Taxonomy

The sooty barbthroat was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Trochilus niger. [2] The type locality is Cayenne in French Guiana.[3] The sooty barbthroat is now placed in the genus Threnetes that was introduced by John Gould in 1852.[4][5]

Two subspecies are recognised:[5]

  • T. n. niger (Linnaeus, 1758) – French Guiana and northeast Brazil
  • T. n. loehkeni Grantsau, 1969 – northeast Brazil (north of the Amazon)

The taxonomy and systematics of the sooty/pale-tailed barbthroat complex has caused much confusion. Some authors[6] consider the sooty barbthroat to be a melanistic variant of the pale-tailed barbthroat (T. leucurus). As T. niger was described first, this scientific name is the valid name for both when they are considered conspecific.

On the other hand, the SACC for example considers T. niger and T. leucurus distinct species, because of insufficient published evidence for their being conspecific.[7] This "combined" species is considered to be of Least Concern by the IUCN.[1][8]

In addition, some suggest that the bronze-tailed barbthroat (T. n. loehkeni) should also be considered a valid species and include the doubtful Christina's barbthroat (T. n. christinae) as a subspecies. Freire's sooty barbthroat (T. n. freirei) is intermediate between the sooty and bronze-tailed barbthroats however, and thus its status needs to be clarified before the situation is resolved.[9]
