Mbanyana et al. (2018) - Tetramorium rothschildi was first placed in the genus Triglyphothrix because of its branched pilosity (Bolton 1976). After Bolton (1985) revised the status of Triglyphothrix, he placed this species in the T. solidum group because of the deep indentation on the anterior clypeal margin. Despite Bolton’s decision and our current treatment of this species as a member of the T. solidum group, we are not at all convinced that this species is a genuine member of the group. It is possible that T. rothschildi represents a convergent evolutionary lineage and the similarities in morphology are based on a similar granivore lifestyle. However, at present, it is not possible to address this question without a molecular phylogenetic framework.
