Population justification: The population size appears to be genuinely small (F. Angulo in litt. 2020). The population is estimated to number 250-999 mature 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 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: This species appears to have been lost from parts of its former range and is feared to be declining slowly, owing to habitat degradation and fires. The species's apparent rarity, occurrence in remote areas and low detectability, together with its tolerance of some degree of habitat modification, suggest that declines may be smaller than feared (F. Angulo in litt. 2020, S. Cuadros in litt. 2020).
