Distribution

This species is known from Ethiopia, Tanzania, Kenya and Ghana.

Remarks

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. This species has been recorded from Ethiopia, Uganda, Kenya, Ghana and Tanzania. Tetramorium rothschildi has been found nesting in red laterite soils; nests sometimes have grass husks around the entrance. Pitfall traps and hand collecting methods have been used to collect this species.
