was the “Bergraths Secretair” and collector of the material. Which information comes from him is not entirely clear, since v. Martens ascribes the species name to him, Benz must probably be considered the author of the taxon according to the International Rules for Zoological Nomenclature . F. Welter Schultes writes in Animal Base that the name of the alleged author Benz does not appear in the correspondence sheet. But that is not correct, because Benz is listed in the table of contents with a reference to page 171 (= original description of Columella columella ).
Danger
The species is very rare in Germany and is therefore classified in category R. Overall, in terms of the area of distribution, the high nappy snail is not endangered according to the assessment of the International Union for Conservation of Nature and Natural Resources (IUCN).
