Justification of Red List category
This species remained unrecorded for 50 years until it was rediscovered in 1995 near Una, Bahia, but there have been no more records from this locality despite subsequent searches. However, it has now also been found in Bandeira county, in the border of the Pardo and Jequitinhonha valleys, Minas Gerais and Bahia, where its extremely small range and population, at a single location, is declining owing to fires, logging and the clearance of steep humid valley-floor forest for cattle-ranching and agriculture. The entire population may now number just 10-15 individuals. For these reasons it is classified as Critically Endangered.

Population size: 1-49

Population trend: Decreasing

Extent of occurrence (breeding/resident): 29 km2

Country endemic: Yes

Land-mass type - continent
