Justification of Red List category
This poorly known species's specialised habitat is severely fragmented and is undergoing continuing rapid loss and degradation, pressures that are assumed to be causing a rapid population decline. In addition, it went unrecorded from 1932-2006, and has not been seen since despite follow-up surveys, indicating that its population is now likely to be very small. Recent estimates suggest the species's population is likely to be smaller than previously thought, and any remaining subpopulations are likely to be very small, and it has therefore been uplisted to Endangered.
