Subspecies
Genus has sometimes been placed in Coerebidae or Parulidae, but molecular-genetic data indicate that it belongs in present family, with Oreomanes as sister-group. This species was originally placed in genus Ateleodacnis, and some taxonomists argue that it, along with the other lowland conebills (White-eared Conebill (Conirostrum leucogenys), Bicolored Conebill (Conirostrum bicolor) and Pearly-breasted Conebill (Conirostrum margaritae)), should be returned to that genus. As a group they are morphologically quite distinct from most highland members of present genus.
The following 3 subspecies are recognised:
guaricola Phelps & Phelps Jr, 1949 - Eastern Guárico and western Anzoátegui, in north-eastern Venezuela.
amazonum (Hellmayr, 1917) - East of Andes in western Venezuela (Apure) and eastern Colombia (south to Meta and northern Vichada); eastern Ecuador and eastern Peru; and central Guyana east to northern French Guiana, and northern Brazil (north-eastern Roraima, eastern Amazonas and west, central and north-eastern Pará).
speciosum (Temminck, 1824) - South-eastern Peru and Bolivia (except west) eastern across south-central Brazil (to Maranhío, south to Mato Grosso, Paraná and Sío Paulo), Paraguay and north-western and north-eastern Argentina (Jujuy; eastern Formosa, northern Corrientes and Misiones).
