The type [[genus]] is ''[[Formicium]]'' with the genus ''[[Titanomyrma]]'' being described in 2011.  ''Formicium'' includes the described [[species]] which are known from fossil wings only.  ''Formicium'' is known from three species.  ''Formicium mirabile'', named by [[Theodore Dru Alison Cockerell|Theodore D. A. Cockerell]] in 1920, and ''Formicium brodiei'', named by [[John Obadiah Westwood|John O. Westwood]] in 1854, are both known from [[Wing (insect)|fore wings]] found in the [[middle Eocene]] of [[Bournemouth]], [[Dorset, England]].<ref name="Archibald2011"/>  The third species named, ''Formicium berryi'' was named by [[Frank M. Carpenter]] in 1929 from the middle Eocene [[Claiborne Formation]] in [[Puryear, Tennessee]], USA, though he misidentified the formation as the [[Wilcox Formation]].  ''F. berryi'' was the first described occurrence of the genus and, until 2011, the subfamily, in North America.<ref name="Archibald2011"/>   With the description of ''Titanomyrma'', the two species already described from complete body specimens, ''Formicium giganteum'' and ''F. simillimum'',  were transferred to the new genus as ''Titanomyrma giganteum'' and ''T. simillimum'' respectively.  ''Titanomyrma'' also contains a third species, ''T. lubei'' described in the same paper as the genus and which is the second member of the subfamily known from North America.<ref name="Archibald2011"/>
