Quoy and Gaimard, 1830,
King George Sound, south-west Australia.
Sister to M. cyaneus; see that species. Races originally treated as constituting three separate species, but interbreed wherever they meet. Race callainus previously listed under junior synonym musgravi, as name callainus was claimed to be invalid because type specimen was thought to be an intergrade#R; this procedure has been refuted#R#R, and in any case subsequent review of the type has revealed that intergradient traits are negligible#R. As many as seven races described from early collections, but later studies have shown that most represent clinal variation, e.g. whitei (interior New South Wales) regarded as representing part of clinal variation of melanotus, and aridus (interior of Western Australia) now included in nominate. Four subspecies recognized.
