The name Leucolia proposed for a clade of emerald hummingbirds (Stiles et al. 2017) was found to be preoccupied, and a new name Ramosomyia was thus proposed (Bruce and Stiles 2021). Violet-crowned Hummingbird Leucolia violiceps thus becomes Ramosomyia violiceps and Green-fronted Hummingbird Leucolia viridifrons becomes Ramosomyia viridifrons, aligning with Chesser et al. (2022) and Gill et al. (2022, IOC v.12.2).

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.
