Subspecies
Genus formerly considered monotypic, with Standard-winged Nightjar (Caprimulgus longipennis) separated from present species in genus Semeiophorus. However, despite the evident differences in morphology, the two species show notable similarities in vocalizations, breeding strategy, and some roosting and feeding habits, as well as a number of morphological affinities, and so are probably best considered congeneric. Specific name has at times been incorrectly given as vexillaria, but vexillarius originally described as masculine noun in apposition to masculine genus name. Validity of type locality is questionable, although vagrants have been recorded in several parts of western Africa.
