Chilodontaidae Explained

Chilodontaidae is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

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]

The family Chilodontidae Wenz, 1938 will be renamed because it is a homonym of the fish family Chilodontidae Eigenmann, 1912; (to be emended to Chilodontaidae by ICZN^[2])

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