Small earth ants; workers length 3-4 mm. They differ from similar species ( Tetramorium decem , Tetramorium venator ) in smaller sizes, one-color coloration and relatively smaller eyes. Shiny, slightly sculpted on top. Workers head length (HL) 0.62–0.70 mm, head width (HW) 0.48–0.58 mm. Head with subparallel almost straight sides. The main body color is light brown. The antennae of workers and females are 10-segmented. Antennal grooves well developed, long. The lateral parts of the clypeus are keeled raised near the attachment point of the antennae. Wide -angled mandibles with serrated chewing margin. The stalk between the breast and the abdomen consists of two segments: the petiolus and postpetiolus (the latter is clearly separated from the abdomen), the sting is developed, pupae are naked (without cocoon ). Posterothorax with 2 short and wide propodeal spines. The abdomen is smooth and shiny. Nest in the ground [1] .
Included in the species group Tetramorium decem species group. The species was first described in 1913 by the Swiss worldmecologist Auguste Forel ( Switzerland ) as part of the subgenus Decamorium as an irnfravid form of Tetramorium (Decamorium) decem var. ultor Forel, 1913 [2] . In 1922, in connection with raising the status of a subgenus to a separate genus (Wheeler WM, 1922), it was considered as part of it. In 2014, received a separate species status [1] .
