Auriculella perpusilla is a species of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks.

Auriculella perpusilla is incredibly small, most adult shells reaching a height of around 6 millimeters.

[2] Their thin shell has 5 strongly convex whorls with low spires and weakly reflected apertures.

In the past, Auriculella perpusilla inhabited wide parts of Eastern and North-Eastern Oahu throughout the Koolau Mountain Range.

[2] This land snail was prevalent in the wet, rain-abundant forest-mountain regions.
