Hmm I'll try to get a better picture and post it here.It does not look like eupterus to me. The pattern looks wrong. The dorsal shape and absence of trailers looks wrong.
It'd be easier to guess if we had full body shots but the syno experts on PCF would likely tell you even with these shots, UNLESS it is a hybrid... then again, full body shots would be needed, I think.
My impression from staring at it is that it looks a genuine species to me.
