Iridomyrmex breviantennis

This is an impression fossil of a queen. There is so little morphological detail available that rigorous generic placement is nearly impossible. As such, and following Shattuck (1992), it is here left in Iridomyrmex but this placement is little more than speculation and it is considered incertae sedis in the genus.

Distribution
This taxon was described from France (Oligocene).
