Yes, and this feature request might help a bit, but I’m not sure if that entirely addresses this particular situation. How do you inform the CV that not all the species are represented? That could theoretically be done with complete taxa where the full taxonomy is already added to the system, but it doesn’t really work with plants or insects where the mystery species might not even be in the iNat taxonomy yet.
If the CV knows a species, and based on the information it has, it’s confident that that species is the only species that looks like that, then it’s perfectly reasonable for it to suggest that species at species level. In most situations where it correctly identifies a distinctive species, it’s doing exactly the same thing. Like I wouldn’t want it to suggest higher taxa for Blue Jay or American Alligator. At least from the CV’s perspective it’s a coincidence that there happen to be unknown-to-it identical-looking species for a slug or a midge, and not for Blue Jay.
