Aegista catostoma 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 16 mm.

The shell exhibits a prominent wide umbilicus and is characterized by its thin, striated, and corneous texture. The shell contains 7 convex whorls, each gradually expanding in size. The body whorl is rounded and abruptly descends towards the front, featuring a subtle constriction behind the aperture and a compressed area around the umbilicus. The peristome is sinuously curved and reflects inward, displaying a superior internal projection, along with basal thickenings that are somewhat dentiform in nature.[2]

Distribution

[edit]

This species occurs in Myanmar, India, China.
