I'm fine with this swap, as it keeps iNat aligned with molluscabase (where the change was made last month), and both now aligned with the Mussel Project.
However, I am puzzled as to why molluscabase made the change they did.
Of all of the references cited on any of the molluscabase pages for Paxyodon, Prisodon, Pa. syrmatophorus, and Pr. syrmatophorus, only two are not original descriptions dating from 1857 or earlier. One of the new ones is to the Mussel Project's 2019 database listing. The final one is to the 2016 article "Genetic relationships among freshwater mussel species from fifteen
Amazonian rivers and inferences on the evolution of the Hyriidae" by Santos-Neto et al. It states "our data agree with the proposal of Bonetto (1967), which classified T[riplodon] corrugatus, P[risodon] obliquus and P[axyodon] syrmatophorus into three distinct genera." https://doi.org/10.1016/j.ympev.2016.04.013
Maybe I should just refrain from doing armchair taxonomy.
Sometimes it's hard to find what they were actually referencing, and sometimes it seems to be the opinion of a certain curator. Might be worth reaching out to the most recent editor.
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.
