This spinetail is largely restricted to Peru’s Apurimac Valley, where it forages in dense humid montane undergrowth and second growth; juveniles lack the adult’s rufous crown.
Adults have a dark-gray forehead and underparts, a rufous crown and folded wing, and a gray tail; the amount of black on the throat varies. Juveniles are similar but duller and lack the rufous crown.
It forages in dense undergrowth of humid montane forest, as well as in shrubs along forest edges and second growth.
