Apurimac Brush-Finch is endemic to Peru, locally fairly common in a small, isolated range in the Andes in the south of the country. It is part of a superspecies complex with two other Peruvian Endemics, Black-spectacled and Rufous-eared brush-finches, and was considered a subspecies of Rufous-eared until recently. Apurimac Brush-Finch is clean, medium gray above, with paler gray underparts. It has a bright russet crown, black lores with a white supraloral spot, and black lateral throat stripes separating a white throat and malar. It can be found very low in dense brush on arid slopes, or in the undergrowth of semi-humid woodland woodlands, from 2,700 to 4,100m. Very little is known about this species’ life history, but its habits and biology are presumably quite similar to Rufous-eared Brush-Finch.
