In the web interface, the map shown on each taxon page and within dialogs such as “Compare” and “Suggestions” has a button to choose the “Overlays”, and within that, there’s typically a checkbox to include pink squares to mark GBIF occurrences. Today, that went away. I assume this was disabled by a recent software change.
Thanks, I’m sorry I didn’t see the scientific name in your screenshots! I’m told it happens when our taxonomy and GBIF’s taxonomy isn’t mapped correctly (“mapped” meaning that we know the relationship of the taxa between the two databases). We’re not sure why that’s happening in some cases, but this particular example has been fixed. If you find another example, please let me know so we can investigate more throroughly.
I don’t know if what I experienced had the same cause as you’re seeing with arthropods. However, I would suggest it would be best to ask for that thread to be reopened as the context there will be more helpful than the context in this thread.
The issue you raise about this being a haphazard and labor-intensive manual process is very valid. Unfortunately I don’t know the answer. I do think you should file a bug report yourself. My issue was essentially fixed by using @bouteloua’s manual process and I don’t currently forsee that this is going to be a big task for me.
