Chapada Flycatcher was described in 2001 as S. islerorum, however it was later found that the type specimen of S. s. affinis was actually the same thing, therefore that name took priority. Note the pale tips to the tail feathers, a good feature to distinguish it from the similar Suiriri Flycatcher S. suiriri (previous). This photo was published in the first edition of Neotropical Birding.
