s. carnaria seems to be still suggested by the current model.
For example, this observation will suggest it if you include “species not seen nearby.”

I agree with Bouteloua that perhaps people haven’t kept up with bumping the new s. carnaria observations to a higher level.
One possible reason why you noticed an improvement was perhaps connected to when iNat switched from having the default CV suggestions be only those that were seen nearby. Users can still toggle that off though and get the CV suggestions not seen nearby.
I do have a open feature request to label species that are included in the current CV model (to remove all doubt about situations like these), but it hasn’t gained that much traction.
