Taxonomy and systematics

Description
The white-browed tapaculo is {{convert|10.5|cm|in|abbr=on}} long. The nominate adult's most striking features are its long white supercilium, throat, and upper breast. The back and wings are grayish brown to brownish gray. The lower breast is gray. The rump is brown with fine bars. The flanks, belly, and crissum (the area around the cloaca) are pale olive-brown with black bars. Subspecies S. s. santabarbarae is darker, with upper parts trending to chestnut and the underparts being blackish-brown instead of gray.
Distribution and habitat
The white-browed tapaculo is found only in northwestern Argentina. The nominate subspecies ranges from Jujuy Province south to northern La Rioja Province. Subspecies S. s. santabarbarae is probably limited to the Santa Bárbara Mountains of Jujuy, though it might also extend into Salta Province.
The white-browed tapaculo inhabits the undergrowth of Alnus and Polylepis woodlands, often in shaded rocky ravines. In elevation it ranges from {{convert|1500|to|3350|m|ft|abbr=on}}.
