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 columella 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

For a long time, this taxon was 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]

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]
