This small antwren is recorded in humid forest in northeastern Brazil. Males are gray and females are rufous-brown; a 2005 survey documented one male in a forested valley with a stream and dense lianas.
The male is gray overall with an indistinct black throat patch. The female is fulvous-brown above with a russet tail, rufous-buff underparts, and a white throat.
A 2005 survey recorded one adult male at Mata do Benedito in Pernambuco, in a narrow valley forest with a small stream and dense liana understory. The paper's review of records describes the species in wet, often misty upland forest, commonly near small creeks.
