Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.MolluscaBase (2018). Turbonillinae Bronn, 1849.

This subfamily has been shown to be monophyletic Angela Dinapoli, Carmen Zinssmeister and Annette Klussmann-Kolb (2010), New insights into the phylogeny of the Pyramidellidae (Gastropoda), Journal of Molluscan Studies Volume 77, Issue 1 Pp. 1-7

Taxonomy In the taxonomy of Schander, Van Aartsen & Corgan (1999) Turbonillinae is a part of the family Turbonillidae. Family Turbonillidae Bronn, 1849 Subfamily Turbonillinae Bronn, 1849 Subfamily Cingulininae Saurin, 1958 Subfamily Eulimellinae Saurin, 1958

According to Schander, Van Aartsen & Corgan (1999) there are 27 genera within the Turbonillinae.

Turbonillinae has been one of eleven recognised subfamilies in the family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997).

In the taxonomy of Bouchet & Rocroi (2005), this subfamily comprises the subfamilies Cingulininae and Eulimellinae, that have been downgraded to the rank of tribe. Subfamily Turbonillinae Bronn, 1849 Tribe Turbonillini Bronn, 1849 Tribe Cingulinini Saurin, 1958 Tribe Eulimellini Saurin, 1958

In 2010 the subfamily Turbonillinae has been recognized as monophyletic

The genus Ebala was previously placed in the Eulimellinae, but was then placed in the family Ebalidae, that is a synonym of Murchisonellidae.

Distribution This family is found worldwide.

Shell description The shell of these snails has a blunt, heterostrophic protoconch, which is pointed sideways. The shell of most species are rather high and slender.

The texture of these shells is usually ribbed sculptured in various forms and often also have more or less prominent spirals. Their color is mostly white, cream or yellowish, sometimes with red or brown lines.

The adult shell, the teleoconch is dextrally coiled, but the larval shells are sinistral. This results in a sinistrally coiled protoconch. The opening of the shell, the aperture is closed by a lid, a so called operculum.

Life habits The Turbonillinae are ectoparasites, feeding mainly on other molluscs and on annelid worms.

They do not have a radula. Instead their long proboscis is used to pierce the skin of its prey and suck up its fluids and soft tissues. The eyes on the grooved tentacles are situated toward the base of the tentacles. Between the head and the foot, a lobed process called the mentum (= thin projection) is visible.

These molluscs are hermaphrodites.
