Placed in genus Antrostomus by some authors#R. Previously considered closely related to, or even conspecific with, Eleothreptus candicans (both taxa were at the time placed in Caprimulgus); later studies, however, have indicated that the two are not close#R#R. Race leopetes sometimes treated as a synonym of nominate#R. Six subspecies recognized.
