Odostomellinae
Odostomellini is a taxonomic tribe of minute sea snails, marine gastropod molluscs within the family Pyramidellidae the pyrams and their allies.
Odostomellinae has been one of eleven recognised subfamilies of the family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997). The subfamily contains two genera: Herviera and Odostomella (Schander and co-workers 1999).
In the taxonomy of Bouchet & Rocroi (2005), this subfamily has been downgraded to the rank of tribe Odostomellini in the subfamily Odostomiinae.
Genera within the tribe Odostomellini include:
The subfamily occurs in tropic and temperate seas.
The shell of these snails has a blunt, heterostrophic , which is wrapped up. The texture of these shells is sculptured with ribs. Their color is mostly white, brown, cream or yellowish, sometimes with red or brown lines. The teleoconch is coiled, but the larval shells are . This results in a sinistrally coiled protoconch. The aperture is closed by an operculum.
The Odostomellinae are ectoparasites, but the hosts are unknown.
