I would not have said it was M. ruginodis as there is no spine on it.Will wait for one of the expert's as there is one on ant's.I did look in my BWARS members hand book and it seemed to tick the boxes.I know there a difficult one to ID without microscopic pictures.
Sorry I have just had another closer look at my photo's and the spine is clearly visible on the pedicel,so please accept my apologies for doubting your ID,that will teach me a lesson to look more closely in future.
The relevant spines are the two on the back of the propodeum, possessed by workers of all the Myrmica species. In M. rubra these are much shorter than in ruginodis. I am not sure that when you talk of 'the spine ... on the pedicel' you are looking in the right place. The pedicel is part of the antenna, and if you meant the petiole (the first of the two small waist segments) that is also not the right place.
The spines are clearly visible on the lowest ant in the first picture.

I can see it on the spine in first picture,I did mean petiole but still got it wrong so will carry on reading up on this subject.
