Iridomyrmex florissantius Carpenter, incertae sedis

Iridomyrmex florissantius Carpenter, 1930: 50.

Types. Holotype queen from the United States (Oligocene).

Comments. This species, based on a series of impression fossil queens, is only tentatively placed in Iridomyrmex as very little morphological detail is available. It is unlikely that this species is related to modern Iridomyrmex, but so little information is available that it is extremely difficult to determine its true relationships. As such it is retained in Iridomyrmex as incertae sedis with strong reservations that it actually belongs here.
