The Tepui Spinetail is a small ovenbird of the tepuis of southern Venezuela, western Guyana, and northern Brazil. It searches branches and bark for small prey in humid montane forest.
It is about 14–15 cm long and 14–17 g. Adults have a brown forehead, reddish-chestnut crown, wings and tail, whitish throat, and gray underparts. The sexes have the same plumage.
It inhabits evergreen montane forest and edges, mostly around 1,100–2,450 m. It gleans arthropods from bark and debris while moving along small branches; its moss nest hangs from a branch.
