Material examined. Holotype: ♂, Inside crevices on rock cliff of Baishi Mountain, Baishishan town, Laiyuan country, Baoding city, Hebei Province, China (114°41’41.56”E, 39°12‘16.94”N, alt. 1600m), 11-viii-2019, leg. Michael Lee. Paratype: 1♀, same data as in holotype. Remarks. The new species differ from Ptosoproctus lanzhouensis sp. nov. by: stridulatory file on male tegmina with less teeth; male 10th abdominal tergite posterior membranous projection strongly down-folded, with a gourdshaped median longitudinal furrow; male cercus inner tooth recurved and slightly incurve, apical part suddenly narrowly; male subgenital plate with a deeper triangular excision; titillators with longer apical arms, basal arms nearly right-angle curve; female ovipositor short and slightly curved, upper edge of apical part without wrinkles. Songs. The adults make calling songs at night. The song consists of echemes with syllables. Each echeme consist three syllables, echeme duration for 110–190 ms, echeme interval for 420–470 ms. Each syllable duration for 10–20 ms. Short syllables interval last for 10–15 ms. Etymology. The specific epithet is named after Baishi Mountain, the type locality. Distribution. China (Hebei). Known only from the type locality. Biology. This species inhabits Mt. Baishi’s steep marble cliff-face at around 1600m altitude. Type materials are collected from crevices on the cliff face, of which their body color well camouflaged against. A final-instar female nymph was also found (Fig. 9F). The collector returned to Mt. Baishi in mid-September 2021 to collect more material but returned in no avail, suggesting adult of the species may be short-lived due to Mt. Baishi’s low temperature., Published as part of Shen, Zi-Hao, Yin, Zi-Xu, Lee, Michael, Liu, Yi-Jiao, He, Zhu-Qing, Wang, Zi-Fan & Wang, Tong-Xin, 2021, Ptosoproctus gen. nov., a new genus with two new species of Shield-back Katydid with the first record of genus Eulithoxenus Bey-Bienko, 1951 from China (Orthoptera: Tettigoniidae: Tettigoniinae: Drymadusini), pp. 548-568 in Zootaxa 5067 (4) on pages 555-559, DOI: 10.11646/zootaxa.5067.4.4, http://zenodo.org/record/5683472

Remarks. Eulithoxenus emeljanovi differs from Eulithoxenus mongolica (Uvarov, 1928) by: posterior margin of male 10 th abdominal tergite with a pair of obtuse lobes, which have an extremely narrow furrow; male cercus broad and flat, apex short and obtuse, inner margin most part with a broad inner tooth; posterior margin of female 7 th abdominal sternite without notch. Based on the photos of type specimen in OSF and description of E. mongolica (Cigliano et al. 2021; Storozhenko 2004; Uvarov 1928), male 10 th abdominal tergite concave widely and without lobes; male cercus slightly incurved, inner tooth near the apex, short and acute, directed obliquely towards the base; posterior margin of female 7 th abdominal sternite with a notch. We concluded that the two species may not belong to the same genus, and furthermore specimens need to be checked to find out their relationships. Songs. The adults make calling songs at night. The song consists of echemes with syllables. Each echeme consist two syllables, echeme duration for 80–100 ms, echeme interval for 240–300 ms. Each syllable duration for 30–50 ms, syllables interval for 10–20 ms. Distribution.

MA veins curved upward, with 7 branches. Rs veins arised from 2/3 part of R vein. Hind wing shorter than tegmen. Stridulatory vein short, curved at the left side end, with about 30 teeth, two distinctly enlarged in the middle. Teeth distance subequal except for the two enlarged in the middle (Fig. 2D). Cu2 vein of left tegmen curved and slender, spectrum slender and rectangular (Fig. 2C). Ninth abdominal tergite with notch V-shaped; 10 th abdominal tergite with a shallow notch. Supra-anal plate triangular with medium groove at base. Cercus robust at base, inner middle with a slight projection; apical third finger-shaped and curved inwards; apex acute, slightly curved downward (Fig. 2E). Subgenital plate long with a medium longitudinal groove, lateral ridge well developed, posterior margin with a rounded excision; styli long and slender, almost as long as subgenital plate (Fig. 2F). Female: Pronotum dorsally flat; tegmina reaching tip of meta femora, slightly suppassing or not reaching tip of ovipositor. Cerci conical, apex acute, slightly curved inward (Fig. 2G).

It contains 1.635± 0.343s duration with first half loud and 3.158± 0.358s interval, but duration gradually decreased in the whole song. Comparison: This species is similar to H. expansus Wang & Shi, 2005 and H. inflatissimus Gorochov & Warchalowska-Sliwa, 1999, but differs from the former species by 1) male file of left tegmina shorter; 2) spectrum of male left tegmina slender and rectangular; 3) male Cu2 vein of left tegmina curved and slender; and differs from the latter species by 1) body smaller; 2) female tegmina narrow and shorter. Measurements (in mm): Male: SZ 37.17–39.10, PR 8.50–9.29, FW 29.60–31.69, HF 19.96–20.80; Female: SZ 34.02–37.69, PR 6.50–6.55, FW 26.89–29.91, HF 22.47–22.58, OV 15.34–15.75. Habitat: This species can be found in mountains areas under around 1000m above sea level in the west part of Taiwan, males can be heard stridulating in dense vegetations by the edge of laurel forest (Fig. 6). Etymology: The name formosanus refers to the island of Formosa, a former name of Taiwan. Note: This species was included in Matsumura (1931) and Kato (1932) but was misidentified as Hexacentrus munda Walker in both papers. In our field observations, calling males are usually ~10 meters away from each other, but additional males can sometimes be found near a calling male (Po-Wei Chen, personal experience). In an incident, a male with left front and middle legs missing were found within 30cm from a calling male. The remaining left front and middle coxae were darkened, indicating that the loss of limbs occurred some time previously. This male was possibly applying satellite behavior in attempt to intercept approaching females, as his fitness was obviously affected by the loss of limbs., Published as part of Chen, Po-Wei, Xie, Hui-Cong, Wu, Xue, Shen, Chu-Ze & He, Zhu-Qing, 2021, A new species of genus Hexacentrus Serville, 1831 from Taiwan (Orthoptera Tettigoniidae: Hexacentrinae), pp. 543-556 in Zootaxa 4933 (4) on pages 549-553, DOI: 10.11646/zootaxa.4933.4.5, http://zenodo.org/record/4556696, {"references":["Wang, J. - F., Shi, F. - M.

No morphological differences between Chinese and Vietnamese individuals including male cercus, tympana and other features (Fig. 4D ~F) have been observed. Apex of fastigium verticis gently bending to the left (Fig. 4B, D). Considering this individual was fed since nymph stage, no molt problem or injured made this malformation. Figures of holotype and paratype photographed by Ingrisch (OSF) also show same tendency of left bending. Thus, we believed this feature is spontaneous. Coloration. Overall colour yellow. Frons brown, mandibles black, pronotal disc with two lateral dark brown bands, variable in extension, in anterior area of disc subfused to a single band, which is split by a light line at base and interrupted by two light spots.

The song is distinct from other species with 5.98�� 0.17s duration and 12.59�� 0.50s interval (Fig. 5A). Note. The type species is from India. Without DNA data or songs data, it is difficult to confirm the state of this species. Judging by the COI genes data, the species from southern China, Malaysia and Indonesia are same (Fig. 6). Thus we identified this wide distributed species as M. elongata elongata provisional. This species has narrower wing from lateral view, compared with M. niponensis (Fig. 2 A���C)., Published as part of Liu, Yun-Fei, Shen, Chu-Ze, Gong, Pu, Zhang, Ling & He, Zhu-Qing, 2019, Three new species of genus Mecopoda Serville, 1831 from China (Orthoptera: Tettigoniidae: Mecopodinae), pp. 561-572 in Zootaxa 4585 (3) on page 566, DOI: 10.11646/zootaxa.4585.3.10, http://zenodo.org/record/2640098

This species is very similar to M. hainanensis (Fig. 2D), but the forewing is parallel in lateral view (the forewing of M. hainanensis is narrow in basal half and wide in apical half in lateral view). Female. Similar to male. Ovipositor straight (Fig. 2E). Coloration. Nearly brown. 0-2 black spots on the base of forewing. In same individual, the number of the black spots on left and right wing may be different. Etymology. The name fallax is used to emphasize its similarity to M. hainanensis. Measurements (in mm). Male: SZ 59.38-74.41, PR 7.47-9.53, FW 51.60-63.30, HW 54.21-66.23, HF 38.10- 48.26; Female: SZ 67.47, PR 7.8, FW 57.3, HW 60.61, HF 48.18, OV 26.64. Distribution. China (Yunnan). Song. The song is continuous with 0.572± 0.004s cycle repeatedly (Fig. 5C). Note. This species is only found from Yunnan, China. In Mangshi (Dehong, Yunnan, China), we found this species was sympatric and synchronous with M. elongata elongata.

Male: SZ 56.09-60.46, PR 7.92-10.62, FW 47.54-50.76, HW 49.16-52.95, HF 38.42- 40.14; Female: SZ 61.29-63.40, PR 8.32-8.74, FW 51.76-55.95, HW 55.04-57.02, HF 45.50-48.80, OV 30.11- 33.09. Distribution. China (Hainan). Song. The first part of this species is very long, sometimes it lasts one hour in wild. The first part contains 0.66± 0.03s duration and 0.88± 0.08s interval. The second part is continuous with 0.136± 0.001s cycle repeatedly (Fig. 5D). Note. It is an endemic species in Hainan Island (Fig. 6). However, M. elongata elongata and M. niponensis are also distributed in Hainan. We suspect that these two species are spread by human activity, because we only collected them near farm, but never in natural reserve.

He Zhu-Qing; 1 male, CHINA, Zhejiang Prov., Ningbo, Tiantongshan, 30-v-2015, coll. He Zhu-Qing. Description. Pronotum saddle-shaped, disc narrower from anterior margin in 1/5, and widened gradually with the posterior margin arc, lateral lobes of pronotum deepest in middle, posterior margin oblique with central concavity, tegmen slightly shorter than length of pronotum and extending to the 5th or 6th abdominal tergum. Leg spination, fore femora with 3 interior ventral spines, middle femur with 3 external ventral spines on left and 2 on right, hind femur with 6 interior spines on outer ventral margin, fore tibiae with 4 dorsal spines on exterior margin, 6 spines on both ventral margins, middle tibiae with 6 interior spines on both margins, 2 exterior and 5 interior spines on dorsal margins, hind tibiae with 24 exterior and 21 interior spines on dorsal margins, 9 and 13 spines on ventral margins. Tenth abdominal tergite with a flat U shaped notch in median portion, cerci curved with a small apical tooth (Fig. 3E). Female similar to male, tegmina covered by pronotum, but visible from lateral, ovipositor nearly straight with dorsal margin curved in basal 1/2, and ventral margin curved in basal 1/3. Coloration. Brown, upper side of lateral lobes of pronotum black with middle brown, Sc. vein white, left tegmen with a white spot on right (Fig. 2E), ovipositor yellow. Variation. External ventral spines on middle femur ranging from 0���4, interior spines on outer ventral margin of hind femur ranging from 2���3, interior spines on dorsal margins of middle tibiae ranging from 4���5. Etymology. The new species name interval refers to the pause in the male calling song.

Distribution. China (Zhejiang) Song. The trill is about 17.58s with 25.36s interval. In every trill, there are about 30 chirps. Every chirp is about 0.67s with 6 pulses (individual from Baimashan). The song of individual from Shaoxing is quit different in most parameter, but there is also a long interval between two trills as the feature of this species. Note. The new species is similar to A. (S.) fengyangensis Liu, 2013 in the shape of the cerci, but the tegmen is short. A white spot on the right of tegmen is another unique feature of this species. Song is very special with long interval, which makes it very difficult to catch., Published as part of Liu, Xiao-Tong, Chen, Guang-Yu, Sun, Bi-Xuan, Qiu, Xiao-Feng & He, Zhu-Qing, 2018, A systematic study of the genus Atlanticus Scudder, 1894 from Zhejiang, China (Orthoptera: Tettigoniidae: Tettigoniinae), pp. 170-180 in Zootaxa 4399 (2) on pages 176-177, DOI: 10.11646/zootaxa.4399.2.2, http://zenodo.org/record/1206576, {"references":["Liu, C. - X.

He Zhu-Qing. Description. Pronotum saddle-shaped, disc rectangle in 1/3, and widened gradually with the posterior margin arc, lateral lobes of pronotum deepest in middle, posterior margin oblique with central concavity, tegmen as long as pronotum and extending to the 7th or 8th abdominal tergum. Leg spination, fore femora with 2 interior ventral spines on left and 1 on right, middle femur with 1 external ventral spines, hind femur with 3 interior spines on outer ventral margin and 4 on inner ventral margin, fore tibiae with 3 dorsal spines on outer exterior margin, and 1 spine on the inner exterior margin, 6 spines on both ventral margins, middle tibiae with 3 dorsal spines on outer exterior margin, and 2 spine on the inner exterior margin, 6 ventral spines on both margins, hind tibiae with 21 exterior and 17 interior spines on dorsal margins, 7 and 9 spines on ventral margins. Tenth abdominal tergum with a small U shape notch on central, cerci curved with a small tooth in the middle (Fig. 3D). Female Nymph, similar to male, no tegmen, ovipositor nearly straight. Coloration. Brown, upper side of lateral lobes of pronotum black, head and hind femur yellow. Variation. Neither two nymphs has spine on the inner exterior margin on fore tibiae. It is unclear whether it will appear as it matures. Etymology. The name fallax is used to emphasize its similarity to A. (S.) fengyangensis Liu, 2013. Measurements (in mm) male: body length 31.2, pronotum length 11.9, tegmen length 13.6, hind femur length 32.9; female (nymph): body length 23.3, pronotum length 10.5, hind femur length 29.8, ovipositor length 22.5. Distribution. China (Zhejiang) Song. The song of this species is similar to that of A. (S.) magnificus with 0.25s chirp cycle duration. But in every chirp, 6 or 8 pulses are clearly present. Note. This new species is very similar to A. (S.) fengyangensis Liu, 2013 (Fig. 2 CD), but the new species has one more row of spines on the fore tibia. There are also differences in song and the shape of the cerci (Table 2, Fig. 3CD). The ventral surface of the abdomen is red when alive, while that of fengyangensisi is yellow or lime. This species is distributed in the southernmost part of Zhejiang, and there seems to be geographic isolation on two species (Fig. 4)., Published as part of Liu, Xiao-Tong, Chen, Guang-Yu, Sun, Bi-Xuan, Qiu, Xiao-Feng & He, Zhu-Qing, 2018, A systematic study of the genus Atlanticus Scudder, 1894 from Zhejiang, China (Orthoptera: Tettigoniidae: Tettigoniinae), pp. 170-180 in Zootaxa 4399 (2) on pages 175-176, DOI: 10.11646/zootaxa.4399.2.2, http://zenodo.org/record/1206576, {"references":["Liu, C. - X.
