Norelona pyrenaica is the type species of the genus Norelona.

Shell description[edit]

The shell is narrowly umbilicated, flattened above, thin, pellucid, olivaceous corneous. The shell has 4½[2] whorls, that are rather flattened. The last whorl is not descending. The peristome is acute, reflected, white-lipped.[3]

The width of the shell is 17-21 mm. The height of the shell is 9-11 mm.[2]


This species of snail makes and uses love darts.[4] (Image of reproductive system.)


This species is endemic to the eastern Pyrenees, France.[5] (map of distribution, map 2)

It is also known from Spain since 2007.[6]
