Abida Pyrenaearia , little used and Pyrenean rye grain auger is a sort of chondrinidae (Chondrinidae) from the subordination of terrestrial snails (gastropod).
features
The spindle-shaped to cylindrical-spindle-shaped housing is 5.7 to 8.5 mm high and 2.1 to 2.7 mm wide. It has 8 to 9.5 turns that are slightly curved. The housing has its greatest width at the penultimate or last turn. The surface is finely and regularly striped; the housing is colored brown. The edge of the mouth has a strongly thickened white lip, but it is not shaped like a sill. The mouth edges are closed in the parietal area and z. T. even preferred up to 0.3 mm. The mouth reinforcement is formed in an angularis, which is occasionally connected to the spiral when a spiral is present; this is not always the case. The subangularis is developed as a nodule attached to the parietalis or absent entirely. In contrast, the parietalis is always clearly developed. The Columellaris is clearer than the Subcolumellaris and extends further forward. The superior palatalis, the inferior palatalis and the infrapalatalis are formed as double cusps and reach the lip of the mouth. The suprapalatalis can rarely be weakly developed or even absent (in high mountain forms). In addition, a weak suprapalatalis can be indicated. The obliquely flattened mouth is more or less higher than it is wide, and more or less keeled at the base. In the area of the infrapalatalis, the housing is more or less clearly indented, sometimes also notched. In the side view, the mouth edge is slightly bent down in the palatal area. The umbilicus is more or less clearly open (viewed vertically from below). The genitalia and radula are not known.
Similar species
Abida pyrenaearia is somewhat similar to Abida secale secale and Abida secale saxicola . However, it differs in the subangularis, which is never designed as a lamella, the almost always reduced suprapalatalis and the connection of the mouth edges in the parietal area. In addition, the first turns increase in width faster. In Abida attenuata the subangularis is designed differently. In Abida occidentalis , the double-humped palatal folds are shorter.
Geographical distribution and habitat
The distribution area of the species is mainly in the northern central Pyrenees on French territory; only two sites are on the Spanish side. A find near Hendaye in the French West Pyrenees is uncertain. The animals live above 1000 m to 2500 m above sea level on limestone rocks and limestone rubble.
Taxonomy
The taxon was established in 1831 by André Louis Gaspard Michaud as Pupa pyrenaearia . Edmund Gittenberger differentiates between two subspecies Abida pyrenaearia pyrenaearia (Michaud, 1831) and Abida pyrenaearia vergniesiana (Küster, 1850). Bas Kokshoorn & Gittenberger (2010) and in the following the Fauna Europaea, however, consider the latter taxon as a separate species. The Fauna Europaea has the following synonyms :
- Pupa aulusensis Fagot, 1880
- Pupa bipalatalis Westerlund, 1883
- Pupa boubeei Fagot & Nansouty, 1875
- Pupa clausiliformis Locard, 1894
- Pupa clausilioides Boubee, 1835
- Pupa curta Moquin-Tandon, 1843
- Pupa nansoutyi bassoon . 1880
- Pupa novemplicata Moquin-Tandon, 1843
- Clausilia pyrenaica Boubee, 1832
- Pupa saeva Westerlund, 1887
- Pupa transitus Boubee, 1833
Danger
According to the assessment of the International Union for Conservation of Nature and Natural Resources (IUCN), the species is not endangered despite its small distribution area.
