Alinda fallax is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae, the door snails.
Description
The length of the shell varies between 14 mm and 22 mm, its diameter between 4 mm and 5.5 mm.
(Original description in Latin) The shell features a barely visible fissure and has a fusiform, swollen shape with small ribs, broad in form, and a brownish-horn color. The aperture is wide and rounded-pyriform, with a swollen spire and a crested base. The peristome is continuous, with a solitary, reflexed, reddish edge. The lower lamella is set apart, and there are two upper palatal folds, with the lower posterior fold being very short. A crescent-shaped fold is incomplete, and the columellar fold is slightly submerged. The area surrounding the umbilicus is hemispherical.
Distribution
This species occurs in Eastern and Southeastern Europe.
