It is morphologically similar to S. rufonotata but differs in having dark-brown setae on the 5th segment of maxillary palp (Fig. 4A-F), an ectoparamere with rounded corner (Fig. 5A-C), and a smaller inner tympanum (Fig. 5D-G).</p><p>Materials examined.</p><p>Holotype: China • ♂; Xizang, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=97.02033&amp;materialsCitation.latitude=28.47" title="Search Plazi for locations around (long 97.02033/lat 28.47)">Zayu</a>; 28°28.20'N, 97°01.22'E; 1565 m); 9 July 2023; He Zhu-Qing leg.; ECNU 4969 . Paratypes: 2♂, ECNU 4961, ECNU 4970 &amp; 2♀, ECNU 4967, ECNU 4968; same data as for holotype .</p><p>Description.</p><p>Male. Body size small. Head slightly wider than anterior margin of pronotum, occiput slightly convex (Figs 1A, 2A); frontal rostrum about as wide as first antennal segment, with two rows of setae extending to vertex (Fig. 2C); vertex not dorsally flattened; antennae long and pubescent; compound eyes slightly protruding forwards; 5th segment of maxillary palpi triangular and swollen (Fig. 2D). Pronotum with setae, posterior margin widened; fore tibiae armed with two oval tympanums, with outer one bigger than inner one (Fig. 3A, B); hind tibiae bearing three pairs of dorsal spurs (Fig. 3C) and five apical spurs (two internal ones distinctly longer and three external ones shorter); tegmina barely reaching apex of abdomen. Cercus with long, thin hair.</p><p>Genitalia. Pseudepiphallus separated into two lateral parts joined by a straight sclerotized bridge. Pseudepiphallic lophi curved inwards with 3 or 4 forks apically. Posterior marginal area of endoparameron with minute teeth and short setae (Fig. 3E, F).</p><p>Female. Similar to male (Fig. 1B). Tegmina slightly convex and not extending to abdominal apex (Fig. 2B). Ovipositor long and curved upwards, finely denticulate on dorsal and ventral sides (Fig. 2E).</p><p>Coloration. Body brown; legs yellowish brown. Head orange and marked with five vertical red stripes extending to pronotum in dorsal view. Setae on the 5th segment of maxillary palpi dark brown (Fig. 4D, E). Abdomen with 1 lateral red spot on both sides of each abdominal segment in female. Each hind femur with a dark-brown stripe near knees when alive (Fig. 1A, B) but disappearing after drying (Fig. 3D). Ovipositor dark brown; apical half darker than basal part.</p><p>Variation. A paratype (ECNU 4961) has seven dorsal spurs on the hind tibiae (four internal ones and three external ones), while all the other examined specimens bear six dorsal spurs on the hind tibiae.</p><p>Measurements.</p><p>Holotype: ♂ BL 5.63, PL 1.09, FWL 4.08, HFL 4.35; Paratypes: ♂ BL 5.86-6.16, PL 1.05-1.18, FWL 4.09-4.14, HFL 4.07-4.30; ♀ BL 5.55-5.63, PL 1.19-1.27, FWL 3.36-3.41, HFL 4.19-4.30, OL 2.05-2.07.</p><p>Distribution.</p><p>China (Xizang).</p><p>Etymology.</p><p>The specific epithet yayun is for the Chinese phonetic alphabet, 雅韵, which means "beautiful music".</p><p>Molecular study</p><p>In total, 39 COI sequences including our newly described S. yayun He, sp. nov., as well as the COI sequence of Amusurgus genji as the outgroup, were obtained. The results of the two molecular methods identified 11 putative species, which largely conform to the distance tree inferred from the NJ topology and are all consistent with separating S. yayun He, sp. nov. as a species (Fig. 6).</p><p>Song analysis</p><p>The calling song of Svistella yayun sp. nov. is stereotyped with 37.11 ± 5.00 [30-42] echemes/minute. Each echeme continues 0.966 ± 0.049 [0.901-1.094] second and consists of 19.77 ± 1.060 [18-24] syllables (Fig. 7). The peak frequency is 5332.420-5594.540 Hz (Fig. 7). Although S. rufonotata and S. yayun are similar morphologically, they can be distinguished by their songs. The characteristics of the songs of all included species in PCA are shown in Table 1. The species S. fallax was not included in PCA, because the audio file was lost, and the peak frequency for this species was unavailable.</p><p>PCA results are shown in Fig. 8. The extracted components PC1 eigenvectors accounted for 57.90% of the variance, PC2 for 24.04%, PC3 for 15.05%, PC4 for 2.02%, and PC5 for 0.99%. Except for S. wuyong and S. malu, the remaining species can be clearly identified via the analysis of their calling songs.</p><p>Other materials examined</p><p>Svistella rufonotata: China • ♂; bought from Flowers-birds Market; September 2016; He Zhu-Qing; ECNU 266 • ♂; Yunnan, Mengla, Wangtianshu (望天树景区); 21°37.04'N, 101°33.56'E; 26 April 2017; He Zhu-Qing leg.; ECNU 494 • ♂; Hainan, Baisha, Nankai; 19°04.78'N, 109°22.57'E; 18 March 2019; He Zhu-Qing leg.; ECNU 1634 • ♂; Fujian, Wuyishan; 27°41.28'N, 117°44.38'E; 22 September 2018; He Zhu-Qing leg.; ECNU 1756.</p></div>	https://treatment.plazi.org/id/4F6B19D82A7A5BC0B11B401A00099841	Public Domain	No known copyright restrictions apply.
