Specimen Labels

Nothing is known about the biology of Tetramorium rufescens.

Identification

Mbanyana et al. (2018) - The description of this species matches that of Bolton (1980), except for colour. We observed some variation in the specimens examined, ranging from red to light brown, in those collected at certain localities in South Africa (Klein Pella) and Namibia (Kamanjab, Luderitz District, Daberas, Hobatere, Epupa Falls).

The following character combination distinguishes T. rufescens from Tetramorium glabratum and Tetramorium signatum: dorsum of mesosoma with dense reticulate punctate sculpture and propodeal spines long and narrow (PSLI 16–23).
