Population justification: The population is estimated to number 250-999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 167-666 mature individuals, rounded here to 150-700 mature individuals.
Trend justification: Forest degradation is ongoing in the region, thus the species's population is suspected to be declining slowly.
