2. Margin of prosternal collar expanded and folded out into a large lip ( Fig. 3C View Figure 3 ); elytra round, almost heart- shaped ( Fig. 3C View Figure 3 ); declivous portion of elytra with little to no tubercles..................................... T. tschinkeli
- Margin of prosternal collar not expanded, only occasionally folded out; elytra round or elongate; declivous portion of elytra with tuberculate rows .........................................................................................................3
3. Disc of pronotum with prominent punctures ( Fig. 3D View Figure 3 ); gold setae present on elytra ( Fig. 3D View Figure 3 )..... T. herero
