Taxonomy

The family was previously in the superfamily Neritoidea in the order Neritopsina and the superorder Neritaemorphi.

2005 taxonomy

This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

• Chilodontainae Wenz, 1938
• Calliotropinae Hickman & McLean, 1990
• Cataeginae McLean & Quinn, 1987

2007 taxonomy

A molecular phylogeny-based taxonomy of the Seguenzioidea was published by Kano (2007).^[1]

It was proposed to rename the family Chilodontidae Wenz, 1938 as "Chilodontaidae" because it was a homonym of the fish family "Chilodontidae" Eigenmann, 1912, but a 2024 ICZN ruling instead changed the name of the fish family to Chilodidae, so the gastropod family is still to be kept as Chilodontidae.^[2]

The subfamilies Calliotropinae Hickman & McLean, 1990 and Cataeginae McLean & Quinn, 1987 were raised to family levels as the Calliotropidae and the Cataegidae.
