Thanks for notifying about this. This isn’t really a bug per se, just the auto-description routing to the wrong article because there are multiple ‘Acar’ articles on Wikipedia. Simple curation fix by specifying that the linked article should be ‘Acar (bivalve)’, which I’ve done now.
Heads up for future, best way to report on these is to flag the taxon directly; head to https://www.inaturalist.org/taxa/196283-Acar, and then use the curation button at the top right of the map.
Thanks again, will close now that it’s resolved :)
