Tetramorium solidum

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. (Mbanyana et al. 2018)

Identification
Mbanyana et al. (2018) - In the T. solidum-group, only T. solidum and Tetramorium aisha 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), whereas the propodeal spines in T. aisha are very short (PSLI 5–9).

Distribution
Tetramorium solidum has been recorded from South Africa (Western Cape and Northern Cape) in Strandveld and transformed lands on tillite shales.

Distribution based on Regional Taxon Lists
