FIGURE 1. Phylogenetic relationships in the Pseudomyrmex ferrugineus group and related species, based on maximum likelihood (ML) analysis of 1,672 UCE (ultra-conserved element) loci (from Ward & Branstetter 2017). Bootstrap support is 100% at all nodes except the two whose support values are shown. Obligate acacia-ants are in red font, and can be seen to comprise two clades within the P. ferrugineus group. Two species (P. ferrugineus, P. mixtecus) are paraphyletic, consistent with a recent origin of their sister species by peripatric speciation (Ward & Branstetter 2017). The P. goeldii group is represented by three of its five species: P. laevifrons, P. micans and P. obtusus.
