Radchenko et al. (2021) question the placement of this taxon within the genus Formica. They note that F. macrognatha is quite small (ca. 3.7 mm), with short legs (“Pedes breves”), and its head is large and triangular (“Caput… magnum, trigonum”), precluding its placement in Formica.



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