人们花了相当大的努力来阐明四个科的系统发育关系。然而，目前还没有普遍接受的系统发育假说。因此，一些亚科之间的系统发育关系仍然不清楚；例如，枝叶亚科是一个有争议的类群，其中属之间的系统发育关系和所包括的一些属的边界不清楚，导致一些分类群难以识别。因此，迫切需要对叶甲亚科进行深入的系统发育分析。本研究根据中国蚱总科16属25种的线粒体细胞色素氧化酶亚基I(COI)、16S核糖体RNA(16S RRNA)和核18S核糖体RNA(18S RRNA)基因序列，构建了一个完整的系统发育框架，其中包括叶蝉亚科8属13种。利用数据集与贝叶斯推理(BI)和最大简约度(MP)相结合的方法进行系统发育推断，并重建了叶甲亚科的系统发育树。所有基于本研究结果的推论都支持叶蝉亚科是一个多系类群，在叶甲亚科中，四足类和结节类与叶蝉亚科有较近的亲缘关系，而Astrohanockia和Gibbotettix与叶蝉亚科的亲缘关系较近。此外，还描述和图示了枝叶亚科的一新属和新种：Hainantettix den，gen.11月和狭顶海鞘Hainantettix Structivertex Den，sp.11月
Considerable effort has been devoted to elucidating the phylogenetic relationships of tetrigides. However, there is still no commonly accepted phylogenetic hypothesis. Therefore, the phylogenetic relationships among some subfamilies remain unclear; e.g., Cladonotinae is a controversial group, in which the phylogenetic relationships between genera and the boundaries of some of the included genera are unclear, causing some of the taxa to be difficult to identify. Therefore, an in-depth phylogenetic analysis of Cladonotinae is urgently needed. In this study, a robust phylogenetic framework for the tetrigides was reconstructed based on the combined mitochondrial cytochrome oxidase subunit I (COI), 16S ribosomal RNA (16S rRNA), and nuclear 18S ribosomal RNA (18S rRNA) gene sequences of 25 species belonging to 16 genera of Tetrigoidea from China, which included 13 species from 8 genera of Cladonotinae. Phylogenetic inferences were performed using the combined dataset and Bayesian inference (BI) and Maximum Parsimony (MP) methods, and the phylogenetic tree of Cladonotinae was reconstructed. All inferences based on the results of the present study supported the Cladonotinae subfamily as a polyphyletic group; within the Cladonotinae subfamily, Tetradinodula , and Tuberfemurus were closely related to Tetriginae, while Austrohancockia and Gibbotettix showed a close relationship to the Scelimenidae subfamily. Additionally, a new genus and new species of the Cladonotinae subfamily are described and illustrated: Hainantettix Deng, gen. nov. and Hainantettix strictivertex Deng, sp. nov.
