Gr. νησιωτης nēsiōtēs  islander  < νησος nēsos  island.
● The Campbell Island Teal is confined to one small island of the Campbell Is. group south of New Zealand. Marchant & Higgins 1990, assumed the name to be a compound of Gr. νησιον nēsion islet, and ωτις ōtis eared (i.e. the island form of Anas chlorotis). No etymology is given in the original description (J. Fleming 1935), and the name could also be construed a compound of the specific combinations Nesonetta aucklandica, Auckland Island Teal, and Elasmonetta chlorotis, Brown Teal, with which species A. nesiotis was directly compared (Anas).
● “The name ‘Island-hen’ given to this bird by the inhabitants of Tristan d’Acunha has suggested to me the specific name nesiotis” (P. Sclater 1861) (Gallinula).
