Diagnosis . Tegmina with an pentagonal cell present between veins MP and CuA ( Fig. 11 ). Cercus apex acute, with spine rounded ( Fig. 10K ). Lateral lobes of mesosternum anteriorly parallel, posteriorly curved outwards, with rounded apex ( Fig. 10E ). Description. Male. Head. Smooth Fastigium elongated, anteriorly bilobed in dorsal view ( Fig. 10C ). Vertex triangular, with superior portion bilobed, with large, rounded parallel lobes in frontal ( Fig. 10B ). Thorax. Dorsal disc of pronotum rugose ( Figs. 10 C–D). Dorsolateral and furcal sutures conspicuously marked and depressed ( Fig. 10C ). Lateral lobes of mesosternum with apex rounded ( Fig. 10E ). Metasternum diamond shaped ( Fig. 10E ). Lateral lobes of metasternum rectangular with rounded apex ( Fig. 10E ). Wings. A pentagonal cell present between veins MP and CuA ( Fig. 11 ). Vein CuA with four branches with bifurcations at apex ( Fig. 11 ). Left stridulatory with basal teeth short, gradually increasing in length towards median region ( Fig. 12A ). Median teeth slender, close to each other. Left stridulatory file with 83 teeth, length of 3.4 mm and greatest width of the vein of 0.5 mm ( Fig. 12A ).

Mid tibia slightly widened basally, with four ventral spines ( Fig. 10G ). Hind femur with eight ventral spines, wider basally ( Fig. 10G ). Abdomen. Cercus inward curved, apex acute, with small rounded projection ( Fig. 10H ). Subgenital plate trap- ezoidal, with length surpassing half the length of cerci ( Fig. 10I ). Apex of subgenital plate emarginated ( Figs. 10 I–J). Stylus rectangular and short ( Figs. 10 I–J). Cercus and subgenital plate covered with numerous bristles ( Figs. 10 I–K). Internal male genitalia . Not examined. Coloration . Based on photos of preserved specimen ( Fig. 10 ) General coloration yellowish-brown. Compound eyes brown. Female. Unknown.
