St[rix]? Novæ Hollandiæ
New South Wales, Australia.
Closely related to T. aurantia, T. almae, T. nigrobrunnea and T. inexspectata. In recent decades, race castanops sometimes treated as a separate species#R#R#R, and recent molecular analysis suggests that this is appropriate#R; further evidence (e.g. morphological, vocal and genetic) is needed, however. Meanwhile, size and colour variation within S Australian populations support inclusion within present species, at subspecific level. In addition, forms sororcula and manusi, previously treated as two separate species, recently found to be better treated as races of present species#R; further, has been suggested that New Guinea population calabyi is approaching species level, but again differences seem not to be sufficiently marked, and this taxon recently found#R to be more closely related to cayelii, which was previously treated as a race of sororcula when latter given full species status. Race galei sometimes merged with kimberli, as observed differences may not be constant and few specimens have been used in analyses. Birds of SW Western Australia may merit separation as a distinct race owing to significantly larger size, but more study needed; formerly separated in race perplexa. Cave-dwelling population of South Australia described as troughtoni; may be worthy of subspecific treatment, but remains very poorly known. Nine subspecies currently recognized.
Introduced (castanops) to Lord Howe I.
