Systematic revision and phylogeny of the genera Blakeius Ashmead, 1903 and Liomutilla André, 1907, with description of two new genera (Hymenoptera: Mutillidae, Myrmillinae).

Nine species of Palaearctic Myrmillinae with females bearing two round spots on the second metasomal tergite, currently assigned to two genera, Blakeius Ashmead, 1903 and Liomutilla André, 1907, are revised and their phylogenetic relationships are investigated. The cladistic analyses demonstrate that Blakeius is not strictly monophyletic but includes three distinct lineages: Blakeius s. str.
