Aegista chejuensis is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the family Camaenidae,[1] and was first described in 1908 by Henry Augustus Pilsbry and Yoichirō Hirase as Eulota (Aegista) chejuensis.[1][2]
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
Species of the genus, Aegista, occur on Korean Peninsula and in Japan.[3] However, this species is found only on the Korean peninsula,[4] in Jeollanam-do and on Jeju Island (in South Korea).[5]
