Nothing is known about the biology of Tetramorium wagneri.
Identification
Bolton (1977) - This is the only known species of the ornatum-group which has a notched or impressed anterior clypeal margin and because of this it runs out in· the key close to the members of bicarinatum-group where such a notch is universally present. However, the sculpture, form of the propodeal spines and petiole identify wagneri as a member of the ornatum-group.

Description
Worker
Bolton (1977) - TL 3.8-4.8, HL 0.90-1.06, HW 0.78-0.96, CI 86-92, SL 0.70-0.86, SI 86-92, PW 0.58-0.70, AL 1.06-1.28 (25 measured).
Mandibles coarsely striate. Clypeus with a median notch or impression of variable size, small in some individuals. Maximum diameter of eye c. 0.18-0.20. Frontal carinae stretching back beyond the level of the posterior margins of the eyes but behind this commonly broken or interrupted, their place taken by the very strong longitudinal carinate rugae of the head. In some specimens the carinae continue unbroken to close to the occipital margin. Occipital margin of head conspicuously concave in dorsal view. Propodeal spines very long, narrow, acute and slightly downcurved along their length. Metapleural lobes short, acute and triangular. Peduncle of petiole very long and downcurved, the node in profile high and quite narrow, the tergal portion of the node higher than the dorsal length. Clypeus with five or more longitudinal carinae of approximately equal strength, the dorsum of the head very strongly and coarsely sculptured with regular, sharp longitudinal carinae of which there are about 10 (number varies between individuals) between the frontal carinae at the level of the eyes. Cross-meshes between these carinae are completely absent. Ground sculpture between the carinae consists of faint superficial punctulation, which in many is almost effaced. Dorsal ali trunk reticulate-rugose. Sides of petiole and postpetiole with sparse longitudinal rugae but these are much fainter on the latter than on the former, vestigial in some. Dorsum of postpetiole unsculptured or at most with faint superficial shagreening or punctures. Gaster unsculptured. Fine hairs present on all dorsal surfaces of head and body but those on the dorsal (outer) surface of the hind tibiae short, much shorter than the maximum tibial width, and subdecumbent or decumbent. Colour dark reddish brown to blackish brown, the appendages lighter.
