Tiberia Explained

Tiberia is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.^[1] Tiberia is the only genus in the tribe Tiberiini.

Taxonomy

According to Schander, Van Aartsen & Corgan (1999) the subfamily Tiberiinae contains a single genus, Tiberia.^[2]

Tiberiinae was one of eleven recognised subfamilies in the family Pyramidellidae according to the taxonomy of Ponder & Lindberg (1997).^[3]

However, in the taxonomy of Bouchet & Rocroi (2005), this subfamily was downgraded to the rank of tribe Tiberiini in the subfamily Syrnolinae.

Tiberia is the type genus of the tribe Tiberiini.

Description

The very small shells of the species in this genus have many whorls. They are umbilicate shells that lack both shell sculpture and the apertural tooth or teeth that are characteristic in most other members of the family Pyramidellidae. They may, however, have slight biplicate folds on the columella.
