fossil genera; 2 tribes[1] Myrmeciinae is a subfamily of the Formicidae, ants once found worldwide but now restricted to Australia and New Caledonia.

[3] An additional three genera, one form genus, and 9 species were described in 2006 from the Early Eocene of Denmark, Canada, and Washington.

The Late Aptian Crato Formation genus Cariridris was sometimes included in Myrmeciinae, but it has is now usually classified within Ampulicidae.

Two undescribed specimens in the Staatliches Museum für Naturkunde Stuttgart are known, suggesting a myrmeciine affinity.

[6] The subfamily Myrmeciinae was established by Italian entomologist Carlo Emery in 1877 under the original name Myrmeciidae.
