1. Taxa from Africa...................................................................................... 2

- Taxa from Madagascar and Indian Ocean Islands ............................................................. 6  

2. Tibial spurs right-angular, with prominent internal flange ( Figs 4, 5 View FIGURES 3–6 ); biaereolate cells present in costal area of forewing before Rs ( Fig. 3 View FIGURES 3–6 ); abdomen with chevron-like pattern ( Fig. 11 View FIGURES 10–12 ). Eastern African coastal belt, South Africa to Somalia............................................................................................. S. longicornis (Rambur)   .

- Tibial spurs not sharply bent at a right angle, more evenly curved and lacking prominent triangular flanges............... 3

3. Biaereolate cells absent from costal area of forewing before Rs and rarely present before Rs2 ( Fig. 27 View FIGURES 27–30 ); unbroken series of biaereolate costal cells only commencing beyond Rs2; tibial spurs slender, strongly curved (but not bent at right angle), with slight flange in forelegs ( Figs 28, 29 View FIGURES 27–30 ); Central, South and Eastern Africa........................... S. medialis   sp. nov.
