Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda. [1]
The Calliostomatidae are unusually diverse. They are characterized by a stepped spire and a pointy aperture. They may possess or lack an umbilicus. The collumella is sometimes thicker, partially covering the aperture. The spiral whorls can differ between narrow and robust. They inhabit a wide range of ocean habitats, from the intertidal zone to mid-bathyal depths.
This taxon was long considered to be a subfamily of the Trochidae.
This family consists of two following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): [2]
According to Williams et al. (2008) [3] the Calliostomatidae stays in Trochoidea. Up to 2008 there were only two species Calliostoma javanicum and Calliostoma unicum that were used in molecular phylogeny studies. [3]
The first molecular phylogeny study of the family Calliostomatidae was made by Williams et al. (2010) [4] Based on molecular data, they confirmed that Thysanodontinae Marshall, 1988 belongs to the family Calliostomatidae,. [4] It was already previously placed there based on morphological data. [4]
The tribe Fautricini B. A. Marshall, 1995 was raised to the rank of subfamily Fautricinae B. A. Marshall, 1995 [5]
Genera included in this family: [6]
Conidae, with the current common name of "cone snails," is a taxonomic family of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea.

Previously this genus was placed within the family Trochidae. Calliostoma is the type genus of the family Calliostomatidae.
