The Planalto Tapaculo ("Scytalopus pachecoi") is a small passerine bird belonging to the genus "Scytalopus", a genus of tapaculos. It was previously included in the Mouse-coloured Tapaculo ("S. speluncae") but was described as a new species in 2005 based on differences in plumage and vocalizations.

It is about 12 cm long and weighs around 15 grams. The upperparts are mainly dark grey, the underparts are paler grey. The flanks are buff with dark bars. Adult males of the Mouse-coloured Tapaculo are uniformly dark grey with no flank barring.

The song contains a long series of notes uttered at a rate of two or three per second. This compares to five notes per second in the faster song of the Mouse-coloured Tapaculo. The Planalto Tapaculo has a distinctive, monosyllabic contact call and a loud alarm call.

It is known from southern Brazil (Rio Grande do Sul and Santa Catarina) and north-east Argentina (Misiones Province). It inhabits forest and forest edge where it is often found near streams and in undergrowth such as bamboo thickets. It has been found at higher densities in secondary forest rather than undisturbed forest.
