Bolton (1977) - This distinctive species appears closest related to Tetramorium carinatum but in that species the head is broader, the scapes shorter, the integument more densely sculptured and the meta pleural lobes are dentiform.
Two other New Guinea species, Tetramorium bicolor and Tetramorium tricarinatum, have the same distinctive coloration as diligens, but both of these species belong to the bicarinatum-group and hence have 12-segmented antennae and a dentiform sting-appendage.

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.
Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

Bolton (1977) - TL 3.8-3.9, HL 0.92-0.94, HW 0.74-0.78, CI 80-83, SL 0.96-1.00, SI 128-129, PW 0.62-0.66, AL 1.12 (2 measured).
Mandibles very feebly striate; antennal scapes long, SI> 120. Frontal carinae extended back only tothe level of the posterior margin of the eye and terminating in this vicinity. Scrobes virtually non-existent, merely a very shallow impression below the frontal carinae. Propodeal spines stout and very long, the metapleural lobes very reduced, low and broadly rounded, not dentiform, scarcely or not visible when the alitrunk is viewed in profile. Peduncle of petiole long, the node high and narrow in profile with a concave anterior face (Fig. 4). Dorsum of head mostly unsculptured, with one or two short rugulae between the frontal carinae, the median cephalic carina fading out posteriorly. Vertex unsculptured, smooth and shining. Dorsal alitrunk with a few coarse and widely spaced rugae, pedicel and gaster unsculptured. Bicoloured, the head and gaster blackish brown, the alitrunk, legs and antennae yellow. In the Syntypes the petiole is yellow-brown, the postpetiole darker, almost as dark as the gaster.
