Radchenko et al. (2021) question the placement of this taxon within the genus Formica. They note that F. gibbosa is too large: ca. 10.5 mm, its head is ovoid (“ovoideum”) and the mesosoma is extremely elevated (“Thorax ovoideus, eximie elevates”).



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