Male characters. Tegmina: fully developed, without subcosta lobe.—Femur armament: femora of all legs with an apical spine.—Tibia armament: number of apical spines on the fronttibia either seven [1.7.2] or eight [1.8.0][n.7.n][n.7.n] (see discussion under I.5.B).According to Chopard (1929) and Bey-Bienko (1950) the armament of the fronttibia should be the same in all species [1.7. 1]. The pretended ventral spine (in bold) is in my opinion situated on the dorsal surface, though near to the border between the ventral and dorsal side of the tibia.—Subgenital plate: strong bristles distributed only along the posterior margin, styli present, Fig. 17B .—Right phallomere: Type 4, Fig. 15H .—Supraanal plate: very short, slightly convex, Fig.17A .—Cercal tricholiths:>5 per anulus, Fig. 18I.
