Close
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.
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]
