A strongly marked wren recorded from Venezuelan savanna and woodland. At one central Venezuelan study site, group members helped breed and defend nests.
It is dull white overall, with dark streaking above, black dots below, a broad white eyebrow, and black-and-white barred wings and tail. The eyes are yellowish white.
At Hato Masaguaral, groups contained 2–10 birds; 59 groups in 1991 averaged about four. Groups held year-round territories, and helpers joined the dominant pair in breeding and nest defense. Breeding followed the first heavy rains, with nests 2–10 m above ground in trees or palms.
