Sayellini is a taxonomic tribe of minute ectoparasitic sea snails, marine gastropod molluscs, or micromollusks, in the very large family Pyramidellidae, the pyrams and their allies.
The subfamily Sayellinae is one of eleven recognised in the family Pyramidellidae, according to the taxonomy of Ponder & Lindberg (1997). [2]
According to Schander, Van Aartsen & Corgen (1999) there are only two genera in this sub-family. [3]
In the taxonomy of Bouchet & Rocroi (2005), this subfamily has been downgraded to the rank of tribe Sayellini in the subfamily Pyramidellinae. [4]
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs.
Odostomiinae, Odostomia snails and their allies, is a taxonomic subfamily of minute parasitic sea snails. These are marine heterobranch gastropod mollusks, or micromollusks, in the family Pyramidellidae.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Chrysallidinae is a taxonomic group of very small sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.
Cingulinini is a taxonomic tribe of very small sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Cyclostremellini is a minor tribe, a taxonomic grouping, of minute sea snails, marine gastropod mollusks or micromollusks, in the family Pyramidellidae, the pyrams and their allies.

Tiberia is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies. Tiberia is the only genus in the tribe Tiberiini.
Pyramidellinae is a taxonomic subfamily of minute sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Odostomellini is a taxonomic tribe of minute sea snails, marine gastropod molluscs within the family Pyramidellidae the pyrams and their allies.
The Aciculidae are a family of minute land snails which have opercula. In other words, Aciculidae are terrestrial operculate gastropods. Even though Aciculidae are land snails, they live in rather wet conditions, among mosses and dead leaves and they have sometimes been described as "winkles come ashore".
Pyramidelloidea is a superfamily of mostly very small sea snails, marine gastropod mollusks and micromollusks within the clade Panpulmonata.
Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.
The Helminthoglyptinae are a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks within the family Xanthonychidae.
The Ptenoglossa is an informal taxonomic group of sea snails. This group was considered paraphyletic or polyphyletic by Ponder and Lindberg (1997) in their classification of gastropod molluscs.
Euphemitidae is an extinct family of Paleozoic fossil molluscs of uncertain position. They have isostrophically coiled shells and may be either Gastropoda sea (snail)s, or Monoplacophora.
