Description & Biology

The length of the shell attains 8.5 mm, its diameter 5 mm

(Original description in French) The shell is solid, imperforate, and possesses an oval-conic shape with a sinistral coil. It is distinctly striated in a longitudinal direction. There are six whorls in total, which are plano-convex in profile, separated by a well-marked suture that leads to an obtuse summit.

The aperture is vertical and subauriform (somewhat ear-shaped). The peristome is very thick and double-layered, while the parietal lamella is relatively thin. At the extreme upper portion of the columella, there is a thick, strongly twisted fold.

In terms of coloration, the shell is a light purplish-white, except at the base, which is a burnt brown. The shell is covered by a brown epidermis that detaches easily. Both the peristome and the interior of the aperture are a light brown hue. [3]

Auriculella ambustahas a white shell with possible markings. [4] They eat fungi and bacteria from leaves.

Distribution

This species is endemic to the Hawaiian Islands.

Habitat

They are found in the Waianae mountains in west Oahu. [5] [6]
