Thank you Paul.

Is it possible, from these photos, to be absolutely sure?

Yes in my opinion you might be sure, because you can see the face, which is with out a black stripe and also you can see the femur 3 very well, which makes the differences between arbustorum (entirely black )and lineata (the bases are yellow). Hope you understand my English:)
