Aegista tumida is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae.
- Subspecies
- Aegista tumida cavata (Pilsbry, 1902)
- Aegista tumida tumida (Gude, 1901)
Description
The diameter of the shell attains 15.5 mm, its height 13.5 mm.
(Original description) This species differs from the type in several key aspects: it is darker in color, has more tumid whorls, a higher spire, and a wider umbilicus. Additionally, the cuticular lamellae are much less pronounced. One specimen exhibits a pale peripheral band, giving the shell a strong resemblance to Aegista oculus (L. Pfeiffer, 1850).
Distribution
This snail occurs on Honshu Island, Japan.
