Chunky antshrike with a long tail and heavy bill with a hooked tip. Males are spotted black and white above (buffier in females) and brownish below with a barred tail. Found in the sub-canopy of vine tangles in humid forest, usually in pairs moving actively, but can be hard to see. The song is a long whistled trill that lasts about 5 seconds.
