Alycaeus is a genus of small land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Alycaeidae.

Description

(Original description) The operculum is horny with multiple whorls. The conical shell has a regular spire. The body whorl is distorted and compressed and significantly contracted before the aperture. The aperture is circular, with a regularly reflexed peristome.

The protoconch sculpture is smooth to obliquely striated. The diameter of the shell varies between 8 mm and 15 mm. The central tooth of the radula consists of five broad cusps with the central cusp blunt.

Distribution
