Tetramorium glabratum looks similar to T. rufescens in that 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, whereas these are long and narrow in T. rufescens (Mbanyana, 2013)
