Cochlostoma anomphale , uncommonly also ungabeled forest snail is a species of snail from the family of forest snails (Cochlostomatidae) in the order Architaenioglossa ("old band-tongue")that lives on land.
features
The right-hand wound case is 5.9 to 7.6 mm high and 2.8 to 3.6 mm wide. It has 7 to 8 well arched turns, which are separated from each other by a moderately deep seam. The last turn rises approximately at the height of the penultimate turn and is not expanded. Just before the mouth of the river, the last turn is significantly narrowed. The mouth edge is z. T. folded wide. In the spindle area it is modified right to acute angled ear-shaped. In old specimens it has grown together with the spindle envelope and is barely visible. The hem of the mouth is very narrow below and outside. There is a strong callus in the lower part of the mouth. In the neck area, the neck bulge is yellowish-white.
The housing is red-brown to horn-colored. In living animals it is often blue-gray and cloudy. There are two bands of spots on the lower turns and three bands of spots of indistinct light brown spots on the end turn. The surface is densely and regularly ornamented with fine ribs. The ribs become denser and finer on the end turn.
Similar species
The shell is smaller and slimmer than the shell of the small forest snail ( Cochlostoma septemspirale ).
Geographical distribution and habitat
The distribution area is limited to the Steiner Alps in the border area of Austria and Slovenia and the Julian Alps . The animals live on rocks and scree slopes, but also in mountain forests from around 550 m to 1200 m above sea level.
Taxonomy
The taxon was established in 1939 by Werner Boeckel as the subspecies Cochlostoma septemspirale anomphale . Today it is mostly interpreted as an independent species, and placed by Fauna Europaea to the subgenus Cochlostoma (Turritus) Westerlund, 1883.
