Carditidae is a family of marine bivalve clams of the order Carditida, which was long included in the Venerida. They are the type taxon of the superfamily Carditoidea.

Carditidae is a neglected and poorly classified family.[1][2] It has six subfamilies recognised by the World Register of Marine Species, but the WoRMS has refrained from assigning contents to any family due to ambiguity and overlap in their definitions.[3][2] Additionally, several genera have been or are still considered subgenera of other genera by some authors.

Genera[edit]

The genera of Carditidae recognised by the World Register of Marine Species as of April 2019 are:

Synonyms:

  • Arcturella Chavan, 1941 is a junior synonym of Arcturellina. It is not to be confused with Arcturella Sars, 1879, which is a junior synonym of the isopod genus Astacilla.
  • Azarella is a junior synonym of Beguina.
  • Agaria, Cardiocardites [sic] and Divergidens are junior synonyms of Cardiocardita.
  • Actinobolus Mörch, 1853 is a junior synonym of Cardites. It is not to be confused with the rhinoceros beetle genus Actinobolus Westwood, 1842.
  • Ceropsis Dall, 1871 is a junior synonym of Milneria. It should not be confused with the true weevil genus Ceropsis.
  • Miodon Carpenter, 1863 is a junior synonym of Miodontiscus. It should not be confused with Miodon Duméril, 1859, which is a junior synonym of the mole viper genus Polemon.

Notes:

  • In some classifications, Bathycardita is a subgenus of Cardiocardita.[4]
  • In some classifications, Centrocardita is a subgenus of Glans.[5]
  • In some classifications, Claibornicardia is a subgenus of either Glyptoactis or Venericardia.[6]
  • In some classifications, Vimentum is a subgenus of Cyclocardia.[7]
  • In some classifications prior to the 2000s, Carditella was included in Carditidae,[8] but it has since been moved to Condylocardiidae,[9] along with its former junior synonym/subgenus (now independent genus) Carditellona.[10]
  • Increasingly in several 2010s classifications, the subgenus Venericardia (†Baluchicardia) Rutsch and Schenck 1943[11] is considered an independent genus.[1][12][13]

Subfamilies[edit]

Chavan, 1969[edit]

The original six-subfamily system was first proposed by Chavan in 1969, contain the following genera (some of which are now synonyms or classified in other families):[1]

Carditamerinae Chavan, 1969

Carditesinae Chavan, 1969

Carditinae Férussac, 1822

Miodomeridinae Chavan, 1969

Thecaliinae Dall, 1903

Venericardiinae Chavan, 1969

Perez, 2019[edit]

In 2019, D. E. Pérez proposed a seven-subfamily system for Carditidae.[1]

Carditamerinae

Carditinae

Miodomeridinae

Palaeocarditinae Chavan, 1969

Scalaricarditinae Pérez, 2019

Thecaliinae

Venericardiinae

* = not yet recognised by the World Register of Marine Species.

In addition, Pérez proposed possible affiliations for the genera not included in his subfamilies:[1]

In some classifications prior to the 2000s, Carditidae used to contain a seventh subfamily Carditellinae, until it was reallocated to Condylocardiidae.[8]
