Key to the species of Tropostreptus  

The key is valid for adult males only.

1. Metaplica apically with three processes including the long apico-lateral process. Body diameter> 8.5 mm ................ 2

- Metaplica apically with one or two processes including the long apico-lateral process. Body diameter usually <8 mm ...... 3

2. Lateral proplical lobe (lpl) relatively small; antetorsal process (atp) of telopodite curving basad(-laterad) ( Figs 14 View FIGURE 14 , 15 View FIGURE 15 A)................................................................................................... austerus  

- Lateral proplical lobe very large; antetorsal process of telopodite curving basad-mesad ( Fig. 15 View FIGURE 15 B)................. severus  

3. Apico-lateral process of metaplica strongly reflexed. Body diameter 4.5–6.3 mm ................................... 4

- Apico-lateral process pointing more or less laterad, not reflexed. Body diameter 6.0– 8.8 mm .......................... 5

4. Latero-basad metaplical process blunt; antetorsal process of telopodite long, strongly curved ( Fig. 7 View FIGURE 7 E); body diameter 5.4–6.3 mm ............................................................................................ droides
