Nyctipolus nigrescens is monotypic, although populations in Colombia and Ecuador are possibly browner (paler) compared to birds from the Guianas and Peru (Cleere 1998).

Related Species

Described as Caprimulgus nigrescens Cabanis 1848 (in Schomburgk 1848); type locality Lower Essequibo River, Guyana

For many years nigrescens was classified in the genus Caprimulgus, a genus that eventually encompassed a large number of species of nightjars worldwide (Peters 1940, Dickinson 2003). Phylogenetic analysis of DNA sequence data, from both mitochondrial and nuclear genes, reveals that the broadly defined Caprimulgus of Peters (1940) and other authors is highly polyphyletic (Han et al. 2010, Sigurdsson and Cracraft 2014). Caprimulgus proper is entirely confined to the Old World, and New World species of "Caprimulgus" are split into several clades (Han et al. 2010, Sigurdsson and Cracraft 2014). "Caprimulgus" nigrescens is sister to "Caprimulgus" hirundinaceus (Pygmy Nightjar) (Sigurdsson and Cracraft 2014), and both species now are classified in the genus Nyctipolis.
