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 Variegated Bristle-Tyrant from Phylloscartes poecilotis to Pogonotriccus poecilotis.
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.
