Taxonomic note
Megascops guatemalae and M. vermiculatus (del Hoyo and Collar 2014) were previously lumped as M. guatemalae following AOU (2003). Prior to that, M. guatemalae, plus M. atricapilla and M. hoyi (del Hoyo and Collar 2014), had been placed in the genus Otus and were treated as two species; O. atricapillus (including guatemalae and hoyi) and O. vermiculatus, following Sibley and Monroe (1990, 1993).
