Formerly considered conspecific with the rather more widespread Chestnut-backed Antshrike (Thamnophilus palliatus), the Lined Antshrike is confined to the east slope of the northern Andes, between north-central Colombia and northeast Peru, and inhabits the edge of humid forest and scrub at elevations ranging from 200 to 2500 m. The plumage of females of these two species is basically very similar, but the male Lined Antshrike differs substantially from the same sex of Chestnut-backed Antshrike in having a black, barred white, back, wings, and tail, whereas these parts are entirely rufous in its apparent sister-species. Usually reasonably common, the Lined Antshrike is normally found alone or in pairs, and does not routinely join mixed-species foraging flocks.
