Population justification: No population estimates are available for this poorly known species, but it is regularly seen and known from multiple locations. It is tentatively placed in the band of 10,000-19,999 mature individuals (equating roughly to 15,000-30,000 individuals in total). However, the true population size might be much lower.

Trend justification: The population is most likely patchily distributed and suspected to be in decline owing to ongoing habitat destruction and fragmentation.
