This compares to five notes per second in the faster song of the Mouse-coloured Tapaculo.

Adult males of the Mouse-coloured Tapaculo are uniformly dark grey with no flank barring.

In 2006, doubt about the use of the scientific name S. speluncae for the Mouse-coloured Tapaculo surfaced.

Until 2005, the Planalto Tapaculo was included in the Mouse-coloured Tapaculo.

A new name for the relatively well known Mouse-coloured Tapaculo, as the typically used name, Scytalopus speluncae, apparently belong to another species which previously was considered undescribed.

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.

The Mouse-coloured Tapaculo or Serra do Mar Tapaculo (Scytalopus speluncae) is a species of bird in the Rhinocryptidae family.

The name Mouse-coloured Tapaculo is likely to cause confusion, as it, until 2006, always had been used for other populations, and most, if not all, Scytalopus tapaculos are largely mouse-grey in colour.

Additionally, the relatively pale species of the central and southern Espinhaço Mountains has been called the Mouse-coloured Tapaculo (used briefly by Comitê Brasileiro de Registros Ornitológicos, but not anymore), which could add additional confusion.

Serra do Mar Tapaculo, photos and text.

The Mouse-coloured Tapaculo or Serra do Mar Tapaculo (Scytalopus speluncae) is a species of bird in the Rhinocryptidae family.

The name Serra do Mar Tapaculo for the species of the Serra do Mar region is also potentially misleading, as it is not entirely restricted to this mountain range, but also occurs far inland in Paraná and Santa Catarina.
