Population justification: The species is uncommon in Bahia, Minas Geras and Espírito Santo, rare in Rio de Janeiro and restricted to a small site in Pernambuco (per D. M. Lima in litt. 2022). It is suspected that the total population numbers less than 10,000 mature individuals, with up to 1,000 mature individuals in each subpopulation, though it cannot be ruled out that the subpopulation in the Serra de Paranapiacaba may potentially be larger (ICMBio 2018, D. M. Lima in litt. 2022).

Trend justification: The population must have declined significantly, but it remains relatively common locally (Aleixo and Galetti 1997, A. Whittaker in litt. 1999, Develey 2004). It is suspected that declines are ongoing on the basis of deforestation and forest fragmentation. Over three generations (12.7 years), 9% of tree cover is lost within the extant range (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Given that the species is restricted to primary forest, population declines are likely to exceed the rate of tree cover loss as a consequence of additional forest degradation. Declines are therefore precautionarily placed in the band 10-19% over three generations.
