Population justification: There are very few recent records (J. Eaton in litt. 2016) and based on an assessment of known records, range size and descriptions of abundance this species may have a population size in the band 250-2,499 mature individuals, with <250 mature individuals per possible subpopulation.

Trend justification: A very rapid and on-going decline is suspected, owing to habitat loss and degradation.
