Description. Large species. Head: Face large, ovoid; forehead nearly smooth; fastigium verticis hardly wider than scapus; ocelli indistinct ( Fig. 12H ). Abdominal tergites two and three each with two rows of very small stridulatory pegs. Wings surpassing hind knees and reaching about middle of hind tibia ( Fig. 10C ). Tegmen: Radius with two branches, both forked near tip; media anterior fused in basal area with radius; media posterior absent; cubitus anterior forks between basal third and mid-length into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 4 anal veins. Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 7–9 external and 9–10 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides. Coloration. General color light brown (originally conserved in alcohol); disc of pronotum with hieroglyphic black figure; anterior and posterior margins narrow black. Vertex with a round black spot in middle and black bands on both sides. Legs light brown; genicular areas little darkened; anterior and lateral surfaces of fore tibia dark brown. Face yellowish brown with small black spots at lateral ends of clypeo-frontal suture, fastigium verticis with a large dark spot; antennal scrobae dark brown; scapus in part indistinctly infumate; tip of mandibles black. Tegmen yellowish transparent, veins hardly darker; hind wing transparent with dark bands along veins and veinlets. Male. Eighth abdominal tergite strongly prolonged behind. Ninth abdominal tergite ( type F in Brunner 1888 ) wide at base; dorsal apical margin prolonged into a short and narrow, setose projection with bifid tip; lateral area curved down, with both sides closing below the projection and forming in middle a stout elevation little widening towards tip and with subtruncate apex, in midline with a slight furrow; lateral areas of ninth tergite blackish brown, projection and central elevation pale ( Figs. 13 G–I). Subgenital plate wider than long with lateral margins convex and little upcurved; apical margin slightly bilobate; styli stout and long, inserted in about two thirds of plate length. Female unknown. Measurements ( 1 male ).—body w/wings: 50; body w/o wings: 31; pronotum: 7.5; tegmen: 39; tegmen width: 12; hind femur: 22; antenna: 140 mm .
