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

Description

[edit]

The diameter of the shell attains 6.3 mm (0.25 in), its height 3 mm (0.12 in).

The shell is distinctly umbilicate, convex above and below, with a broad, rounded edge around the periphery. The shell is adorned in a light yellowish-brown hue. Its surface is adorned with a dense layer of fine, short cuticular scales, easily removed with a gentle rub. It contains approximately five whorls, each gradually expanding and convex, delineated by an impressed suture. The body whorl widens notably, remaining convex on its underside without a noticeable descent towards the front. The aperture takes on a broad crescent shape and is slightly tilted. The peristome is delicately thickened and narrowly expanded, slightly reflexed.[2]

Distribution

[edit]

This species occurs in Japan.
