Taxonomic note
Tyto tenebricosa and T. multipunctata (del Hoyo and Collar 2014) were previously lumped as T. tenebricosa following Norman et al. (2002) and Christidis and Boles (2008), before which they had been split following Sibley and Monroe (1990, 1993) and Christidis and Boles (1994).

Closely related to T. tenebricosa, and commonly treated as conspecific, in part due to their genetic proximity (Christidis and Boles 2008, Norman et al. 2002). On basis of published information (Higgins 1999), 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 (ns1); more heavily spotted upperparts (ns1); 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 subspecies 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.

Population justification: It has been estimated to number c.2,000 breeding pairs (Higgins 1999). The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
