(syn. Anas Ϯ African Black Duck A. sparsa) L. melas, melanos black < Gr. μελας melas, μελανος melanos black; anas, anatis duck; "It is clear that the two South African ducks commonly placed under Anas should not be retained there, the genotype (Anas platyrhyncha Linné) differing in several important respects. A. sparsa Eyton differs in having the middle toe and claw much longer than the bill, the sexes alike in colour and the colour markings very different; this species I would therefore refer to a new genus bearing the name of MELANANAS." (A. Roberts 1922) (see Afranas). Var. Melanas.
