description of the bird as a new species. The bird's English name relates to its type locality; the scientific name to the ochraceous colour on its throat and upper breast. The species is thought to be fairly common in montane forests within its small range. Beresford, P.; Fjeldså, J. & Kiure, J.

It is a representative of the large-tailed nightjar complex found on Flores and Sumba, Indonesia. Previously unrecognised as a separate taxon due to its lack of morphological distinctness, Sangster and Rozendaal (2004) described this new species on the basis of its vocalisations, which differ significantly from those of the large-tailed nightjar races resident on other islands in the Lesser Sundas. The species is named after Gerlof Mees, former curator of the Natural History Museum, Leiden. Sangster, G. & Rozendaal, F.

The species' scientific name honours Oliverio Pinto, a Brazilian ornithologist. This species was discovered as a result of a study of museum specimens of sun parakeet and related species; specimens of this species had been dismissed as immature parakeets of other species, or hybrids.
