Semeïophorus (Macrodipteryx?) vexillarius
Specific name has at times been incorrectly given as vexillaria, but vexillarius was originally described as a masculine noun in apposition to masculine genus name. Although vagrants of this species recorded in several parts of W Africa, no valid type specimen known and validity of type locality questionable; “southern Africa” suggested as a replacement#R. Present species formerly isolated in monotypic genus Semeiophorus, and subsequently placed with C. longipennis in Macrodipteryx, but recent phylogenetic study indicates that both taxa are embedded within Caprimulgus#R. Despite evident differences in morphology, the two species show similarities in vocalizations, breeding strategy, and some roosting and feeding habits, and are probably closely related. Monotypic.
