single lineage that evolved in the mid-Cretaceous period in Gondwana, so these subfamilies are now generally united into a single subfamily Dorylinae, though this is still not universally recognized. However, the unification of these lineages means that the only subfamily that is composed solely of legionary species is Leptanillinae, as Dorylinae contains many non-legionary genera. Accordingly, the "army ants" as presently recognized consist of legionary species in these genera: Subfamily Dorylinae (Aenictinae, Aenictogitoninae, Cerapachyinae, Ecitoninae and Leptanilloidinae, 2014) Aenictus Asphinctanilloides Cheliomyrmex Dorylus Eciton Labidus Leptanilloides Neivamyrmex Nomamyrmex Subfamily Leptanillinae Anomalomyrma Leptanilla Phaulomyrma Protanilla Yavnella Subfamily Myrmicinae Pheidologeton Subfamily Ponerinae Leptogenys (some species) Simopelta Subfamily Amblyoponinae Onychomyrmex See also "Leiningen Versus the Ants" – fanciful 1938 short story by Carl Stephenson about soldier ants swarming over a Brazilian plantation Notes References Bibliography External links A documentary by Carl Rettenmeyer of University of Connecticut: Associates of Eciton burchelli (2009) A documentary by Carl Rettenmeyer of University of Connecticut: Astonishing Army Ants (2009) Ants Insect common names
