- thalidum. Tetramorium thalidum Bolton, 1977: 141, fig. 70 (w.) AUSTRALIA.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Holotype. TL 3.2, HL 0.80, HW 0.72, CI 90, SL 0.54, SI 75, PW 0.58, AL 0.92.
Mandibles longitudinally striate, median portion of anterior clypeal margin without a notch. Frontal carinae extending back almost to the occiput but becoming indistinguishable from the surrounding sculpture before reaching it. Antennal scrobes long, broad and shallow but their limits clearly defined and the area which they occupy shallowly concave. Eyes of moderate size, maximum diameter c. 0.18, about 0.25 x HW and with a few minute hairs projecting from between the facets (easily abraded away). Eyes situated approximately at the midlength of the sides of the head, the occipital margin very broadly concave. Metanotal groove not impressed, scarcely or not visible in profile. Propodeal spines stout and acute, metapleural lobes elongate, narrowly triangular and feebly upcurved. Node of petiole in profile with anterior and posterior faces parallel and more or less vertical, the dorsal surface evenly, gently convex. Dorsum of head evenly and quite regularly longitudinally rugulose, the spaces between rugulae densely but finely reticulate-punctate. Dorsal alitrunk predominantly longitudinally rugulose with densely punctate spaces except on the pronotum where a rugoreticulum is present. Petiole and post petiole finely but irregularly rugulose and densely finely punctate. Base of first gastral tergite with fine superficial puncturation or shagreening. All dorsal surfaces of head and body with numerous erect or suberect hairs which are very short, stout and usually blunted on the alitrunk. Colour orange-brown, the head somewhat darker in shade than the remainder.
Paratypes. As holotype, with dimensions TL 2.9-3.2, HL 0.74-0.80, HW 0.70-0.76, CI 90-95, SL 0.52-0.58, SI 74-77, PW 0.54-0.62, AL 0.90-0.98 (5 measured).
