Description: 

Used to distinguish Tetramorium simillimum from Tetramorium caldarium, but can be very subtle and difficult to observe. In the former species, the antennal scrobe is more strongly impressed, and the frontal carina remains a distinct outside border of the scrobe, even at its most posterior section.
