Bioacoustics of Radigryllacris longiproceris

Figure 1 Description. Female. Body large. Face ovoid; fastigium verticis about 2 times as wide as scape; fastigium frontis separated from fastigium verticis by a very fine suture ( Fig. 1A ). Ocelli distinct, median ocellus slightly larger than lateral ocelli ( Fig. 1A ). Anterior margin of pronotum projecting in middle, posterior margin nearly straight ( Fig. 1C ); lateral lobes longer than deep, anterior angle widely rounded, posterior angle rounded angular, humeral sinus shallow ( Fig. 1B ). Fore coxae with 1 small spine; fore and middle femora unarmed, tibiae ventrally with 4 pairs of spurs and 1 pair of apical spurs; dorsal surface of middle tibiae with 1 internal spine. Hind femora with 4 internal and 5 – 6 external spines on ventral surface; dorsal surface of tibiae with 6 pairs of spines and 1 pair of apical spurs, ventral surface with 1 pair of subapical spurs and 2 pairs of apical spurs. Second and third abdominal tergites with few, very minute stridulatory pegs ( Fig. 1D ). Seventh abdominal sternite wider than long, ventral surface of basal area with 1 process reaching the middle area of subgenital plate, basal half of the process triangular in ventral view, apical half long and slender, the lateral margin faintly narrowing; posterior margin with small notch ( Fig. 1G ). Subgenital plate transverse; the lateral margins with basal area convex, middle area constricted, apical half faintly narrowing; posterior margin triangular concave with the lateral lobes triangular ( Fig. 1G ). Ovipositor with basal half straight, apical half faintly curved dorsad; hardly longer than hind femur; dorsal margin of apices slightly expanded ( Fig. 1H ). Male. Unknown. Coloration. Body green. Eyes brown. Ocelli pale yellow. Ovipositor brown. Measurements (mm). Female: BL 31.13–32.0, PL 8.81–9.12, HFL 18.84–19.51, TL 31.52–32.6, OvL32.10–33.4.
