Formica

A large holarctic genus that are common in many northern temperate areas. For many reasons this genus as a whole has many well studied species. The taxonomy is fractured into many smaller subdivisions (both subgenera and species groups; see Formica species groups), many of which have no official taxonomic designation and are poorly delineated. In some cases older group names have been replaced by newer names, and new arrangements of species, but the older groups remain in use by some myrmecologists and not others.
