Identificación

The plumbeous antvireo is about 12 to 13 cm (4.7 to 5.1 in) long. Adult males have a dark gray head, upperparts, and tail with a hidden white patch between the scapulars. Their wings are black with white tips and edges on the coverts. Their underparts are a darker blackish gray than the upperparts. Adult females have an olive-brown head and upperparts with buff-white spots on the wing coverts. Their throat is very pale gray, their breast olive-brown, and their belly and crissum ochraceous.

Taxonomía

The plumbeous antvireo was originally described in genus Myiothera, which is no longer in use. It was eventually transferred to Dysithamnus but around 1970 was moved by at least one author to genus Thamnomanes. This treatment was not widely accepted and by the 1980s it was confirmed to belong in Dysithamnus.<p>The plumbeous antvireo and what is now the white-streaked antvireo (D. leucostictus) were for a time treated as conspecific; they were separated in the early 2000s. The plumbeous antvireo is monotypic.

Distribución y hábitat

The plumbeous antvireo is found locally in southeastern Brazil in an area roughly bounded by southern Bahia, eastern Minas Gerais, Espírito Santo, and northern Rio de Janeiro states. It is a bird of the Atlantic Forest, where it inhabits the understory of evergreen forest. It occurs almost exclusively in primary or slightly disturbed forest and favors overgrown openings such as those created by fallen trees. In elevation it mostly occurs below 600 m (2,000 ft) but is found as high as 900 m (3,000 ft).
