Type material examined. Holotype Formosatettix longwangshanensis , ♁, China: Zhejiang prov., Anji County, Longwangshan , 20 July 1995, in IZSNU . Other material examined. topotypes Formosatettix longwangshanensis : 10♁ 8♀, China: Zhejiang prov., Anji County, Longwangshan , 30 July 2019, EMHU ; Topotypes Formosatettix tianmushanensis : 7♁ 15♀, China: Zhejiang prov., Linan County, Tianmushan , 22 July 2019, EMHU .

Notes. 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.

Distribution. China ( Zhejiang).
