The About section on taxon pages is pulled from Wikipedia through Wikidata, as per this request. This allows the same taxon to display different articles for different languages. However, if no article exists for a given language things can get wonky.
Another article with the same name is shown:
It displays EoL instead (often with issues):
There are currently several ways to address this:
- Leave the description correct in some languages but not others.
- Turn off the auto-description for all languages.
- Create Wikipedia pages whenever there is an issue.
I am proposing that if no Wikipedia article exists for a given language, the usual Wikipedia template should be displayed only for that language. Currently, it is only displayed if there is no Wikipedia page for any language, or if the auto-description is turned off. I have no idea how hard this would be to implement, but Wikidata already shows which iNaturalist taxon identifiers are associated with which language-specific pages. This can also be edited by anyone if there are any issues.
This may be in opposition to this implemented request, but that could be the reason why the wrong pages are showing up.
Another option would be to allow curators to turn off the auto-description for select languages.
