Fore femur rather short, laterally compressed, with 4 to 5 spines on ventro-internal margin; fore tibia below tibial tympanum with strongly expressed angles; surface between angles rugose. Mid legs missing. Hind femur reaching or little surpassing tip of abdomen, moderately thickened at base, with five acute spines in apical area of ventro-external margin. Hind tibia with acute spines at dorso-internal and ventro-external margins, at dorso-external margin with minute spinules.
