This species was originally given the scientific name Aptenodytes antarctica by Johann Reinhold Forster in 1781, thereby placing it in the same genus as the king and emperor penguins. In 1990, Graham Turbott transferred this species into the genus Pygoscelis, together with the Adélie and gentoo penguins. This gave it the new name P. antarctica. However, this is an orthographic error due to the disagreement in Latin grammar between antarctica and its assigned genus. The corrected form, P. antarcticus, is the currently accepted name for this species.[4]
