Male. Stridulatory vein 2.9 mm long (Fig. 6), shorter than greatest width of pronotal disc in posterior area (3.6 mm). Stridulatory vein on underside of left tegmen with about 87 teeth (29.8 teeth per mm) of two different types: about half of the teeth large and well separated, the remainder in posterior area nar?row and densely arranged; a short transient zone in between (Fig. 12). Mirror of right tegmen very lit?tle wider than long (2.2 against 2.1 mm); distance between proximal heavily sclerotized vein and apex of mirror 2.7 mm; maximal width of dorsal tegmi?nal part behind mirror 1.9 mm (Fig. 9). Cerci 5.2 mm long (Fig. 20), with straight, rounded basal part which is slightly descending and slightly narrowed at end; in apical half curved mediad and external area triangularly compressed forming an acute angle (Fig. 22); before apex suddenly narrowed and strong?ly compressed forming a blade with acute tip. Sub?genital plate curved in an about 80°-angle (Fig. 17), upcurved area dived and apical parts deviating (Fig. 15). Phallic sclerite with long, stout furcae (Fig. 25), dorsal margin in lateral view sinuate, serrate; ventral apodeme present, keel-like (Fig. 28).
Coloration. Yellowish brown with a faint tinge of green (probably green when alive) and with contrast?ing dark brown markings. Head: Face with frons and eyes medium brown; genae and mandibles yellow; vertex dark brown with a short light stroke behind compound eyes. Antennae black with very sparse white annulation. Pronotum with disc dark brown with a short light stroke laterally at both sides at an?terior margin; lateral lobes yellow. Tegmen greenish yellow with piles of dark brown dots in cells; anterior margin, the narrow space between subcosta and ra?dius in basal half and including part of these veins, and all of the dorsal area dark brown; stridulatory vein on dorsal side of left tegmen blackish-brown; mirror on right tegmen transparent. Legs yellowish brown; fore and mid legs with ventral margin and apical third of femur and all of tibia and tarsus black?ish brown; hind leg with apical area of tibia and lat?eral areas of first and second tarsal segments and all of third tarsal segment dark brown. Apical margin of
tenth abdominal tergite in lateral areas, cerci except for apical blade, and apical area of subgenital plate dark brown.
Female. The single female at hand is not in good con?dition. Subgenital plate greatly notched in middle, resulting lobes acute-angular; external margin with a preapical tooth (Fig. 32). Ovipositor as in H. chinen?sis. Coloration as in male. Vertex with five light lines. Legs largely damaged. Epiproct with a black dot in ventro-basal area. Cerci dark brown from above, yel?low from below. Ovipositor medium brown with a dark brown band along ventral margin.
