Mareca is a genus or subgenus of ducks in the family Anatidae that includes the wigeons.
The species now placed in this genus were formerly placed in the genus Anas. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus Anas, as then defined, was not monophyletic.[1] Based on the published phylogeny, the genus Anas was split into four monophyletic genera with five extant species moved into the resurrected genus Mareca.[2]
The genus Mareca was introduced by English naturalist James Francis Stephens in 1824. The type species is the Eurasian wigeon.[3][4] The name of the genus is from the Portuguese word Marreco for a small duck.[5]
