I go for Besra.  There is no way a male that is at least as old as a second winter to show such clear Mesial stripe.  Also, I think the bars on the tail also fit Besra.  They are very clear and the dark/light ratio is close to 1:1.  In Japanese, they are not that clear and the dark/light ratio is close to 1:2.
