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

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