Say species-A sensu lato is being split into species-A sensu stricto and species-B, which themselves are merely straightforward elevations of previously-existing subspecies-A and subspecies-B.
Say there are many identifications on iNaturalist of all three preexisting taxa. The following changes to IDs should happen:
- subspecies-A → species-A sensu stricto
- subspecies-B → species-B
- species-A sensu lato → split according to the atlases on species-A (s.s.) and species-B
This must be a very common situation. But I’m stuck. I can do step #2 but I can’t figure out how to do the rest. If I try to do step #1 first, I can’t, because it won’t let me activate species-A sensu stricto while species-A sensu lato is still active. If I try to do step #3 first, it won’t let me, because subspecies-A is still a child taxon of species-A sensu lato.
What I really want to avoid at all costs: Any solution that involves folding all the IDs of subspecies-A into species-A sensu lato. That would destroy the hard work of many identifiers.
Do I need to create a “dummy” species-C to temporarily contain the output of step 1?
I feel like I must be missing some order of operations detail here. Sorry in advance if it’s acutally super obvious!
