Diagnosis

In the T. solidum-group , only T. solidum and T. aisha sp. nov. have sparse hairs that are restricted to the mesosoma and the petiole; other species in this group either have abundant hairs covering the whole body or lack erect hairs. Tetramorium solidum has very long and acute propodeal spines (PSLI 17–20) ( Fig. 4K View Fig ), whereas the propodeal spines in T. aisha sp. nov. are very short (PSLI 5–9) ( Fig. 4L View Fig ).

Distribution

Only known from South Africa.

Remarks

Tetramorium solidum has been collected in Strandveld, Succulent Karoo, Fynbos and in transformed lands on tillite shales. This species has been recorded only in the Montane Fynbos and Renosterveld, Nama Karoo and Succulent Karoo; found nesting in clays soils, with craters of soil around nest entrances. Queens of this species were collected in April and males were collected in September from the nests. Seed stores have been found in nests. This species has been collected either by digging up nests or from pitfall traps and yellow pan traps.
