Head in full face view subtrapezoidal, wider behind than in front, with distinct, rounded posterior corners and weakly convex posterior margin. Eyes placed posteriorly and strongly bulging. Scapes moderately long. Mesosoma stout; in dorsal view all of its segments distinctly wider than long. In profile mesosoma convex at the level of anterior pronotum and postero-dorsal propodeum, and almost flat medially. Pronotal spines relatively well developed and strong, mostly anteriorly directed. Pronotum and mesonotum transversely evenly and weakly convex; propodeal dorsum humped medially and forming a stronger transverse convexity. Mesosoma distinctly marginate along its sides, the marginations not forming flanges or lobes. Promesonotal and metanotal sutures distinct but not impressed. Propodeal dorsum and declivity separated by a distinct margin. Propodeal teeth small, upturned and sharp. Petiole with four spines, the dorsal pair weakly diverging, directed upward and backward and about twice as long as the lateral pair; in frontal (or posterior) view the space between the dorsal spines almost straight with a very shallow convexity in the middle. First gastral tergite anteriorly concave.</paragraph>

The specimen from Tanzania is smaller and with slightly different indices. It also has shorter, toothlike pronotal spines, shorter lateral pair of petiolar spines, a less humped propodeum with a weakly convex margination between dorsum and declivity and almost lacks propodeal teeth; yet all of the remaining features well match those of the Kenyan specimens.
