The band-tailed antwren is a bird of the Atlantic Forest. It found very spottily and locally in coastal eastern Brazil between Bahia and northern Rio de Janeiro state. The largest numbers are found in the southern Bahia-northern Espírito Santo area. It inhabits the understorey to mid-storey of evergreen forest and adjacent mature secondary forest in the lowlands. It appears to favor tall forest on sandy soil, especially those with abundant vines in their lower reaches. In elevation it occurs below about 500 m (1,600 ft).
