Two subspecies currently recognized:
torquata, described as Caprimulgus torquatus Gmelin 1789; type locality Brazil. In some earlier literature, the name brasilianus Gmelin 1789 was widely used, rather than torquata; but the identity of brasiliana is not established, and so torquata assumes priority (Cleere 2002).
This subspecies occupies the northern part of the range of the species, south to eastern Mato Grosso and São Paulo, Brazil.
See Detailed Description.
furcifera, described as Caprimulgus furcifer Vieillot 1817; type locality Paraguay
Breeds from southeastern Peru, eastern Bolivia, and southern Mato Grosso and Paraná, Brazil south to Uruguay and Argentina; partially migratory.
Subspecies furcifera is larger than nominate torquata, and perhaps generally paler, and the nuchal collar usually is buffier (Cleere 1999).
