Elona quimperiana, common name the escargot de Quimper ("Quimper snail"), is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Elonidae.

Elona is a monotypic genus, i.e. it contains only one species, Elona quimperiana. The specific name comes from the city of Quimper in France.[4]

This snail is mentioned in annexes II and IV of the Habitats Directive.

Original description

Elona quimperiana was originally described (under the name Helix quimperiana) by André Étienne d'Audebert de Férussac in 1821.[3]

Férussac's original text (the type description) reads in the French language as follows:

Which means in English:

"Habitat: Margin of Briec (Briec-de-l'Odet) near Quimper in Brittany. It was found by Messieurs De Kermovan and Bonnemaison."

Shell description

The shell is umbilicate and planorboid in shape. The spire is slightly concave. The periphery is broadly rounded, corneous with a few varicoid white stripes.[5] The shell has five or six whorls.[6]

The aperture is lunar and slightly oblique. The lip is white, expanded above, reflexed below, with the ends distant.[5]

The width of the shell is 20–30 mm. The height of the shell is 10–12 mm.[6]

Anatomy

The jaw has 11-16 narrow ribs.[5]

The anatomy of Elona quimperiana was described in detail by Alfred Moquin-Tandon already in 1855-1856[7] and later by Gittenberger (1979).[8]

Drawing of reproductive system by Gittenberger 1979.)

Distribution

This species is found in France and Spain.

The Lusitanian snail Elona quimperiana has a remarkably disjunct distribution, limited to northwestern France (Brittany), northwestern Spain and the Basque Country.[4]

Habitat

This species lives in temperate and humid deciduous forests.[4]

Life cycle

The life span is 2–3 years.[9]

Feeding habits

This species of snail feeds on mycelia found on rotten, dead stumps (principally oak). Occasionally, it is coprophagous and necrophagous. Like many other terrestrial gastropods, Elona quimperiana has a relatively limited dispersal capacity and probably survived during the Quaternary glaciations through significant fluctuations in its distribution area, just as its deciduous forest habitat did.[4]
