The genus Phylloscartes contains two clades that are rather deeply divergent genetically (Harvey et al. 2020); this divergence also largely corresponds to a suite of behavioral between species of the two clades. Therefore we resurrect the genus Pogonotriccus (type species eximius, Southern Bristle-Tyrant) for one of these clades, and revise the sequence of species of Pogonotriccus. Change the scientific name of Serra do Mar Tyrannulet from Phylloscartes difficilis to Pogonotriccus difficilis.
