Holotype: male, CHINA, Yunnan Prov., Yingjiang, Nabang, E 97.57, N 24.75, 23-viii-2019, coll. He Zhu-Qing. (depository: East China Normal University , China) GoogleMaps

Paratype: 2 males, same data as holotype GoogleMaps .

Male: Body large for this genus ( Fig 3E View FIGURE 3 ). Head: head little wider than anterior margin of pronotum ( Fig. 1C View FIGURE 1 , 3E View FIGURE 3 , 4B View FIGURE 4 ), vertex not flattened, frontal rostrum as wide as 1st antennal joint ( Fig. 4A View FIGURE 4 ), 3rd–4th segments of maxillary palpi elongated, 5th segment triangular. Pronotum: pronotum pubescent and posteriorly widened ( Fig. 4B View FIGURE 4 ), no lateral carina, anterior and posterior margin straight, fore tibia with oval tympanum on outer side ( Fig. 4C View FIGURE 4 ), but a slit on inner side ( Fig. 4D View FIGURE 4 ), hind tibia with three pairs of dorsal spurs and five apical spurs, tegmen long and narrow, almost extending to apex of abdomen, mirror large and oval. Genitalia: Epiphallic lateral lobe long with three minute teeth on the apex of each lateral lobe ( Fig. 4E&F View FIGURE 4 ).

Female: unknown.

Coloration: Overall color yellow. Frons reddish brown with two red longitudinal bands from head to posterior margin of pronotum; lateral lobes of pronotum red. Two black stripes on the outer pagina of hind femur, and one on the inner side, a black spot on the dorsal and lateral side near hind femur near apical portion, a small black spot on the opposite side of above spot, in the ventral side of hind femur near apical portion.

Comparison: This species can be easily distinguished from other species by the combination of red bands on pronotum and black stripes on the hind femur ( Fig. 1C View FIGURE 1 ).

Measurements (in mm): Male: SZ 7.6–7.7, PR 1.2–1.3, FW 5.5–5.6, HF 5.8–5.9.

Distribution: China (Yunnan).

Etymology: The specific epithet wuyong is for the Chinese phonetic alphabet. It means “improperly use”. Because this new species was misidentified as S. rufonotata for many years. See details in discussion.

Song: The song was stereotyped with 78 chirps /minute. Each chirp contained 16.4±0.55 pulses, and continued 0.439±0.015 s ( Fig. 6 View FIGURE 6 ).
