Radchenko et al. (2021) question the placement of this taxon within the genus Formica. They note that based on the original description, F. quadrata cannot be unambiguously assigned to any ant genus, and we agree with its exclusion from Formica.



This taxon was described from Baltic amber, Baltic Sea region, Europe (Bartonian, Middle to Late Eocene).
