Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=1369559 on 2024-05-14 and was first described in 1908 by Henry Augustus Pilsbry and Yoichirō Hirase as Eulota (Aegista) chejuensis.

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 - whorls. The aperture appears oblique, with a thin, expanded outer lip. The outer and basal margins delicately curl inward.

Distribution Species of the genus, Aegista, occur on Korean Peninsula and in Japan.Kimura, K., Chiba, S. & Pak, J. H. (2023). Molecular investigation on diversity of the land snail genus Aegista (Gastropoda, Camaenidae) in South Korea. Biodiversity Data Journal. 11: e96800. However, this species is found only on the Korean Peninsula, in Jeollanam-do and on Jeju Island (in South Korea).
