The mouse-coloured tapaculo or Serra do Mar tapaculo (Scytalopus speluncae) is a species of bird in the family Rhinocryptidae. It is endemic to humid highland forests in southeastern Brazil, where it ranges from southwestern Espírito Santo to northeastern Rio Grande do Sul. Most of its range is in the Serra do Mar, but it also occurs further inland in Paraná and Santa Catarina. Until 2005, the Planalto tapaculo was included in the mouse-coloured tapaculo. Here we follow SACC, but the taxonomy is extremely complex, and it is possible the correct scientific name of this relatively dark species is S. notorius, in which case the closely related paler species from the Espinhaço Mountains region would be S. speluncae. == Taxonomy == In 2005, it was found that the otherwise relatively well known S. speluncae actually consisted of two species, of which the southern was described as a new species, S. pachecoi, while the northern retained S. speluncae. It was further suggested that S. speluncae included yet another undescribed species, but more work was needed on that matter. === Scientific name === In 2006, doubt about the use of the scientific name S. speluncae for the mouse-coloured tapaculo surfaced.
