Population justification: The species’s population is estimated to number 50-249 mature individuals, based on a known population of c.14 individuals. This is assumed to be equivalent to c.70-380 individuals in total.

Trend justification: Little is known about the population status of this species, or how it is affected by habitat degradation, but it is suspected to be undergoing an unquantified decline, owing to habitat loss to road construction and wildfires and other human pressures within its range.
