Justification of Red List category
This relatively recently described species is listed as Near Threatened owing to population declines that are suspected to approach 30% over 11 years (three generations), in particular on the basis of estimated annual declines of 13% in the adult population at Estação Ecológica de Águas Emendadas, Brazil between 2003 and 2007. The drivers of this decline are not well understood: this site is apparently well protected and has apparently suffered little anthropogenic alteration over the past 20 years since its formal protection. However, on the basis of apparent rarity in other large protected areas of cerrado, a population-wide decline qualifying it for uplisting is precautionarily suspected to have taken place.
