See text Pectinodontidae is a family of sea snails or true limpets, marine gastropod mollusks in the superfamily Lottioidea, the true limpets.
[1] This family was previously ranked as subfamily Pectinodontinae (also with Acmaeinae and Rhodopetalinae) in the family Acmeaidae in the taxonomy of the Gastropoda by Bouchet & Rocroi (2005).
Nakano & Ozawa (2007)[2] elevated Pectinodontinae to family level Pectinodontidae based on molecular phylogeny research.
