Poorly known, this small, yellow-green flycatcher is short-billed and long-tailed, with a pinkish lower mandible, whitish lores, and yellowish wingbars. Olive green above and yellow below. Sexes similar. Rare and nearly unknown in life; no certainty about the habitat, but presumably in forested areas. Vocalizations unknown. Similar to Sooty-headed Tyrannulet which has a black bill, lacks wingbars, and has a contrasting grayish head. Endemic to the Turimiquire region of northeastern Venezuela.
