Johnstone River, north Queensland, Australia

Closely related to T. tenebricosa, and commonly treated as conspecific, in part due to their genetic proximity#R#R. On basis of published information#R, however, present species differs in much smaller size (effect size for female wing −10.4; score 4); longest primary P7, not P8 (1); slightly greyer plumage (ns[1]); more heavily spotted upperparts (ns[1]); white breast with dark markings vs dark with white (2); vermiculations of wings and tail much heavier and arranged in distinct cross-bands (1); more extensively white bases of flight-feathers and secondary coverts, forming larger pale centre of underwing (1); sexual size dimorphism weaker (ns); different calls (although probably a function of smaller size) (1). Thus, here recognized as a separate species, although occurring between the ranges of the two races of T. tenebricosa; these two species have occasionally been separated in genus Megastrix. As recently as 1940, present species was considered not to differ even subspecifically from T. t. tenebricosa. Monotypic.
