Bolton (1977) - This small species is a member of the angulinode-group, otherwise confined to the Ethiopian region. Its small size, unsculptured mandibles and short antennal scapes immediately separate it from all other Tetramorium with 11-segmented antennae in the regions at present under consideration.

Mandibles unsculptured, smooth and shining with scattered small pits. Frontal carinae extending back beyond the level of the posterior margins of the eyes. Antennal scrobes shallow but quite broad and long enough to accommodate the scapes; the latter short, with SI < 80. Pronotum in dorsal view with the corners sharply angulate. Propodeum with a pair of spines, the metapleural lobes triangular, upcurved, acute apically. Petiole in dorsal view with the node as broad as or broader than long, the postpetiole distinctly broader than long. In profile the node of the petiole a roughly rectangular block, usually slightly higher than long, with parallel and near-vertical anterior and posterior faces, and the dorsum flat to feebly convex. Postpetiole lower and rounded dorsally. Head and dorsal alitrunk predominantly longitudinally rugose but with scattered, smaller cross-meshes which are not as conspicuous. Petiole usually sculptured dorsally, only very rarely with this sculpture completely effaced. Postpetiole and gaster without sculpture. Hairs numerous on all dorsal surfaces. Colour light to mid-brown, usually with the gaster darker.
