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

Description

Auriculella perpusilla is incredibly small, most adult shells reaching a height of around 6 millimeters. Their thin shell has 5 strongly convex whorls with low spires and weakly reflected apertures.

Distribution and habitat

This species is endemic to the island of Oahu, Hawaii. In the past, Auriculella perpusilla inhabited wide parts of Eastern and North-Eastern Oahu throughout the Koolau Mountain Range. This land snail was prevalent in the wet, rain-abundant forest-mountain regions. Today, this species has been only recorded in a specific mountain region near Honolulu.
