Diagnosis

Tetramorium jordani is the only species in the Tetramorium solidum group with the combination of no propodeal spines (the propodeum is only angulated with PSLI 1–3) and a hairless body ( Fig. 3G View Fig ). The only other species without propodeal spines is T. brigitteae sp. nov., which has erect hairs covering the entire body.

Distribution

This species has been recorded from arid regions of South Africa (Western Cape and Northern Cape) and Namibia in the following habitats: Succulent Karoo, Namib Desert, Lowland Fynbos and Renosterveld, Montane Fynbos and Renosterveld and Nama Karoo.

Remarks

Tetramorium jordani nests in sandy soils, with nests located either at the base of plants or with the entrance in the open, away from plants. The nest usually has a crater of soil around the entrance. In sand dunes of the Namib Desert, the tunnels inside the nest have crust-like walls to stop sand from falling in, and the entrance of one nest observed was funnel shaped due to the crust-like lining and the fact that the loose sand around the entrance was blown away by the wind. The species has been collected using yellow pan traps, pitfall traps and hand collecting. Tetramorium jordani feeds on seeds.
