Recently, someone alerted me about a taxon split performed on the genus Eurema and i noticed that in this observation:https://www.inaturalist.org/observations/16253414 that IDs of Eurema were all replaced with a lower level subfamily ID due to the split.
Why does this happen?
I’m not too familiar with taxon splits as i’ve never done one myself but shouldn’t the generic level IDs be kept? Why is there a need to downgrade it to subfamily?
My only guess is that the system doesn’t know which one of the newly split genera the “old” Eurema ID was referring to so it played safe by choosing a subfamily-level ID containing both.
