The Rufous-tailed Stipplethroat lives in lowland and foothill evergreen forest in western Amazonia. Males have a gray face, whitish streaked throat, and rufous rump and tail; females are more ochre below. It gleans insects and spiders from dead leaves. Breeding biology is poorly known.
The male has a gray face, whitish throat with black streaks, olive-brown crown and back, and rufous-chestnut rump and tail. The female has an ochre throat and breast and brownish underparts. Both sexes have a red or orange iris and a dark bill.
It eats arthropods, especially insects and spiders, by gleaning dead leaves in the understory and mid-storey, including leaves caught in vine tangles. It forages alone, in pairs, or in small family groups and usually joins mixed-species flocks. Breeding details are scarce.
An extinction-risk assessment has not been added yet.
