Subspecies
Relationships of genus not clearly established. Preliminary molecular evidence suggests affiliation with Thamnophilus, and morphological characteristics have connected it with Thamnomanes. Appears to form a monophyletic group with Spot-breasted Antvireo (Dysithamnus stictothorax), Plain Antvireo (Dysithamnus mentalis), Streak-crowned Antvireo (Dysithamnus striaticeps) and Spot-crowned Antvireo (Dysithamnus puncticeps) to which other species in the genus are probably closely related.
