Aegista chejuensis is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the family Camaenidae. ^[1]

Description

The diameter of the shell attains 10.5 mm.

The shell bears a striking resemblance to Aegista mimula , adopting a similar shape. Its complexion is a subtle pale brown, adorned with a glossy finish, and etched with delicate, irregular growth lines. Upon closer inspection, faint spiral lines adorn the base, while the overall cuticle maintains a smooth texture. The shell contains 6 - 6⅓ whorls. The aperture appears oblique, with a thin, expanded outer lip. The outer and basal margins delicately curl inward. ^[2]

Distribution

This species occurs on Jeju Island, Japan and Korea ^[3]
