Amethyst-throated Sunangel is split into three species, based on substantial vocal differences (Donegan et al. 2015) as well as differences in plumage. As a result, the polytypic group Amethyst-throated Sunangel (Longuemare's) Heliangelus amethysticollis clarisse/violiceps now is recognized as Longuemare's Sunangel Heliangelus clarisse, with subspecies violiceps and clarisse; the monotypic group Amethyst-throated Sunangel (Merida) Heliangelus amethysticollis spencei becomes Merida Sunangel Heliangelus spencei; and the polytypic group Amethyst-throated Sunangel (Amethyst-throated) Heliangelus amethysticollis [amethysticollis Group], with subspecies laticlavius, decolor, apurimacensis, and amethysticollis, retains the names Amethyst-throated Sunangel Heliangelus amethysticollis.
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.
