T. cisti  covers North Africa, from Morocco to Libya (Tripolitania and Cyrenaica). Uvarov (1943) established that the type locality was Northern Tunisia. It is well characterized by a high pronotum keel, with deep transverse sulcus (mainly in males) ( Figs. 32–36View FIGURES 32 – 39), male epiphallus with apical lobes large and broadly separated ( Figs. 54View FIGURES 54 – 59 a, 55 a), spurs of hind tibiae long and slender ( Fig. 54View FIGURES 54 – 59 b). Tegmina are long and generally exceed the hind knees ( Figs. 42 –43View FIGURES 40 – 53, 55View FIGURES 54 – 59), hind wings are red inside with a central brown spot, which reaches the base of the red area, but this colour is very variable; for example in Tunisia yellow ( Djerba Is., Sousse), purple (Gafsa, Mareth, Gabes), blue (Skhira, Kerkenna Is.) and red tibiae (Korba, Biserte) have been found; in Libya bluish with red apex (Leptis Magna, East of Sirte), blue (East of Sirte, Agedabia) and vinaceous tibiae with red apex (Tagiura) have been detected; in Algeria red (El Kantara, Tebessa, Constantine) and yellow tibiae (Dumas) have been recorded. Concerning the length of tegmina, specimens with abbreviated wings exist in different localities (e.g., Kerkenna Is., Korba); generally, when tegmina are shorter than abdomen, hind wings are shorter than tegmina and show a simplified colour pattern (less coloured, with faint brown spots).

In the following paragraphs I will examine the different populations listed as subspecies by Eades et al. (2013).
