Vigors and Horsfield, 1827,
Shoalwater Bay and Broad Sound, southern Queensland, Australia.
Sometimes separated in a monotypic genus, Stizoptera. Races intergrade in region S of Gulf of Carpentaria, from where most museum specimens are either white-rumped or black-rumped; in breeding experiments with captives, mixed pairs of black-rumped race annulosa and white-rumped nominate produced white-rumped offspring, suggesting a single genetic locus with white dominant over black. Species name was emended to “bichenoii”#R but this emendation is best considered unjustified#R. Two subspecies recognized.
