Bioacoustics of Kansua diebua

Description. Holotype . Female. Head, vertex of frontis, vertex of fastiguim, compound eyes, occiput, and pronotum similar to that of Kansua hummeli . Tegmen extending behind middle, up to the seventh abdominal tergum, widened beyond the middle, with obliquely rounded apex; radial veins running along the subcostal vein in the middle; median veins running distantly from the radial veins from the middle to posterior margin ( Figs. 1 F,H, 2H). Hind wings rudimentary, about two thirds of length of tegmen. Fore femur with 5 small spines on interior ventral margin. Median femur with 5 small spines on both ventral margins. Hind femur with 8–9 small spines on both margins. Fore tibiae with 2–4 exterior on dorsal margins and 6 spines on both ventral margins. Median tibiae with 2 interior and 4 exterior spines on dorsal margins, and 6 spines on both ventral margins. Hind tibiae with 9 spines on both dorsal margins and 16 spines on both ventral margins. Subgenital plate slightly wider than long, approximately trapezoiform, with a sulcus along middle; caudal margin with an obtuse angular excision; lobes short, round. Ovipositor decurved, much longer than hind femur ( Figs. 1 F,H, 2H). Male. Tegmen amplified, extending sixth abdominal tergum, with clear longitudinal and cross veins; dorsal plane broad in basal half, gradually narrowed distad; lateral plane broadened and deepened, deepest in apical one sixth, with wide rounded apical margin ( Figs. 1 E, 2A,E). 2/3 basal part of stridulatory file on underside of left tegmen with 31 distinct stridulatory teeth and 1/3 apical part with about 20 indistinct small teeth. These teeth are large-spaced arranged and gradually becoming larger centrad ( Fig. 3 A). Mirror on right tegmen large, much longer than wide; secondary mirror developed (Fig. 4A). Tenth abdominal tergum deeply divided into two lobes, with slightly pronounced apex, triangular apex of which overlapping (Fig. 5A). Cerci moderately long, robust, heavy of equal width to a robust internal tooth in middle, with slightly constricted and approximately wide apical half; apical tooth small, pointed, and apical margin inclined upwards (Fig. 5E). Subgenital plate possessing a distinct midline and lateral carinae; triangular notch shorter than styli (Fig. 5K). Titillator with one pair of arms (Fig. 5I ). Coloration ( Fig. 1 ). Generally green when alive. Compound eyes and maxillas yellow. Basal three segments of antennae blackish brown, and flagella reddish brown. Shoulder of lateral lobe of pronotum, and base of male tegmen brown. Dorsal plane of male tegmen with irregular brown cells and spots. Dorsal part of female tegmen dark brown with green veinlets. Tarsi whitish brown. Lateral margin of abdomen white with brown sparse spots. Female ovipositor brown.
