DEFINITIONS
HETERONETTA
(Anatidae; Ϯ Black-headed Duck H. atricapilla) Gr. ἑτερος heteros different; νηττα nētta duck; the Black-headed Duck is unique amongst wildfowl in being nest-parasitic, laying its eggs chiefly in the nests of other ducks and coots; "Il secondo genere è fondato sull' Anas melanocephala, che connette il genere Anas colle Erismature e forma il genere Etteronetta. ... Inoltre l'A. melanocephala ha un sistema di colorazione simile a quello delle Erismaturinae, ed è tale da darle una particolare fisonomia affatto diversa da quella delle vere Anas, tutte somigliantissime tra loro, e, si noti, molte tra esse poco differenti dalla femmina della specie tipica, cioè della comunissima A. boschas. Per queste ragioni stimo dover attribuire l'A. melanocephala, Vieill. ad un genere particolare. HETERONETTA, nov. gen. Characteres generis ANATIS praebet sed apice rostri valde incurvo ac strictiore; alis brevibus, SPECULO ALARI NULLO; cauda brevissima, rectricibus strictis, rigidiusculis; tarsis digitibusque mediocribus; unguibus acutis; PTILOSI ERISMATURINA. Typus ac sp. unica: Heteronetta melanocephala." (Salvadori 1865) (see Hemiparra); "Heteronetta Salvadori, Atti Soc. Ital. Sci. Nat. Milano, 8, 1865, p. [270], 374. Type, by original designation and monotypy, Anas melanocephala Vieillot (not Gmelin) = Anas atricapilla Merrem." (Peters, 1931, I, p. 172).
Var. Etteronetta (original spelling).
