Podilymbus

Podilymbus is a genus of birds in the Podicipedidae family, containing the extinct Atitlán Grebe (Podilymbus gigas) and the Pied-billed Grebe (Podilymbus podiceps). There are also several prehistoric taxa of Podilymbus described from fossil remains:

 * Podilymbus wetmorei (Late Pleistocene of Florida)
 * Podilymbus podiceps magnus - a paleosubspecies of the Pied-billed Grebe of uncertain validity.
