Taxonomie

The red-billed teal was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other ducks, geese and swans in the genus Anas and coined the binomial name Anas erythrorhyncha. Gmelin based his description on the "Crimson-billed duck" that had been described in 1785 by the English ornithologist John Latham in his A General Synopsis of Birds. Latham specied the type locality as the Cape of Good Hope. The genus name Anas is the Latin word for a duck. The specific epithet erythrorhyncha combines the Ancient Greek eruthros meaning "red" with rhunkhos meaning "bill". The species is monotypic: no subspecies are recognised.
