The grey wren is 11.5 cm long. The adults have a lead-gray crown and upperparts; the tail is also gray with broad blackish bars. It has a faint whitish supercilium and the rest of the face is gray. The throat is whitish gray, the chest gray, and the belly a slightly buffy gray.

The grey wren is known only from a small area of Brazil, along the right bank of the Rio Javarí and the upper reaches of the Rio Juruá and Rio Purus to the southeast. The Rio Javari forms the border with Peru but the species is unknown on that side of the river. It is a bird of thick vegetation, inhabiting overgrown clearings and the undergrowth of "várzea" forest. In elevation it ranges only as high as 200 m.Status
