Ok, so I just tried to swap the old name of Sphinx geminus, which was still active on iNat with Lintneria geminus, which is the valid name of the taxon. I put the name Sphinx geminus as input and Lintneria geminus as output, filled all the citations and proceeded with the taxon swap.
What happened later does not have any sense to me. The taxon Sphinx geminus is still active and the taxon Lintneria geminus became a synonym to the genus Sphinx. Like… what? What did I do wrong and how can I undo this? I tried to delete the taxon swap, but it seems, that the change remained.
Please, help! I would like to do more swaps in the Sphingidae taxonomy as its often obsolete here, but now I am confused about how to do it correctly.
