Thorax. Dorsal disc of pronotum rugose ( Figs. 10 View FIGURE 10 C–D). Dorsolateral and furcal sutures conspicuously marked and depressed ( Fig. 10C View FIGURE 10 ). Lateral lobes of mesosternum with apex rounded ( Fig. 10E View FIGURE 10 ). Metasternum diamond shaped ( Fig. 10E View FIGURE 10 ). Lateral lobes of metasternum rectangular with rounded apex ( Fig. 10E View FIGURE 10 ).

Wings. A pentagonal cell present between veins MP and CuA ( Fig. 11 View FIGURE 11 ). Vein CuA with four branches with bifurcations at apex ( Fig. 11 View FIGURE 11 ). Left stridulatory with basal teeth short, gradually increasing in length towards median region ( Fig. 12A View FIGURE 12 ). Median teeth slender, close to each other.
