Tetramorium depressum

From 20 to 1300m although big, populous nests are found at the higher altitudes, usually under stones. The few nests located in the drier coast seemed to be in a miserable and suffering state, with a small number of workers. But for a smaller size the morphology of lowland populations was indistinguishable from other populations. (Espadaler 2007)
