Pyramidellinae is a taxonomic subfamily of minute sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies. [2]
It is one of eleven recognised subfamilies of the marine gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997), which are as follows: Odostomiinae, Turbonillinae, Chrysallidinae, Cingulininae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae.
In the taxonomy of Bouchet & Rocroi (2005), [3] this subfamily consists of the following tribes, adding the tribe Sayellini containing only two genera Sayella and Petitella .
According to Schander, Van Aartsen & Corgen (1999) [4] there are 12 genera within the Pyramidellinae:
tribe Pyramidellini
tribe Sayellini
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.
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.
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.
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.
Eulimellini is a tribe of minute sea snails, marine gastropod molluscs 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.
The Trochidae, common name top-snails or top-shells, are a taxonomic family of very small to large sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.
Odetta is a genus of small sea snails, marine gastropod molluscs in the subfamily Odostomiinae, which is a voluminous taxon of minute marine gastropods with a heterostrophic protoconch.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Pendromidae is a family of gastropods in the clade Vetigastropoda.
Solariellidae is a family of small sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Cylichnidae, common name the "chalice bubble snails" or "canoe bubble snails" is a family of sea snails or bubble snails, marine gastropod mollusks in the superfamily Cylichnoidea.
Bittium is a genus of very small sea snails, marine gastropod molluscs in the family Cerithiidae, the horn snails.
Murchisonellidae is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Murchisonelloidea.
Pyramidella is a genus of minute to medium-sized sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.
Longchaeus is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Triptychus is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
