Material examined. CENTRAL AFRICAN REPUBLIC. Dzanga-Ndoki National Park , Ndoki, Lake 1, Light trap, 11–12.II.2012, P. Moretto (♂ holotype, ♀ allotype) ( BMCP) . La Maboké , M’Baiki I.1966, M. Pavan (1♀) ( MSNP) .

Measurements. Male. Body length: 30.5; pronotum length: 6.1; pronotum height: 7.0; hind femur: 28.0; tegmina: 49.6; tegmina width: 10.7. Female. Body length: 33.5; pronotum length: 6.0; pronotum height: 6.9; hind femur: 29.0; tegmina: 50.1; ovipositor: 5.5; tegmina width: 10.8 ( Massa 2013). Tegmina length/width: 4.6; tegmina width/pronotum length: 1.7–1.8.

Characters. Large species characterized by its purplish color ( Fig. 50 ). Lower margin of lateral lobes of the pronotum with a small concavity. Anterior margin of pronotum straight, posterior margin rounded. Fore coxae armed, fore tibiae dorsally furrowed. Stridulatory area of left tegmen well-developed, elevated above the wing plane and accentuated by a swelling of the rib; the stridulatory file consists of 70–75 evenly spaced teeth ( Fig. 71 ). Male cerci are long, sinuous, down- and in-curved, covered by sparse hairs, basally black and apically brown and slightly flattened, with round apices ( Fig. 105 ). Subgenital plate has a straight concavity, delimited by two apical apices, without styli. Fore femora are armed, hind femora ventrally with 9 black spines, surrounded by a wide black spot. Ovipositor short, gently curved and toothed at the apex of ventral and dorsal valves.
