Previously considered closely related to, or even conspecific with, Hydropsalis cayennensis (both taxa were at the time placed in Caprimulgus). Later review, however, suggested that the two were not close and that present species probably belonged with Eleothreptus#R; a treatment strongly supported by subsequent phylogenetic study#R. Monotypic.

Distribution:

N Bolivia (Beni Biological Station, in Beni)#R, SC Brazil (Emas National Park, in SW Goiás)#R, and E Paraguay (Mbaracayú Forest Nature Reserve, in Canindeyú; Laguna Blanca, in San Pedro)#R#R. Historical records from Mato Grosso and São Paulo, in S Brazil.
