Justification of Red List category
After its discovery in 1955, the species has not been recorded until six individuals were found in 2016. Although it persists within a large national park, it probably has a tiny population which is likely to be declining owing to ongoing forest loss in the region (Collar et al. 1992). For these reasons it qualifies as Critically Endangered.

Population size: 1-49

Population trend: Decreasing

Extent of occurrence (breeding/resident): 500 km2

Country endemic: Yes

Land-mass type - continent
Realm - Neotropical
IUCN Ecosystem -- Terrestrial biome
