Population justification: The population is estimated to number 2,500-9,999 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 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: There is no new information on population size or trend, and little is known about threats to the population. However, continuing degradation of natural habitats within the species's range, together with the rarity of field observations of the species, suggest that the population could be in slow decline.
