Phylogeny of the West-Palearctic Aphaenogaster ants, including all the species-groups of the region as well as the tropical Deromyrma clade based on a Bayesian analysis of one mitochondrial (COI) and six nuclear (EPICs) markers. Support values represent Bayesian posterior probability values (PP). In the rightmost part of the figure, we present the new species-groups boundaries based on the interpretation of the phylogenetic results that is offered in the Discussion section.
