Genera

See text for genera

The family is sometimes referred to as the freshwater pearl mussel family,[3] but "freshwater pearl mussel" more often applies to the species Margaritifera margaritifera.[4][5][6] The name refers to the thick layer of nacre (mother of pearl) lining the interior of the shell of the species, which enables them to produce pearls.

Genera

Genera within the family Margaritiferidae include:

  • Cumberlandia Ortmann, 1912
  • Gibbosula Simpson, 1900
  • Margaritifera Schumacher, 1815
  • Pseudunio Haas, 1910
  • Ptychorhynchus Simpson, 1900
  • Shepmania

Suggested redefinition

A 2018 study suggested a new phylogeny and systematics of the Margaritiferidae, comprising two subfamilies, Gibbosulinae and Margaritiferinae, and four genera, Gibbosula, Cumberlandia, Margaritifera, and Pseudunio.[7]
