Hind tibia armed dorsally with numerous spines, often alternating in lengths (Fig. 5I); apex with a pair of small subapical spurs; ventral spurs more elongate and more apical in position. Prothorax with spines very slender, widely separated; meso- and metathoracic processes short, knob-like. Tegmen short, (Table 1, Fig. 5F), stridulatory file positioned on blister. Cercus (Figs 5D, E) robust, apically acute and curving, internal margin with a stout spine and an excavation; base of cercus with a short slender projection (Fig. 5E) directed inwards, surface clothed with stiff brown setae.
