Population justification: This species has now been recorded from three locations with a minimum of 14 individuals known from Pindobas IV and Mata do Caetés, and confirmation that it occurs in Augusto Ruschi Biological Reserve. Additional forest occurs adjacent to these known sites which requires further survey work; hence the population is estimated at 50-249 individuals. This equates to 33-166 mature individuals, rounded here to 30-200 mature individuals. However, if further work either locates the species at additional sites or supports the assertion of Venturini et al. (2005) that the population may number fewer than 50 individuals, this estimate will require revision.
Trend justification: The species is suspected to be declining at a rate of 10-19% over 11 years (three generations), as a result of ongoing forest clearance owing to conversion to coffee plantations, mining activities and subsistence usage.
