Auristomia ignorata is a species of small sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.[1]
Description
The shell of Auristomia ignorata is small, typically reaching between 3 mm and 6 mm in length. Like many members of the genus Odostomia, the shell is ovate-conic, smooth, and usually white or translucent.
The protoconch is small and deeply immersed in the first of the teleoconch whorls. The teleoconch consists of several slightly convex whorls with a distinct suture. The aperture is oval, and the columella typically bears a single, small, often internal fold (tooth) which is a defining characteristic of the family Pyramidellidae.[2]
Taxonomy
The species was originally described by the Italian malacologist Marquis di Monterosato in 1917 as a subspecies of Odostomia bulimulus. While historically debated, current malacological databases such as the World Register of Marine Species (WoRMS) recognize it as a distinct species.[1]
Distribution
This species is primarily found in the Mediterranean Sea, specifically off the coasts of Italy and the surrounding European waters.[3] It is typically found in benthic habitats within the neritic zone.
