Really? She looks smaller than the other umbratus queens I have found.

[Nathant2131]

7 mm would be correct.

7 mm would be correct.

Ok thanks, but if you don't mind could you please tell me what species are compatible? I read that they need to be from the niger group but I am unsure which ants that includes.

[Nathant2131]

That would be Lasius neoniger, Lasius alienus, or Lasius pallitarsis. However flavus-group has been used in introduction which includes Lasius flavus and Lasius nearcticus.
