I would say “look at literally any Agelenopsis observation in the northern US where I have submitted a disagreeing ID”, but on second thought, the example I gave is an issue of “a genus that is unidentifiable to species in only part of its range.” That is a phenomenon that, as far as I can tell, the CV model completely fails to take into account.
However, that is a separate issue from the inconsistent geomodel maps that are the original motivation of this thread.
