I can’t remember if anyone posted a tool for doing this, but you could, within a couple minutes:
- export your observations
- take the column scientific_name and remove duplicates
- add the Wikipedia link brackets around the name (
=concatenate("[[",A1,"]]"), where A1 is one of the scientific names, apply to the whole column of names - copy/paste it into a subpage of your Wikipedia and see which ones are red links (don’t have articles)
See https://en.wikipedia.org/wiki/User:Hyperik/Ruth's_taxa for the red links.
Links might be red because that taxon has no article at all, or it could be red because it’s there but hosted at the name of a synonym.
