Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.^[1]

Description

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.

Taxonomy

This taxon was long considered to be a subfamily of the Trochidae.

2005 taxonomy

This family consists of two following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):^[2]

subfamily Calliostomatinae Thiele 1924 (1847)
- tribe Calliostomatini Thiele 1924 (1847) - synonym: Ziziphininae Gray, 1847
- tribe Fautricini Marshall, 1995
subfamily Thysanodontinae Marshall, 1988

2008 taxonomy

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]

2010 taxonomy

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]

2016 taxonomy

The tribe Fautricini B. A. Marshall, 1995 was raised to the rank of subfamily Fautricinae B. A. Marshall, 1995 ^[5]
