Taxonomy

Nacellidae was the only family in the superfamily Nacelloidea as described by Bouchet & Rocroi (2005),.^[2] However a molecular phylogenetic study of Patellogastropoda by Nakano & Ozawa (2007) found that Nacellidae was recovered within Lottioidea, as shown in the following cladogram:^[4]

Patellogastropoda	Lottiidae (including Acmaea and Niveotectura) Pectinodontidae Lepetidae Nacellidae Patellidae Eoacmaeidae

As a result Nacellidae was moved to Lottioidea in the taxonomic revision of Bouchet et al (2017).^[3] More recently, a recent phylogenomic study found Nacellidae as a sister to Patellidae, which suggests that Nacellidae should be transferred to Patelloidea.^[5][6]

Genera

Genera within the family Nacellidae include:^[6]

• Cellana H. Adams, 1869
• Naccula Iredale, 1924^[7]
• Nacella Schumacher, 1817 - type genus
• Macclintockia Gould, 1846: taxon inquirendum
  • - one species Macclintockia scabra (Gould, 1846): synonym of Lottia scabra (Gould, 1846)
