Justification:
Recorded from two unprotected areas on limestone ridges with very small populations, each with fewer than 100 individuals. The distribution range is poorly known and is expected to be larger. The assessment is based on a 50% reduction in the habitat quality due to the impacts of deforestation.

History:

1998	–	Data Deficient (Oldfield et al. 1998)

Systems:	Terrestrial
