"Nothomyrmecia" and other primitive ant genera such as "Amblyopone" and "Myrmecia" exhibit behaviour similar to a clade of soil-dwelling families of vespoid wasps.The following cladogram generated by Canadian entomologist S. B. Archibald and his colleagues shows the possible phylogenetic position of "Nothomyrmecia" among some ants of the subfamily Myrmeciinae.
