Specimen Labels

Based on collection records, this species is an inhabitant of open and semi-open areas (meadow, bushveld, woodland, etc.) and nests in the ground (from pitfall traps, under a rock, and as a ground forager).


Bolton (1980) - In the squaminode-complex of this group, T. do stands out as the only species in which the postpetiole is antero-posteriorly compressed and subsquamate. In other species of the complex the postpetiole is low and broadly rounded.

  • do. Tetramorium squaminode r. do Forel, 1914d: 224 (w.q.m.) ZIMBABWE. Raised to species: Arnold, 1960a: 82. See also: Bolton, 1980: 254.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Bolton (1980) - TL 3-0-3:2, HL 0:74-0:78, HW 0-68-0-74, CI 89-95, SL 0:50-0:54, SI 71-74, PW 0-52-0:57, AL 0-80-0-90 (8 measured).

Mandibles smooth and shining with scattered pits. Anterior clypeal margin with a shallow median impression. Anterior one-quarter of median portion of clypeus almost vertical, much more steep than the posterior three-quarters. Median clypeal carina bifurcated at the point where the clypeus turns down. Frontal carinae long and strongly sinuate, extended back almost to the occipital corners and surmounted by a very prominent raised rim or flange. Maximum diameter of eye 0-18-0-19, about 0-24-0-26x HW. Antennal scrobes shallow but broad and conspicuous. Propodeal spines long and strong; metapleural lobes low and acutely triangular. Petiole squamiform, in profile much higher than long and in dorsal view much broader than long. Postpetiole subsquamate, its node in profile strongly antero-posteriorly compressed and narrow, but lower and more broadly rounded above than the petiole. In dorsal view the postpetiole much broader than long and markedly broader than the petiole. Head with spaced out irregular longitudinal rugulae, with a narrow rugoreticular band occipitally. Spaces between the rugulae glossy, with only vestigial ground-sculpture which may be effaced in patches. Dorsal alitrunk irregularly rugose, generally with the longitudinal component predominant but most specimens with numerous or abundant cross-meshes on the promesonotum. Petiole, postpetiole and gaster unsculptured, smooth and shining. All dorsal surfaces of head and body with numerous fairly stout, blunted hairs, the majority of which are short. Scapes and tibiae with short decumbent pubescence only. Colour mid-brown, the gaster usually blackish brown.
