Population justification: The population is assumed to be very small, based on a paucity of records since its discovery in 1976, within its extremely small range. It is placed in the band 250-999 mature individuals here, equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: The population trend has not been estimated directly. The only threat known to the species is the loss and degradation of its habitat. Forest loss within the range has been negligible over the past ten years (Lane and Angulo 2018, Global Forest Watch 2020), and the species is currently not thought to be under threat (Lane and Angulo 208). Therefore, in the absence of evidence for any declines, the species is assessed as stable.
