The term "caatinga antwren" refers to a specific species of bird scientifically known as Herpsilochmus sellowi. It is a small and insectivorous passerine bird belonging to the antbird family Thamnophilidae.
The caatinga antwren is endemic to the caatinga biome in northeastern Brazil, which is characterized by dry and semi-arid conditions. It has a distinct appearance, with males typically exhibiting dark olive-brown plumage on their upperparts and a black crown, while females have a lighter brown coloration.
