A small tyrannulet of Brazil's Atlantic Forest. It uses the canopy and subcanopy and occurs in mixed-species flocks.
It is reported at about 12 cm long and 8 g. Adults have a wide yellow eye-ring and a dark line through the eye that continues around the ear-coverts.
In December 2007, one nest 2.3 m high at a secondary-forest edge was observed; adults brought insects and spiders.
An extinction-risk assessment has not been added yet.
