Auriculella crassula is a species of air-breathing tropical land snails, terrestrial pulmonate gastropod mollusks in the family Achatinellidae. ^[2]

Description

The length of the shell attains 7.5 mm, its diameter 4 mm

(Original description in Latin) The shell is typically sinistral (left-handed), though it is occasionally found to be dextral (right-handed). It possesses an ovate-conic shape and a solid structure. The shell is distinctly perforate and lacks a glossy luster, exhibiting a pale brown coloration.

There are six and a half whorls, which are nearly flat in profile. The aperture is a dull, dirty white on the interior. The peristome is thickened and slightly dilated at its base; it is notably fortified by a small, prominent tubercle located at the junction where it meets the body whorl. Finally, the columella is thick and somewhat reflected, though it lacks any visible fold. ^[3]

Distribution

This species is endemic to Hawaii.
