It is not possible to

It is not possible to identify this to species. It is a white-tailed worker, and as such could be either terrestris or lucorum s.l. The lucorum group always have pure white tails, terrestris workers may have tails anything from brown to white, and if white are not determinable. White-tailed males can only be done if you see the face (yellow in lucorum s.l., black in terrestris). And that does not go into the murky question of what exactly 'B. lucorum' is!

I have added two (poor) photographs to show the face to aid identification.

Thanks, but it does not help

Thanks, but it does not help - face colour is a feature only useful for males. It is one of these things you just have to accept - sometimes you can't separate terrestris and lucorum s.l. workers, even with a specimen.
