Diagnosis
In the Tetramorium solidum -group, there are five species with abundant hairs covering the dorsal surfaces of the whole body, namely, T. rothschildi , T. peringueyi , T. dichroum , T. margueriteae sp. nov. and T. brigitteae sp. nov. Tetramorium rothschildi is easily separated from other species by having branched hairs. Tetramorium dichroum can be easily distinguished from T. peringueyi and T. margueriteae sp. nov. by the absence of erect hairs on the antennal scapes. Tetramorium dichroum and T. brigitteae sp. nov. can be distinguished on the basis of the spine length: in T. dichroum spines are long and acute (PSLI 10–16) ( Fig. 4I View Fig ), whereas T. brigitteae sp. nov. has very short propodeal teeth (PSLI 6) ( Fig. 4J View Fig ).
