I've seen that picture multiple times and my feeling is that it's been color adjusted/enhanced. The closest I have seen to that would be a nice male notatus, but they won't show blue in the face. They will have deep yellow throats and chests with green-blue on the body and covered in black spots.
I can't wait...I'll take a pic when I can... may be a few days, as I am going to try to borrow a camera good enough to take a pic better than my phone can.

Actually, I have a severum that looks exactly like this, and have been trying to figure out what kind it is for several months, unsuccessfully. I have never seen any other photo of it online, no matter what I tried to search as, until this very thread. So it's good to know someone else has this odd looking sev. Mine has that exact bluish hue with the red spots. I would love to know what it is called, because it does not look like my turquoise sev at all. I'll be watching this thread develop for sure.
