3922878EB769795FFF7DF119FCDBD465.taxon	description	Description and differential diagnosis. This genus is characterized by follow combination of features: head not exserted above upper level of pronotum; fastigium of vertex in dorsal view surpassing the anterior margin of eyes, generally much wider than width of one compound eye from above; anterior margin of fastigium arched or straight; pronotum compressed, dorsum tectiform, usually without humeral angle; in dorsal view, anterior margin of pronotum arcuate protruding, truncate or angular projecting; the apex of pronotum rounded or bilobate; in profile, median carina of pronotum high, arch-like or straight; posterior angles of lateral lobes turned downwards, apex of posterior angles obtuse rounded; posterior margins of lateral lobes of pronotum only with ventral sinus, the tegminal (upper) sinus absent; tegmina and hind wings invisible (generally vestigial hidden under pronotum or apterous); fore and middle femora elongated, with straight or undulated ventral margins. Formosatettix is most similar to Alulatettix Liang, 1993. The difference between the two genera occurs in the posterior margins of lateral lobes of pronotum and the flying organs. In Formosatettix, the posterior margins of lateral lobes of pronotum only with ventral sinus and tegminal (upper) sinus is absent; tegmina and hind wings are generally invisible (generally strongly reduced to minute scales completely hidden under pronotum or apterous). In Alulatettix, the posterior margins of lateral lobes of pronotum with ventral sinus and tegminal (upper) sinus; tegmina visible; and hind wings abbreviated but visible (not uncovering the pronotum). Formosatettix is also similar to Aalatettix Zheng & Mao, 2002. The difference between the two genera is in tegminal sinus of the posterior margins of lateral lobes of pronotum. In Formosatettix, tegminal (upper) sinus is absent; in Aalatettix, tegminal (upper) sinus is present but inconspicuous. Therefore, Aalatettix may be considered a synonym of Formosatettix, but more studies are required to confirm this inference. Composition and distribution: Altogether, 67 species are now assigned to the genus Formosatettix and found in China, Russia, Korea, Japan, Pakistan and Nepal (Fig. 1).	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

3922878EB76E795AFF7DF549FC87D6A1.taxon	materials_examined	Type material examined. Holotype Formosatettix torulosinota, ♀, larva, China: Yunnan prov., Weishan County, 13. June 1996, in IZSNU. Notes. We examined the type specimen of Formosatettix torulosinota and found that it has hind wings. Therefore, it belongs to a winged pygmy grasshopper species other than Formosatettix. However, its hind wings have only radial venation, without cross-veins (Fig. 2 C), indicating that it is a nymph. The type specimen of F. torulosinota is in poor condition with the abdomen and hind legs missing, but there is evidence indicating that it is a nymph. In the original description of Formosatettix torulosinota, Zheng & Mao (2002) provided a drawing showing that the antegenicular teeth of the dorsal margin before the knee of the hind femora were absent (Fig. 2 E). Formosatettix torulosinota (Zheng & Mao, 2002) syn. n. represents a nymph of Bolivaritettix circocephalus. It has slightly truncate posterior angles in the pronotal lateral lobes, dense protuberances on the pronotal surface, obtuse humeral angle, interhumeral carina, and a narrow vertex.	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

We examined the type specimen of Formosatettix hainanensis and found that it has hind wings. Therefore, it does not belong to Formosatettix. The hind wings of the type specimen have only radial venation, without crossveins (Fig. 3 B), indicating that it is a nymph. Unfortunately, the hind legs of the type specimen are missing. In the original description of Formosatettix hainanensis, Zheng (2012) provided a drawing showing that the antegenicular teeth of the dorsal margin before the knee of the hind femora were absent (Fig. 3 D), indicating that the specimen is a nymph. Formosatettix hainanensis (Zheng, 2012) syn. n. represents a nymph of Criotettix bispinosus, which has a widened vertex, elongated lateral carinae of prozona, and a slightly elevated median carina of the pronotum before shoulders.	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

We examined the type specimens of Pseudepitettix guangxiensis and Formosatettix guangxiensis, and found that the structures, type locality and coloration of the body are the same in both taxa. Therefore, a new synomimy is here established. The comparison of the holotype of Pseudepitettix guangxiensis and Formosatettix guangxiensis and their additional specimens show that these taxa are conspecific and characterized by the vertex is distinctly surpassing anterior margin of eyes as an evenly broad, rounded process; the vertex is much wider than one of the eyes; the apex of the hind pronotal process is concave.	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

We examined the type specimens of Formosatettix huapingensis, F. nanlingensis, and F. guposhanensis and found that the structures and coloration of the body are the same in these three taxa. Therefore, we consider F. nanlingensis and F. guposhanensis as synonyms of F. huapingensis. We also examined the type specimens of F. nanlingensis and F. undulatifemura and found that body structures, type locality (Nanling National Forest Park), and body coloration were the same in both taxa. The type specimen of F. undulatifemura was determined to be a nymph (antegenicular teeth of the dorsal margin before the knee of the hind femora were absent (Fig. 9 A )). Thus, F. undulatifemura is considered to be a synonym of F. huapingensis. These taxa are conspecific and characterized by the width of the vertex between the eyes being 2.2 – 2.5 times the width of the compound eye; the anterior margin of pronotum is truncate or slightly arcuate protruding; the lower margin of the hind process is straight and the lateral carinae of metazoan is also slightly straight; the lower carinae of fore and mid femora is straight or slightly sinuate.	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

Formosatettixoides yunnanensis has a posterior margin of the lateral lobe of pronotum only with ventral sinus and tegminal (upper) sinus absent; tegmina and hind wings reduced to minute scales completely hidden under pronotum, and it belongs to the genus Formosatettix. This species can be identified by the smooth body; the vertex is much wider than one of the eyes; the pronotum is strongly elevated and arch-like; the anterior margin of the pronotum is obtuse and protruding; the apex of the hind pronotal process is concave; the middle femur is much wider than the fore femur. Zheng (1992) described Formosatettix yunnanensis Zheng, 1992 from Yunnan (Pingbian). Here, Formosatettixoides yunnanensis Zheng & Mao, 1997 is moved to the genus Formosatettix. Formosatettix yunnanensis Zheng & Mao, 1997 must therefore be renamed as a secondary homonym based on the rule of Article 57.3 of the International Code of Zoological Nomenclature (ICZN 1999).	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.

Not only did we examine the holotype of Formosatettix longwangshanensis and compared with type specimen pictures and the description of Formosatettix tianmushanensis (Zheng & Li, 2001), but also we compared the topotypes of these two species and found that morphology and distribution are completely identical in both taxa. Thus, we synonymise F. tianmushanensis with F. longwangshanensis. The two taxa are conspecific and characterized by the width of the vertex between the eyes 2.0 – 2.2 times the width of a compound eye; anterior margin of pronotum obtuse protruding; median carina of pronotum arch-like; lower margin of hind process distinctly curved; lower carinae of fore and mid femora straight or slightly sinuate.	en	Deng, Wei-An, Luo, Jie-Ling, Huang, Chao-Mei, Lin, Li-Liang (2023): Review of the genus Formosatettix Tinkham (Orthoptera: Tetrigidae) with description of new taxa, new synonymy and an updated key to species.
