Subspecies
Some authors include Cranioleuca in present genus because of general morphological similarities, but most treat them as separate genera because of differences in nest structure. Birds from north-eastern Colombia (northern Arauca) assumed to belong to subspecies marabinus, and those from western part of R Amazon (east to R Negro) tentatively placed with pallidus. Further study is needed.
Proposed subspecies albescentior, described from Carabobo, in northern Venezuela, is a synonym of valencianus.
The following 8 subspecies are recognised:
fuscifrons (Madarász, 1913) - Northern Colombia (R Atrato east to base of Santa Marta Mts, also lower Cauca Valley and most of Magdalena Valley).
marabinus Phelps & Phelps Jr, 1946 - North-western Venezuela (Zulia west of L Maracaibo, and western Trujillo, western Mérida and north-western Táchira) and north-eastern Colombia (northern Arauca).
valencianus Zimmer, JT & Phelps, 1944 - West-central Venezuela (Lara, Portuguesa and Barinas east to Aragua and Guárico).
orenocensis Zimmer, JT, 1935 - Lower Orinoco Valley in Venezuela (southern Apure, south-eastern Guárico, northern Amazonas, and northern Bolívar east to southern Sucre and Delta Amacuro).
cinnamomeus (Gmelin, 1788) - Trinidad, north-eastern Venezuela (northern Sucre, northern Anzoátegui), the Guianas and north-eastern Brazil (Pará east to northern Maranhío).
pallidus Zimmer, JT, 1935 - Extreme south-eastern Colombia (south-eastern Amazonas) and western and central Amazonian Brazil (E, including lower R Negro and lower R Purús, to lower R Tocantins).
russeolus (Vieillot, 1817) - Eastern Bolivia (southern from Pando), southern Brazil (central Mato Grosso east to southern Bahia, and south to Rio Grande do Sul), Paraguay, northern Argentina (south to Salta, north-eastern Córdoba and northern Buenos Aires) and Uruguay.
