Justification of Red List category
This species is known only from the holotype, which was taken in 1895. There is currently minimal habitat loss at the type locality, but the lack of recent records mean any remaining population is likely to be tiny. There has not yet been sufficient targeted search effort to list the species as Extinct or Critically Endangered (Possibly Extinct), and it is therefore classified as Critically Endangered.

Population size: 1-49 mature individuals

Population trend: stable

Extent of occurrence (breeding/resident): 80 km2

Country endemic: yes
