Summary: | Percnostola rufifrons jensoni, a new subspecies of Black-headed Antbird, is described from northeastern Peru on the north bank of the Amazon River east of its confluence with the Napo River. Comparison with the three other subspecies and the historical taxonomic treatment of formicariids suggests this complex consists of two pairs of subspecies that should be ranked as species, Percnostola rufifrons rufifrons + Percnostola rufifrons subcristata (= Percnostola rufifrons, the Black-headed Antbird, with two subspecies rufifrons and subcristata) and Percnostola rufifrons minor + Percnostola rufifrons jensoni (= Percnostola minor, the Amazonas Antbird, with two subspecies minor and jensoni). /// Percnostola rufifrons jensoni, una nueva subespecie de Hormiguero Cabecinegro, ha sido descrita desde el noreste del Perú sobre el banco norte del Río Amazonas al este de su confluencia con el Río Napo. Comparaciones hechas con las otras tres subespecies, además del tratamiento histórico del grupo de los formicáridos, sugieren que este complejo consiste de dos pares de subespecies que deben ser jerárquizados como especies, Pernostola rufifrons rufifrons + Percnostola rufifrons subcristata (= Percnostola rufifrons, el Hormiguero Cabecinegro, con dos subespecies rufifrons y subcristata) y Percnostola rufifrons minor + Percnostola rufifrons jensoni (= Percnostola minor, el Hormiguero Amazonas, con dos subespecies minor y jensoni). |
