Hi! I’m new to both iNat, taxonomy and gastropods and had a question to learn a bit more on all three.
It seems that Arion subfuscus and Arion fuscus can only be distinguished anatomically through dissection, and can be considered a species complex. I can’t find any species A. fuscus/subfuscus species complex on iNat, though. I assume that this prevents many A. fuscus/subfuscus observations from reaching research grade and getting stuck at subgenus Mesarion.
Is there a reason for the situation or have I misunderstood something?
