- Petiolar peduncle not clearly differentiated from the node......................................................2

2. Foveae on lateral pronotum widely separated, sparse and irregularly placed; inter-foveal distance more than diameter of foveae ( Fig. 12View FIGURE 12); erect hairs restricted to the anterior pronotum, rest of the mesosoma devoid of any hair. Peninsular Malaysia ... T. rex 

- Foveae on lateral pronotum more closely spaced, denser and more regular; inter-foveal distance less than the diameter of the individual foveae; whole mesosoma bearing hairs............................................................3

3. Foveae on lateral pronotum contiguous ( Fig. 12View FIGURE 12); whole mesosoma covered in erect hairs. Sri Lanka............ T. legatus 

- Foveae on lateral pronotum never contiguous, inter-foveal distance less than foveal diameter but more than the radius of the individual foveae; erect hairs occupying the entire pronotum and grading to decumbent and appressed towards the propodeum.
