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. * † Brochidiinae Yochelson, 1956 * † Dichostasiinae Yochelson, 1956

2008 taxonomy

Liotiidae was moved to the redefined superfamily Trochoidea according to Williams et al. (2008).Williams S. T., Karube S. & Ozawa T. (September 2008) "Molecular systematics of Vetigastropoda: Trochidae, Turbinidae and Trochoidea redefined". '' Zoologica Scripta'' 37(5): 483-506.
