Taxonomy: Trochilus longirostris Audebert and Vieillot, 1801, Trinidad.
Present species and H. constantii occasionally separated in genus Anthoscenus, on basis of squarish tail, rounded rectrices and details of bill morphology; however, the distinguishing features vary in a continuum between these species and H. furcifer, with H. squamosus occupying an intermediate position, and treatment of all four as congeners now generally considered more appropriate; some authors also merge Rhodopis.

Taxonomy: Trochilus longirostris Audebert and Vieillot, 1801, Trinidad.
Present species and H. constantii occasionally separated in genus Anthoscenus, on basis of squarish tail, rounded rectrices and details of bill morphology; however, the distinguishing features vary in a continuum between these species and H. furcifer, with H. squamosus occupying an intermediate position, and treatment of all four as congeners now generally considered more appropriate; some authors also merge Rhodopis. Several additional races described, notably masculinus (SC Mexico), veraguensis (Panama), chalcurus (Costa Rica), stuartae (Colombia) and caeruleiceps (Bolivia), but most have not been sustained and now included within nominate; separation of pallidiceps from nominate has been questioned. Three subspecies currently recognized.

Subspecies and Distribution:

  • pallidiceps Gould, 1861 - S Mexico to Nicaragua.
  • longirostris (Audebert & Vieillot, 1801) - E & SW Costa Rica, Panama and Colombia S to E Bolivia and C & NE Brazil; Trinidad.
  • albicrissa Gould, 1871 - W Ecuador and NW Peru.
