Diagnosis
Tetramorium glabratum is similar to T. rufescens. They both lack pilosity on the dorsum of the mesosoma and on the first gastral tergite and are both reddish coloured. Tetramorium glabratum can be distinguished from the latter by the short and broad propodeal spines (PSLI 4–8) (3H), which are long and narrow in T. rufescens (PSLI 16–23) (Fig. 3I).
