Stella’s Lorikeet C. stellae is splitfrom West Papuan Lorikeet Charmosyna papou(Clements 2007:135)
Summary: The beautiful West Papuan Lorikeet is a newly recognized endemic bird for the Bird’s Head of western New Guinea, while Stella’s Lorikeet is widely distributed in the remainder of the island.
Details: Charmosyna stellae was described as a separate species long after C. papou was made known to science, but was for many years treated as a subspecies group (e.g., Hartert 1930, Peters 1937). Voisin and Voisin (1997) and Beehler and Pratt (2016) considered the several striking and consistent plumage differences between the isolated Vogelkop nominate C. papou and the other forms long considered conspecific to be indicative of species status. They are substantially genetically diverged (Joseph et al. 2020, Smith et al. 2023), hence the WGAC and Clements et al. (2023) now agree with HBW and BirdLife International (2022) and Gill et al. (2021, IOC v.11.2) in treating them as two species.
English names: The English name West Papuan Lorikeet better describes the distribution of Charmosyna papou and avoids the potential confusion engendered by use of the name Papuan Lorikeet, given the specific epithet and previous usage when both taxa were united. The widely familiar name Stella’s Lorikeet for the widespread C. stellae is unchanged; it has been in use since at least Iredale (1956), Forshaw (1973), Sibley and Monroe (1990), and Juniper and Parr (1998). These names also align with Pratt and Beehler (2015), Beehler and Pratt (2016), Gregory (2017), and Gill et al. (2021, IOC v.11.2).

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.
