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

Notes:
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]
CarditamerinaeChavan, 1969
CarditesinaeChavan, 1969
MiodomeridinaeChavan, 1969
VenericardiinaeChavan, 1969
In 2019, D. E. Pérez proposed a seven-subfamily system for Carditidae. [1]
Carditamerinae
Carditinae
Miodomeridinae
PalaeocarditinaeChavan, 1969
ScalaricarditinaePérez, 2019
Venericardiinae

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]
