The red-brown cylinder nappy snail ( Truncatellina monodon ), also called single-toothed cylinder nappy snail or brown cylinder nappy snail , is a type of snail of the family of nappy snails (Vertiginidae) from the suborder of land snails (Stylommatophora).
features
The cylindrical housing of the red-brown cylinder diaper snail is 2.2 to 2.3 mm high and 0.9 mm wide. It has six slightly arched turns, which are separated from each other by a flat seam. The housing is colored (red) brown, the surface is covered with fine, close-packed and somewhat irregular growth strips. The edge of the mouth is slightly thickened. Three "teeth" protrude into the mouth, but only one of them is easily visible (name monodon = single tooth). The parietal tooth is clearly visible in direct supervision of the mouth. The columellar tooth, on the other hand, can only be seen in an oblique view. The large palatal tooth sits deep in the mouth and is not visible from the outside.
Similar species
The coils of this species are slightly less arched than in the light cylinder diaper snail ( Truncatellina claustralis (Gredler, 1856)), the bulging cylinder diaper snail ( Truncatellina costulata (Nilsson, 1823)) and the cylinder diaper snail ( Truncatellina cylindrica (A. Férussac, 1807) ). It is also less ornamented or almost smooth in contrast to the other Truncatellina species mentioned.
Geographical distribution and habitat
The area of the species is strongly fragmented and extends from Eastern France ( Savoy ), Switzerland ( Bernese Oberland , Graubünden , Vaud ), the northern Alpine foothills, the Bavarian Alps , Austria (here with a northern and southern area), northern Italy ( South Tyrol ) to Slovenia , Croatia and Bosnia and Herzegovina .
The species lives on dry meadows on limestone soil or limestone rubble.
Taxonomy
The taxon was first described by Friedrich Held in 1837 as Vertigo monodon . The fauna Europaea has only one synonym : Pupa striata Gredler, 1856.
Danger
In Germany the species is extremely rare and is therefore classified in category R. In terms of the entire range, the species is not endangered according to the International Union for Conservation of Nature and Natural Resources (IUCN).
