What about Alvus Animus, I am not great at latin but a quick google translate shows the following:

• Alvus - can broadly be translated to Hive (hint, don't let the word bowel fool you 😅)
• Animus - Latin for Mind is Animo, I felt that didn't roll that good, and took the liberty to change it to animus.

So ultimately it would be Hive Mind, Hive is pretty self-explanatory and Mind because we are the people of the mind, we think for the sake of thinking and the fundamental truth of our nature.

So yeah, my suggestion is: Alvus Animus.
