Apparently closest to C. nigrolineata; sometimes treated as conspecific with latter, but differs in size, voice and plumage. An owl discovered in N Ecuador (W Napo) recently identified as of present species, but voice somewhat different (more like that of C. nigrolineata#R); may be an undescribed race or even a new species (“San Isidro Owl”); further studies, including larger DNA samples for analysis, needed. Two subspecies currently recognized.
