Population justification: The single known remaining population, rediscovered in 1996 after more than 100 years, is assumed to be tiny (fewer than 50 individuals and mature individuals).
Trend justification: The species is suspected to be declining at an unknown rate, owing to ongoing forest loss within its historic range. The degree to which it can tolerate secondary growth and its ecological requirements are poorly known.
