Sometimes placed in monotypic genus Macabra, or that name used as subgenus, on basis of lack of erectile ear tufts; vocal patterns, however, show close relationship with Megascops. Recent study using single mitochondrial gene suggested close relationship to largely Middle American M. trichopsis#R; this supported by subsequent study using three nuclear and three mitochondrial genes, which placed present species in clade with M. trichopsis, M. choliba, M. koepckeae and M. clarkii#R. Race obscurus possibly only a morph, or result of individual variation, and sometimes included in meridensis or remotus#R. E Ecuador form aequatorialis, treated as synonym of M. ingens, has previously been considered a race of present species or synonymized with nominate albogularis. Five subspecies recognized.
