Boie, 1822 | subdivision_ranks = Species | subdivision = 12 species, see text }}Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, aithuia, which may have referred to a sea-dwelling duck or an auklet.[1] Aythya shihuibas was described from the Late Miocene of China. Zelenkov (2016) transferred the species Anas denesi Kessler (2013), known from the late Miocene of Hungary, to the genus Aythya.[2] An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey;[3] it might however be referrable to a paleosubspecies of an extant species considering its age (see also Greater scaup). The Miocene{{Verify source|date=February 2008}} "Aythya" arvernensis is now placed in Mionetta, while "Aythya" chauvirae seems to contain the remains of two species, at least one of which does not seem to be a diving duck.[4] Aythya species
