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 Sao Paulo Tyrannulet from Phylloscartes paulista to Pogonotriccus paulista.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
