Tetrix gibberosa (Wang Zheng) is a high-backed pygmy grasshopper species from eastern PR China. Due to its reduced hind wings and pleomorphism (length changes of hind wings and the hind pronotal process, which is generally called macropterous and brachypterous morphs), the species have been described into different species which involve several taxonomically confused genera. This study clarifies its taxonomy and distribution and provides ecological information for the species. At the same time, we comment the relationships of related genera in the subfamily Tetriginae, including Tetrix Latreille, Exothotettix Zheng Jiang, Alulatettix Liang, Aalatettix Zheng Mao, Formosatettix Tinkham, and Formosatettixoides Zheng. Additionally, we report for the first time that nematodes can parasitize pygmy grasshoppers. New synonyms are proposed: Tetrix gibberosa (Wang Zheng, 1993) = Alulatettix bulbosus Zheng Zhong, 2001, syn. nov., = Exothotettix jiangxiensis Liang Jia, 2008, syn. nov., = Tetrix glochinota Zhao, Niu Zheng, 2010, syn. nov., = Alulatettix nigromarginalis Zhang, Deng Zha, 2014, syn. nov., = Alulatettix flavotibialis Zhang, Deng Zha, 2014, syn. nov..
中国东部的多刺矮蝗（Wang Zheng）是一种后背部高耸的小型蝗蝻物种。由于其缩小的后翅和多态性（后翅和后前胸过程的长度变化，通常称为长翅和短翅形态），该物种已被描述为不同的物种，涉及几个分类上混淆的属。本研究阐明了其分类和分布，并为该物种提供了生态信息。同时，我们还对 Tetriginae 亚科的相关属之间的关系进行了评论，包括 Tetrix Latreille、Exothotettix Zheng Jiang、Alulatettix Liang、Aalatettix Zheng Mao、Formosatettix Tinkham 和 Formosatettixoides Zheng。此外，我们首次报道线虫可以寄生小型蝗蝻。提出了新的同义词：Tetrix gibberosa（Wang Zheng，1993）=Alulatettix bulbosus Zheng Zhong，2001，syn. nov.，=Exothotettix jiangxiensis Liang Jia，2008，syn. nov.，=Tetrix glochinota Zhao，Niu Zheng，2010，syn. nov.，=Alulatettix nigromarginalis Zhang，Deng Zha，2014，syn. nov.，=Alulatettix flavotibialis Zhang，Deng Zha，2014，syn. nov.。
