The snail lives in cracks in rocks and walls, and is only active when it rains.

The aperture is oblique-oval descending from the third to the fourth whorl. Soft peristome with a brownish inner lip slightly reflected. Umbilicus is completely closed.
Distribution
The species is distributed along the northern Tramuntana Mountains in western Mallorca, cohabiting in many localities with A. graellsianus.
