Population justification: The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: Forest loss throughout this species's range has been rapid; hence, this forest specialist is suspected to be declining rapidly as well. However, the species remains very poorly known and more accurate studies are required.
