Justification of Red List category
This species went undetected from 1938 to 2003, but was then rediscovered in gallery forest in Emas National Park, and has since also been found at several sites along the Alto Rio Juruena, and at Itiquira. Although the species's status remains very poorly known, it is likely to have a very small range, and an extremely small population, both of which are likely to be declining owing to habitat degradation. For these reasons this species is treated as Critically Endangered. Now its requirements are better understood, further searches may reveal that it is more widespread and common than was previously thought, in which case it may warrant downlisting in the future. Conversely, if the Alto Rio Juruena is confirmed as the global stronghold, planned hydroelectric developments could pose a massive threat to the continued survival of the species.
