†Formica luteola Presl, 1822

Radchenko et al. (2021) question the placement of this taxon within the genus Formica. They note that the body length of F. luteola is ca. 3.2 mm (too small for Formica), the body is light yellow (“Flavescenti-alba”) and the head is rounded and somewhat cordate (“Caput rotunda-tum, fere cordatum”). These features are not known to be present in either extant or extinct Formica species.

Distribution

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