Tetramorium matopoense

Identification
Bolton (1980) - Tetramorium matopoense is easily recognized within the squaminode-group by its smooth pronotum coupled with the lack of hairs on the first gastral tergite. All other known species of the group have pronotal sculpture and gastral pilosity present.

Distribution based on Regional Taxon Lists
Afrotropical Region: South Africa, Zimbabwe.

Mandibles unsculptured except for scattered pits, anterior margin of clypeus with a shallow median notch. Frontal carinae sinuate and strongly developed. Antennal scrobes broad and shallow. Occipital margin in full-face view flat or at most only very feebly concave medially. Metanotal groove feebly impressed in profile. Propodeal spines strong, acute, broad basally. Petiole squamiform, the dorsal crest narrow but not knife-like, flat in posterior view. Postpetiole slightly antero-posteriorly compressed but by no means squamate, the dorsum evenly convex in profile. Clypeus without transverse rugulae. Dorsum of head feebly longitudinally rugulose, the spaces between them faintly superficially sculptured. Pronotal dorsum absolutely smooth, devoid of sculpture, the remainder of the dorsal alitrunk with weak and disorganized rugular and punctulate sculpture. Pedicel segments and gaster unsculptured, smooth and shining. Dorsal surfaces of head, alitrunk and pedicel segments with scattered long hairs which are quite stout and tend to be blunt apically, the head also with a number of shorter, finer hairs.
