Notes: Heer (1849, 1850) frequently appended the words Radobojana or Oeningensis to binominals, often to several separate species in a single genus, for example his Formica obesa, F. pinguis, F. pinguicula, F. macrocephala. The locality names do not constitute part of the taxon name, but rather indicate the geographical provenance of the material, either Radoboj (Croatia), or Oeningen (Germany). Thus F. obesa Radobojana indicates his material of this species from Radoboj, while F. obesa Oeningensis refers to his material of the same species from Oeningen.
