Nacellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the subclass Patellogastropoda.
Taxonomy
Nacellidae was the only family in the superfamily Nacelloidea as described by Bouchet & Rocroi (2005),. However a molecular phylogenetic study of Patellogastropoda by Nakano & Ozawa (2007) found that Nacellidae was recovered within Lottioidea, as shown in the following cladogram:
| Patellogastropoda | Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae Patellidae Eoacmaeidae |
| Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae Patellidae | |
| Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae | |
| Lottiidae (including Acmaea and Niveotectura) | |
| Pectinodontidae Lepetidae Nacellidae | |
| Pectinodontidae Lepetidae | |
| Pectinodontidae | |
| Lepetidae | |
| Nacellidae | |
| Patellidae | |
| Eoacmaeidae | |
As a result Nacellidae was moved to Lottioidea in the taxonomic revision of Bouchet et al (2017). More recently, a recent phylogenomic study found Nacellidae as a sister to Patellidae, which suggests that Nacellidae should be transferred to Patelloidea.
