See S. humilis; see also S. keri, which has probably hybridized with race laevigaster. Otherwise, races of present species form three broad groups, E “frontalis group”, W “maculatus group”, and monotypic NE “laevigaster group”; plumage and vocal differences suggest that these could perhaps be treated as three distinct species, but laevigaster intergrades with tweedi over a 100-km zone in S Queensland and N New South Wales, and in South Australia mellori probaby intergraded with rosinae around Gulf St Vincent prior to foundation of metropolitan Adelaide (intergrades from this area described as taxon osculans). Other proposed races include herbertoni (NE Queensland), a synonym of laevigaster; longirostris (coastal SE South Australia), included in nominate; in Bass Strait, gularis (Kent Group) and insularis (nearby Forsyth I), apparently intermediates between nominate and flindersi and merged with latter; and mondraini (Recherche Is, in S Western Australia), merged with mellori. Ten subspecies currently recognized.
