A secretive ovenbird of southeastern South American wetlands. It is closely associated with stands of Eryngium, where it nests and feeds.
Its bill is slender, straight, and about as long as the head. The back is gray-brown, the wings and tail rufous, and the eyebrow and underparts whitish to buff.
It nests and feeds in flooded wetlands with stands of Eryngium. The study describes it as secretive and strongly tied to this vegetation.
An extinction-risk assessment has not been added yet.
