Based on divergence estimates in Alström et al. (2011) and the phylogeny in Fjeldså et al. (2020:220), the genus of Neumann’s Warbler Urosphena neumanni and Pale-footed Bush Warbler Urosphena pallidipes is changed by WGAC to Hemitesia Chapin, 1948, as Hemitesia neumanni and Hemitesia pallidipes, respectively. The former aligns with Gill and Wright (2006, IOC v.1.0) and the latter with Gill et al. (2023, IOC v.13.2).

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.
