Two things...

I had a 0.2 colony because the dad was eating babies. So after a while I decided to introduce a male, after a few seconds the queen female started sniffing him then immediately attacked him, separated them and placed him back in his cage no harm done.

Prior to this, I was looking for males and came across this....
It is a 3.6 colony and I have no issues with mites, possible mosquitos but none of the others had this condition. Does anyone have a clue as to what is going on here?

If you're sure mites and fleas are not the problem, my second guess would be that it was just getting beat up. Most of the injuries I've seen due to aggression are on their rumps.

Also, as far as introducing a new male to the 0.2 girls you might have to cull that colony and start a new 1.2 trio. When they are baby free you could try completely disinfecting the whole enclosure and replacing all the bedding and any old food or chews/toys. Introduce the male after that and see if they accept him.

I have never noticed any aggression from their cage. I thought that may be it but wasn't sure.
I did introduce the male without cleaning the cage. I think it's time to retire the two females since their litters are down to 6-8.

Thanks for your input

That looks like bite marks to me.

I just checked everyone over and not one of them has the same marks. I was scared for a minute that there was some kind of bugs in there.
He is 1 of 3 males so I guess its safe to assume he is not welcome.

Thanks you two, I just wanted to make sure it was not some kind of genetics

Yeah, I wouldn't worry about mites. The look of that ASF is very indicative of territorial bite marks.
