Liotiidae Explained

Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).^[1]

Description

The head of the animal is proboscidiform. The epipodial line has a pair of conical lobes and three pairs of cirri.

The white shell has a turbiniform or discoidal shape. It shows longitudinal ribs or is clathrate. The shell shows a fine lamellar sculpture. The circular aperture is feebly nacreous. The thick peristome is continuous and shows a callous varix. The multispiral operculum is hispid, corneous and has a soft, calcareous outer layer (intritacalx) formed of pearly beads that are disposed spirally.^[2]

Taxonomy

2005 taxonomy

The family Liotiidae belongs to the superfamily Turbinoidea, according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family consists of the three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

• Liotiinae Gray, 1850 - synonym: Cyclostrematidae P. Fischer, 1885; McLean (1987) ranked it as subfamily of Turbinidae.^[3]
• † Brochidiinae Yochelson, 1956
• † Dichostasiinae Yochelson, 1956

2008 taxonomy

Liotiidae was moved to the redefined superfamily Trochoidea according to Williams et al. (2008).^[4]
