Taxonomy

This species was formerly placed in the genus Suiriri. It was move to its own newly erected genus Guyramemua based on a molecular phylogenetic study published in 2017.[2][3]

Description

It closely resembles the suiriri flycatcher of the subspecies affinis, and was included within it until being described in 2001.[4] Compared to it, the Chapada flycatcher has a broader pale tail-tip, a slightly shorter bill, and a different voice. It also has a distinctive wing-lifting display, which is lacking in the suiriri flycatcher.

Distribution and habitat

It is found in the cerrado of south-central Brazil and adjacent far eastern Bolivia.

Status and conservation

The first time the chapada flycatcher was included on the IUCN Red List was 2004; at that time, it was considered a species of least concern. By 2009, however, its status had been uplisted to near threatened, as annual surveys in part of its core range showed dramatic declines of more than 30% over an 11-year period. The reasons for the decline are not well understood.[1]
