DIAGNOSIS. The male of this species is well characterized by the apical lobe of hind tibiae being distinctly shorter than that of the other species. The last antennal segment is bent. The apical margin of S5 is glabrous and slightly curved in the middle. The metasoma is black with grey setae. Some black specimens of T. petersi ( var wissmanni ) may be confused with T. kandti but they differs by the shape of the apical lobe of the tibiae and the S5 ( fig. 9 ).

The female is always black with grey pubescence (fig. 34). It is difficult to separate it from T. productum .

VARIATION. The male metabasitarsi are black apically and pale yellow basally (type T. kandti and most specimens) or totaly black (Kikombo).
