Population justification: This species is known from only one locality, where it is reported to be common. It may be more widespread, but a precautionary population estimate of 2,500-9,999 individuals is currently deemed appropriate. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification: Although the species is apparently tolerant of secondary habitats, it is likely to be negatively affected by human activities within its range, including total habitat clearance. It is therefore suspected to be declining, although probably not rapidly.
