†Formica trigona Presl, 1822 |
Radchenko et al. (2021) question the placement of this taxon within the genus Formica. They note that F. trigona is too small for Formica (ca. 2.5 mm) with a triangular head (“Caput trigonium”) and long antennae (“antennae longitudine capitis et thoracis”). These features raise doubts that this species should even be included to the family Formicidae.
