    In the assessment of the risk of extinction of Brazilian fauna carried out in 2019, the species was categorized as Least Concern (LC) (CEMAVE/ICMBio, 2019).

    Evaluators: Caio Graco Machado Santos, Ciro Ginez Albano, Glayson Ariel Bencke, José Fernando Pacheco, Luís Fábio Silveira, Vítor de Queiroz Piacentini and Wagner Nogueira Alves.

    Criterion A – cannot be applied as long-term population estimates data are not available to track the decline by observed data (a) and the decline in AOO and EOO (c) do not reach the thresholds for a threat category. Habitat loss calculations performed with tools available on MapBioma (https://mapbiomas.org/) between 2006 and 2019, was 5.3% in three generations.

    Criterion B – not applicable, as the calculations of AOO and EOO (142,424 km2) do not reach the thresholds for categorizing threatened and do not meet at least two of the sub-criteria.

    Criterion C – there is no data, observed, estimated, projected and inferred on the number of mature individuals and respective population decline.

    Criterion D – there is no population data on mature individuals and it is not a small and restricted population.

    Criterion E – there is no PVA data.

    Habitat loss can be a threat (Hinkelmann, 1999). However, such a threat is not capable of putting the species at risk of extinction in the near future.
