It was only described in 2001. Up till then it was assumed to be a Suiriri
Flycatcher Suiriri suiriri
The reference is:
Kevin J. Zimmer, Andrew Whittaker & David C. Oren,
"A cryptic new species of flycatcher (Tyrannidae: Suiriri) from the cerrado region of central South America
The Auk 118, 1 (2001): 56-78 |
 |
It is found in the same areas as Suiriri Flycatcher but can be distinguished by its proportionally smaller bill
and broad bolder pale terminal tail fringe.

"The generic name is derived from Tupí, an indigenous South American language: from gûyra
(bird) and memûa (cheater, trickster). We choose this name for the genus because its only species "tricked" ornithologists
three times before we could clarify its specific name, taxonomy, and systematic position. The first trick was hiding in plain sight as ornithologists
failed to recognize that two similar-looking species occurred side by side in the Cerrado, even though there was evidence of this since Allen (1889)
[Bull. A.M.N.H., 2, 183-208]. The second time was when Zimmer et al. (2001) [Auk, 118, 56-78], after accurately pointing out that two cryptic species
occur syntopically in the Cerrado, missed the chance to correctly use the name proposed by Burmeister. The third time was when the Chapada Flycatcher
was inadvertently included in the genus Suiriri. One and a half decades of additional research was necessary for the Chapada Flycatcher to be
correctly classified." (Lopes et al. 2017) |

It also has a different voice and has a distinctive wing and tail shivering display that you can see in photos 2,
3 and 5.
The birds in photos 1 to 4 were recorded by Jeremy Minns.
