Abstract. Myrmecia Fabricius is revised at species‐group level. Nine groups are recognized: those of M.aberrans, M.cephalotes, M.gulosa, M.mandibularis, M.nigrocincta, M.picta, M.pilosula, M.tepperi and M. urens . A key to the species groups is provided, and worker diagnoses, illustrations and species lists are given for each. Eight groups are constituted much as in the previous classification of John Clark, but defined using new characters. Phylogenetic relationships are investigated, with six cladograms derived from four sets of data, each with a different outgroup. The most plausible cladograms suggest that: (1) the aberrans group is the sister group to the others; (2) the pilosula, tepperi and mandibularis groups constitute a monophyletic assemblage, though monophyly of the first two is not confirmed; (3) the gulosa, nigrocincta, urens and picta groups constitute a monophyletic assemblage, though monophyly of the picta group is not confirmed; (4) the phylogenetic position of the cephalotes group is unclear.
