Auriculella perpusilla is a species of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks.[3]
This species is endemic to Hawaii.
Description
[edit](Original description in Latin) The shell is small, left-handed (sinistral), and shortly ovate-conic in shape. It is perforated, fragile, and horn-colored. There are 5 slightly convex whorls separated by a simple suture. The aperture is subcircular, and the parietal wall features a thin layer (lamina). The peristome is thin and slightly dilated, while the columella is not folded and is somewhat reflected.[4]
Auriculella perpusilla is incredibly small, most adult shells reaching a height of around 6 millimeters.[5]
Their thin shell has 5 strongly convex whorls with low spires and weakly reflected apertures.[5]
Distribution and habitat
[edit]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.[5] 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.[5]
