The Bahia Antwren is distributed near the coast of Bahia and most authorities restrict the distribution to south of Salvador. However, we saw this bird north of Salvador and the distribution in this area and into the south of Sergipe is confirmed by José Fernando Pacheco (pers. comm.)

It is very similar to Black-capped Antwren H. atricapillus and Caatinga Antwren H. sellowi but it has a shorter, less graduated tail and a different voice.

There are recordings and a distribution map on xeno-canto and additional information is available through Avibase .
