This tiny bird hides in low thickets in Java's mountains. Its very short tail, black crown, and dark eye stripe are distinctive.
It is about 7–9 cm long, with a short, rounded tail that can look almost absent. It has a black crown and eye stripe, gray eyebrow and underparts, and greenish-brown upperparts.
It occurs in Java's mountains above 1,000 m, moving actively through thickets and often hiding. Its breeding biology is little known.
