Is this a different type of mite

Hi there I have a small spider mite problem kept in check with sprays and predator mites they are all but gone thankfully.. today I noticed what seems.to be a different mite you can see from the pics first two are two spotted mites but the other looks differnt possible.not even a mite what do you guys think?

I can add all the environment details if needed but not sure they are as it's just an identification issue! Cheers
