Key to Dorylus subgenera workers

This key is based on Gotwald, W. H., Jr. 1982. Army ants. Pp. 157-254 in: Hermann, H. R. (ed.) Social insects. Volume 4. New York: Academic Press, 385 pp.

This subgeneric classification system was subsumed under the specie groups suggested in: Borowiec, M.L. 2016. Generic revision of the ant subfamily Dorylinae (Hymenoptera, Formicidae). ZooKeys. 608:1–280. doi:10.3897/zookeys.608.9427

The link for each terminal lug brings you to a list of species for the respective species-group.
