Alycaeus is a genus of small land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Alycaeidae. ^[1]

Description

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. ^[3]
